Example 1

(6) The Body 23 of the Gas Powered Gun that is Powered by Compressed Gas, with No Loss-Making Expansion Space, where the Body 23 is Positioned in a Movable Bolt Cylinder 2

(7) The duralumin cylinder 2 is equipped with pressure chamber 3 and the striker space. The pressure chamber 3 is directly, through the seat 10 of the valve 9 connected to the projectile opening 29 of the barrel 8, where the connection of the barrel 8—pressure chamber 3 is lockable by the valve 9 fitting closely to the centre of the seat 10 of the valve 9. The valve 9 is connected to the tie rod 11 of the valve 9, which is mounted in one axis with the barrel 8 and passes through the pressure chamber 3. In addition, the tie rod 11 passes through the special section wall 30 separating the pressure chamber 3 from the striker space 4, the striker space 4 and along with the spring 12 of the tie rod 11 it is seated in the lock 17 of the bolt cylinder 2, which closes both the striker space 4 and the entire bolt cylinder 2. In the striker space 4, after passing through the pressure chamber 3 and the special section wall 30, the tie rod 11 of the valve 9 is fitted with the spring 15 of the striker 14, the striker 14 and the stop 13 of the striker 14.

(8) The pressure chamber 3 is manufactured from duralumin, it is turned, milled, or cast in the bolt cylinder 2 and has an irregular inner shape of the volume of 12.7 ml centred around the axis of the barrel 8. The pressure chamber 3 is fitted with the supply 6 of pressurized gas connected by a flexible hose 7 to the source of pressurized gas, meaning the pressurized gas canister. By the supply 6 of pressurized gas, pressurized gas is constantly supplied from the canister. to the pressure chamber 3. The pressure chamber 3 is on its connection to the barrel 8 fitted with a circular seat 10 of the valve 9 made of polished duralumin with a centrally positioned opening and with an inlet contour. The opening of the seat 10 of the valve 9 is closely fitted by the projectile opening 29 of the barrel 8, whereby the seat 10 of the valve 9 is fitted with a centralized section 31 allowing the barrel 8 to be inserted. The seat 10 of the valve 9 is connected with the socket 25 of the projectile 24, which is positioned in the loading space under the barrel 8 closely fitting to the section 31 allowing the barrel 8 to be inserted and has the shape of a half-round groove. When the gun is being loaded, where the valve 9—closed pressure chamber 3 is displaced from the projectile opening 29 of the barrel 8, the projectile 24 is inserted into the half-round groove of the socket 25 of the projectile 24. When the pressure chamber 3 approaches the barrel 8 subsequently, the projectile 24 is inserted from the socket 25 into the projectile opening 29 of the barrel 8 and the projectile opening 29 of the barrel 8 then closely fits to the section 31 for the insertion of the barrel 8 of the seat 10 of the valve 9. The tie rod 11 of the valve 9, which passes through the entire bolt cylinder 2 from the seat 10 of the valve 9 up to the lock 17 of the bolt cylinder 2, is manufactured from steel and has the shape of a rod, meaning a long cylinder with thread in the area where the tie rod 11 of the valve 9 is mounted. The end of the tie rod 11 positioned in the pressure chamber 3 is fitted with the plastic self-centring valve 9 having the shape of a cylinder with inlet contour. The inlet contour of the plastic valve 9 corresponds with the inlet contour of the duralumin seat 10 of the valve 9, thanks to which when the valve 9 fits closely to the seat 10 the opening in the seat 10 is reliably closed. The opening in the seat 10 of the valve 9 has a smaller diameter than that of the valve 9.

(9) Onto the tie rod 11 of the valve 9, after passing through the pressure chamber 3 and the special section wall 30, the spring 15 of the striker 14 is put on, the diameter of which is larger than that of the tie rod 11 of the valve 9. The spring 15 of the striker 14 is partly implanted in the special section wall 30. Then on the tie rod 11 of the valve 9a steel striker 14 of the shape of a special section annulus with the seat 19 of the spring 15 of the striker 14 is put, where the spring 15 of the striker 14 is partially implanted in the seat 19 of the spring 15. The inner diameter of the striker 14, or the opening 18 for the tie rod 11 of the valve 9 respectively, is larger than the diameter of the tie rod 11 of the valve 9 and smaller than the diameter of the spring 15 of the striker 14. The outer diameter of the striker 14 is greater than the diameter of the spring 15 of the striker 14. The striker 14 is on its outer case equipped with the annular section 20 for the catch 16 of the striker 14 and with the annular section 22 for the stop 21 of the bolt cylinder 2. The catch 16 of the striker 14 is made of stainless steel and is positioned in the wall of the bolt cylinder 2 at a distance from the special section wall 30 corresponding to the length of the assembly of the striker 14—compressed spring 15 of the striker 14. The catch 16 of the striker 14 is connected to the trigger mechanism 26. Onto the tie rod 11 of the valve 9 is then welded a stop 13 of the striker 14, in the form of two oppositely located steel projections on the tie rod 11 of the valve 9. The stop 13 of the striker 14 has a larger diameter than the inner diameter of the striker 14.

