A distance is defined between the fixing element 22 and the rotation element 20, and the rotation element 20 has a positioning trench 202 defined in an end thereof facing the fixing element 22, wherein the intake room 111 has a first channel 110 communicating with the accommodation chamber 101 downward, a drive valve 23 screwed with a defining segment 231 of the fixing element 22 from the intake room 111 via the connection orifice of the fixing element 22, wherein after the drive valve 23 and the defining segment 231 are connected, a first spring 25 is received in the intake room 111 beside the drive valve 23, and a second spring 21 abuts against the defining segment 231 and is received in the positioning trench 202 with respect to the fixing element 22, such that the second spring 21 contacts with the defining segment 231 and the positioning trench 202 with respect to the fixing element 22, wherein an elasticity of the second spring 21 is more than an elasticity of the first spring 25 so that a pressure of the intake room 111 is small, the second spring 21 pushes the defining segment 231 to actuate the drive valve 23 to move toward and turn on the intake room 111, when the pressure of the intake room 111 increases to a predetermined value and the elasticity of the first spring 25 is more than the elasticity of the second spring 21, the defining element 231 is urged to drive the coupling element 23 to move toward the rotation element 20, thus producing air tightness. An air conducting trough 112 surrounds around the fixing element 22, and the body 10 further includes a second channel 113 defined above and communicating with the air conducting trough 112, and the second channel 113 is also in communication with the control valve 30 via the air guide room 121.
[0030] FIG. 7 is another cross sectional view taken along the line A-A′ of FIG. 2. FIG. 8 is another cross sectional view sectional view showing the operation of a part of the gas cylinder magazine M. The second channel 113 of the gas cylinder magazine M moves into the control valve 20 via the air guide room 121, wherein the body 10 further includes a threaded orifice 13 defined therein beside the air guide room 121, communicating with the air discharge chamber 122 upward, and configured to screw with the control valve 30. The control valve 30 includes a cylinder 32 screwed in the threaded orifice 13 and connected with the air guide room 121, wherein the cylinder 32 has an air orifice 321 defined on an intermediate section thereof and communicating with the air discharge chamber 122 upward, the intermediate section of the cylinder 32 is stepped and has a stepped rod 31 received therein, wherein a profile of the stepped rod 31 mates with a profile of the cylinder 32, and the stepped rod 31 has a protrusion 311, a closing segment 312, and a stop portion 313, a driving spring 33 is fitted on the stepped rod 31, abuts against the protrusion 311 and the cylinder 32, and pushes the rod 31 to move outward. The closing segment 312 is configured to limit a movement of the cylinder 32, and the stop portion 313 is pushed by the driving spring 33 to contact with and close the cylinder 32.
[0031] When the air gun is triggered, as shown in V1 of FIG. 5, the axis of the pressure valve V is intersected with the axis of the high-pressure gas cylinder 40 so that the pressure valve V moves horizontally. When the pressure of the intake room 111 is small, the second spring 21 pushes the defining segment 231 to actuate the drive valve 23 to move toward and turn on the intake room 111, and the high-pressure gas AF1 is forced by the drive valve 23 to flow into the air guide room 121 from the first channel 110 via the air conducting trough 112 and the second channel 113, thus increasing the pressure of the intake room 111. Referring to V2 of FIG. 6, when the pressure of the intake room 111 is increased to the predetermined value and the elasticity of the first spring 25 is more than the elasticity of the second spring 21, the defining element 231 is urged to drive the coupling element 23 to move toward the rotation element 20 and to stop the high-pressure gas AF2, thus inflating the gas. As illustrated in S of FIG. 8, when the gas cylinder magazine M is received in a handle of the air gun, the control valve 30 is started to drive the rod 31 to move to the air guide room 121, and the closing segment 312 is opened so that the high-pressure gas of the air guide room 121 is inflated to air discharge chamber 122 via the air orifice 321 of the cylinder 32, thus shooting the BB bullet.
[0032] Accordingly, the gas cylinder magazine M of the present invention has advantage as follows: [0033] 1) The axis of the pressure valve V is intersected with the axis of the high-pressure gas cylinder 40 so that the pressure valve V moves horizontally, and the high-pressure gas of the air gun is not pushed by the spring and the valve to control the pressure of the air gun accurately. Preferably, the elasticity of the second spring 21 is more than the elasticity of the first spring 25 so that the switching of the air inflation and airtightness produce exactly and quickly, thus shooting the BB bullet from the air gun at a high speed. [0034] 2) When inflating the gas to the air gun in various areas, temperatures and pressures, different pressures of the air gun produce. For example, when inflating the gas to the air gun at a high temperature, the pressure of the air gun increases. While inflating the gas to the air gun at a low temperature, the pressure of the air gun is insufficient. The pressure valve V of the gas cylinder magazine M is adjusted by the rotation element 20 to drive the second spring 21 to push the defining segment 231, and the drive valve 23 is actuated by the defining segment 231 to control the pressure of the intake room 111 to reach an airtight pressure value based on the using requirements exactly. Preferably, the pressure valve V is received in the gas cylinder magazine M horizontally to reduce a size of the gas cylinder magazine M and to adjust the pressure of the air gun.