(10) All the disclosed components, with the exception of the barrel 8 are located in the bolt cylinder 2 and together form the bolt 1. After the bolt 1 is mounted in the gun powered by compressed gas, the bolt 1 remains movable in the axis of the barrel 8. The gun is fitted with a static stop 21 of the bolt cylinder 2 positioned at a distance from the special section wall 30 that is greater than the length of the assembly of the striker 14—released spring 15 of the striker 14 and at the same time smaller than the length of the striker space 4. The stop 21 of the bolt cylinder 2 is intended for stopping the moving striker 14 in the bolt cylinder and compressing the spring 15 of the striker 14.

(11) In Action:

(12) Before firing, it is necessary to displace the bolt 1 away from the barrel 8 to expose the loading space 28 and the socket 25 of the projectile 24. Along with the bolt cylinder 2, all components positioned therein move, until the section 22 for the stop 21 of the bolt cylinder 2 strike against the stop 21 of the bolt cylinder 2. At this moment the striker 14 is stopped in its movement, regardless of the fact that the bolt cylinder 2 continues moving away from the barrel 8. Thanks to this, the spring 15 of the striker 14, which is positioned between the striker 14 and the special section wall 30 that is moving along with the bolt cylinder 2, is compressed. When the spring 15 of the striker 14 is compressed and the section 20 for the catch 16 of the striker 14 positioned on the striker 14 and the catch 16 of the striker 14 positioned in the wall of the still moving bolt cylinder 2 approach one another, the catch 16 catches the section 20 and secures the striker 14 with the compressed spring 15 of the striker 14. For live firing, the projectile 24 is inserted into the socket 25 of the projectile 24. The entire bolt 1 with the secured striker 14 and the compressed spring 15 of the striker 14 returns along its axis, or the axis of the barrel 8 respectively, to the projectile opening 29 of the barrel 8, to which it is connected again. If the projectile 24 is inserted into the socket 25 of the projectile 24, then when the bolt 1 approaches the projectile opening 29 of the barrel 8, the projectile 24 is inserted into the projectile opening 29 of the barrel 8.

(13) For firing, it is necessary to release the striker 14, or the striker spring 15. This is attained by releasing the catch 16 of the striker 14 connected to the trigger mechanism 26, by which also the spring 15 of the striker 14 is released and throws the striker 14 towards the stop 13 of the striker 14 in the opposite direction of firing. The striker 14 strikes the stop 13 of the striker 14 and thanks to the kinetic energy transferred to the striker 14 by the spring 15 of the striker 14 the tie rod 11 of the valve 9 is carried along with the striker 14 stricken by the stop 13 of the striker 14 in the direction opposite to that of firing. The moving tie rod 11 of the valve 9 pulls away the valve 9 closely fitting to the seat 10 of the valve 9, thus opening the mutually connected pressure chamber 3 and the barrel 8. Pressurized air from the pressure chamber 3 flows around the valve 9 and the seat 10 of the valve 9 into the barrel 8, by which firing is implemented. If in the projectile opening 29 of the barrel 8 projectile 24 is placed, the projectile 24 is fired from the barrel 8 with the full force of the pressurized air from the immediately adjacent pressure chamber 3.

(15) The duralumin cylinder 2 is equipped with pressure chamber 3 and the striker space. The pressure chamber 3 is directly, through the seat 10 of the valve 9 connected to the projectile opening 29 of the barrel 8, where the connection of the barrel 8—pressure chamber 3 is lockable by the valve 9 fitting closely to the centre of the seat 10 of the valve 9. The valve 9 is connected to the tie rod 11 of the valve 9, which is mounted in one axis with the barrel 8 and passes through the pressure chamber 3. In addition, the tie rod 11 passes through the special section wall 30 separating the pressure chamber 3 from the striker space 4, the striker space 4 and along with the spring 12 of the tie rod 11 it is seated in the lock 17 of the bolt cylinder 2, which closes both the striker space 4 and the entire bolt cylinder 2. In the striker space 4, after passing through the pressure chamber 3 and the special section wall 30, the tie rod 11 of the valve 9 is fitted with the spring 15 of the striker 14, the striker 14 and the stop 13 of the striker 14.

(16) The pressure chamber 3 is manufactured from duralumin. It is turned, milled, or cast in the bolt cylinder 2 and has an irregular inner shape of the volume of 2 ml centred around the axis of the barrel 8. The pressure chamber 3 is fitted with the supply 6 of pressurized gas connected by a flexible hose 7 to the source of pressurized gas, meaning the pressurized gas canister. By the supply 6 of pressurized gas, pressurized gas is constantly supplied from the canister to the pressure chamber 3 through the pressure controller. The pressure chamber 3 is on its connection to the barrel 8 fitted with a circular seat 10 of the valve 9 made of polished brass with a centrally positioned opening and with an inlet contour. The opening of the seat 10 of the valve 9 is closely fitted by the projectile opening 29 of the barrel 8, whereby the seat 10 of the valve 9 is fitted with a centralized section 31 allowing the barrel 8 to be inserted. The seat 10 of the valve 9 and the socket 25 of the projectile 24 form one component, where the socket 25 of the projectile 24 is positioned in the loading space under the barrel 8 closely fitting to the section 31 allowing the barrel 8 to be inserted and has the shape of a half-round groove. When the gun is being loaded, closed pressure chamber 3 is displaced from the projectile opening 29 of the barrel 8, the projectile 24 is inserted into the half-round groove of the socket 25 of the projectile 24. When the pressure chamber 3 approaches the barrel 8 subsequently, the projectile 24 is inserted from the socket 25 into the projectile opening 29 of the barrel 8 and the projectile opening 29 of the barrel 8 then closely fits to the section 31 for the insertion of the barrel 8 of the seat 10 of the valve 9.

(17) The tie rod 11 of the valve 9, which passes through the entire bolt cylinder 2 from the seat 10 of the valve 9 up to the lock 17 of the bolt cylinder 2, is manufactured from steel and has the shape of a screw, meaning a long threaded cylinder, and the tie rod is extended in the area of the stop 13 of the striker. This means that the stop 13 of the striker 14 and the tie rod 11 of the valve 9 are made of one piece. The end of the tie rod 11 positioned in the pressure chamber 3 is fitted with the brass self-centring valve 9 having the shape of a cylinder with inlet contour and with silicone seal, where the valve 9 is screwed onto the tie rod. The inlet contour of the brass valve 9 corresponds with the inlet contour of the brass seat 10 of the valve 9, thanks to which when the valve 9 fits closely to the seat 10 the opening in the seat 10 is reliably closed. The opening in the seat 10 of the valve 9 has a smaller diameter than that of the valve 9. Onto the tie rod 11 of the valve 9, after passing through the pressure chamber 3 and the special section wall 30, the spring 15 of the striker 14 is put on, the diameter of which is larger than that of the tie rod 11 of the valve 9. The spring 15 of the striker 14 is partly implanted in the special section wall 30. Then on the tie rod 11 of the valve 9a bronze striker 14 of the shape of a special section annulus with the seat 19 of the spring 15 of the striker 14 is put, where the spring 15 of the striker 14 is partially implanted in the seat 19 of the spring 15. The inner diameter of the striker 14, or the opening 18 for the tie rod 11 of the valve 9 respectively, is larger than the diameter of the tie rod 11 of the valve 9 and smaller than the diameter of the spring 15 of the striker 14. The outer diameter of the striker 14 is greater than the diameter of the spring 15 of the striker 14. The striker 14 is on its outer case equipped with the annular section 20 for the catch 16 of the striker 14 and with the annular section 22 for the stop 21 of the bolt cylinder 2. The catch 16 of the striker 14 is made of stainless steel and is positioned in the wall of the bolt cylinder 2 at a distance from the special section wall 30 corresponding to the length of the assembly of the striker 14—compressed spring 15 of the striker 14. The catch 16 of the striker 14 is connected to the trigger mechanism 26. The stop 13 of the striker 14 has a larger diameter than the inner diameter of the striker 14.

(18) All the disclosed components, with the exception of the barrel 8 are located in the bolt cylinder 2 and together form the bolt 1. After the bolt 1 is mounted in the gun powered by compressed gas, the bolt 1 remains movable in the axis of the barrel 8. The gun is fitted with a static stop 21 of the bolt cylinder 2 positioned at a distance from the special section wall 30 that is greater than the length of the assembly of the striker 14—released spring 15 of the striker 14 and at the same time smaller than the length of the striker space 4. The stop 21 of the bolt cylinder 2 is intended for stopping the moving striker 14 in the bolt cylinder and compressing the spring 15 of the striker 14.

Example 2

(19) The System of Direct Connection of the Pressure Chamber to the Barrel

(20) The projectile opening 29 of the barrel 8 opens directly to the pressure chamber 3, where the connection of the barrel 8—pressure chamber 3 is lockable by the valve 9 closely fitting to the centre of the circular seat 10 of the valve 9. The valve 9 is connected to the tie rod 11 of the valve 9, which is mounted in one axis with the barrel 8 and passes through the pressure chamber 3. After passing through the pressure chamber 3 the tie rod 11 of the valve 9 is fitted with the spring 15 of the striker 14, the striker 14 and the stop 13 of the striker 14. By the movement of the tie rod 11 of the valve 9 back and forth the valve 9 moves away and to the seat 10 of the valve 9, thus interconnecting and separating the pressure chamber 3 and the barrel 8.

(21) The pressure chamber 3 is made of steel, has the shape of a hollow cylinder capped on both ends, with the volume of 50 ml and is fitted with the supply 6 of pressurized gas, through which pressurized gas constantly flows from the canister to the pressure chamber 3. One of the basis of the hollow cylinder of the pressure chamber 3 is comprised of the seat 10 of the valve 9 with the circular shape with a centrally positioned opening made of rubber. The opening of the seat 10 of the valve 9 is closely fitted by the projectile opening 29 of the barrel 8, thus interconnecting the pressure chamber 3 and the barrel 8. The other basis of the hollow cylinder of the pressure chamber 3 is formed by a steel wall 30 with a central opening—port 5 for mounting the tie rod 11 of the valve 9. Through the port 5 the steel tie rod 11 of the valve in the shape of a capped hollow rod passes to the pressure chamber 3. The end of the tie rod 11 positioned in the pressure chamber 3 is fitted with the valve 9 having the shape of a cylinder made of rubber. The diameter of the valve 9 is greater than the central opening in the seat 10 of the valve 9 and the valve 9 fits closely to the central opening of the seat 10 of the valve 9 as a cork.

(22) Onto the tie rod 11 of the valve 9 projecting from the pressure chamber 3 the spring 15 of the striker 14 is put on, the diameter of which is greater than that of the tie rod 11 of the valve 9. Then on the tie rod 11 of the valve 9a steel striker 14 having the shape of an annulus is put on, which tightly fits to the spring 15 of the striker 14. The inner diameter of the striker 14 is greater than that of the tie rod 11 of the valve 9 and smaller than that of the spring 15 of the striker 14. The outer diameter of the striker 14 is greater than the diameter of the spring 15 of the striker 14. Onto the tie rod 11 of the valve 9 is then put on a stop 13 of the striker 14 having the shape of an annulus made of steel that is welded onto the tie rod 11 of the valve 9. The stop 13 of the striker 14 has the inner diameter greater by 1 mm than that of the tie rod 11 of the valve 9 and the outer diameter greater than the inner diameter of the striker 14. Before firing it is necessary to compress the tie rod 11 of the valve 9 in the direction of firing into the seat 10 of the valve 9 thus closing the connection between the pressure chamber 3 and the barrel 8. The pressure chamber 3 connected to the supply 6 of pressurized gas immediately fills with pressurized gas. Then it is necessary to displace the striker 14 against the force of the spring 15 of the striker 14 thus compressing the spring 15 of the striker 14.

(23) For firing it is necessary to release the striker 14, which also release the spring 15 of the striker 14, throwing the striker 14 towards the stop 13 of the striker 14 in the opposite direction of firing. The striker 14 strikes the stop 13 of the striker 14 and thanks to the kinetic energy transferred to the striker 14 by the spring 15 of the striker 14 the tie rod 11 of the valve 9 is carried along with the striker 14 stricken by the stop 13 of the striker 14 in the direction opposite to that of firing. The moving tie rod 11 of the valve 9 pulls away the valve 9 closely fitting to the seat 10 of the valve 9, thus opening the mutually connected pressure chamber 3 and the barrel 8. Pressurized air from the pressure chamber 3 flows around the valve 9 and the seat 10 of the valve 9 into the barrel 8, by which mock ammunition is fired.

(24) For live firing, it is necessary to insert the projectile 24 into the projectile opening 29 of the barrel 8. Upon firing, the projectile 24 is fired out of the barrel 8 utilizing the full force of pressurized air flowing from the immediately neighbouring pressure chamber 3.
