[0033] The device with a reciprocating motion mechanism enabling the conversion of its moment of inertia into rotational speed or rotational speed into moment of inertia according to the first manufacture version, as shown in FIG. 1-11, consists of the rotating shaft assembly 1 and the installed on it mechanism of reciprocating motion in two perpendicular directions 2. The mechanism of this motion consists of two circular discs 3 and 4 with hubs 5 and 6, tiled in parallel, of which the surfaces have 10 trapezoid notches 7 and 8 each, with two rounded sides, also separated by 10 stiffening ribs 9, made in each of the two discs and placed opposite to each other, whereby both hubs 5 and 6 of these discs are connected by means of bolts 10 and fixed to the rotating shaft 11 by means of grooves 12 in this shaft and in discs 3 and 4, and tongues 13 seated in them. Between each pair of trapezoid notches 7 and 8, there are connectors 14 of the upper ends of each pair of opposite moving arms 15, having an articulated connection with each other by means of pins 16, while the other ends of these arms are connected to two ring connectors 17 of two hydraulic actuators 18 by means of seating in profile notches 19 of each pair of these connectors and connecting them with each other using clamping rings 20, whereby all connectors 14 are equipped functional components 22, acting as a belt pulley, or functional components 23, acting as a cutting tool, a knife or a cutter, or functional components 24, acting as a weight, placed on them and connected to them by means of bolts 21. In addition, the external upper surfaces of both circular discs 3 and 4 are covered by ring guards 25 and 26. Each of the two hydraulic actuators 18 of the reciprocating motion mechanism 2 consists of a ring connector 17, a guide sleeve 27 with ring flange 28, which are float seated on the rotating shaft 11, whose opposite surfaces have recesses 29 and 30 with seals 31 between them and the shaft, whereby both of these recesses contain sleeve 32, of which both faces adhere to this connector and flange, which are connected to each other by means of 5 bolts 33, evenly distributed on their perimeter. In addition, a fixed ring piston 34 is seated and sealed on the rotating shaft 11. The external surface of this piston is flush with the internal surface of the sleeve 32 of this actuator, however both on the external surface of this shaft and on the internal surface of the guide sleeve 27 there are three guide ducts 35, evenly distributed on their perimeters, with containing grooves 36, which are also seated inside corresponding grooves 37 on the rotating shaft 11, enabling simultaneous sliding coaxial reciprocating movement of both hydraulic actuators 18.

[0034] In turn, the rotating shaft assembly 1 consists of the rotating shaft 11, having two internal ducts 39 and 40 along its rotation axis 38, and their perpendicular and connected openings 41 and 41, made on the surface of this shaft and placed under sleeves 32 and on the opposite sides of pistons 34 of hydraulic actuators 18, whereby on both ends of the rotating shaft there are seated rolling bearings 42, and besides them there are fixed sealed heads 43 and 44 with external oil ducts 45 and 46, which supply pressurised oil to both actuators through the vertical opening 47 connected to the duct 39 or directly through the duct 40. In addition, a microcontroller 48 is seated on the external surface of the guide sleeve 27 of the hydraulic actuator 18, and sensors 49 and 50 are on the surface of upper connectors 14 and moving arms 15 of the reciprocating motion mechanism, or favourably strain gauges for force measurement, which are connected to the electrical power source 52 by means of electrical wires 51.

[0035] In addition, the device based on the invention is equipped with an external microcontroller 53, in wireless co-operation with the microcontroller 48 by means of electromagnetic waves.

[0036] The device with a reciprocating motion mechanism enabling the conversion of its moment of inertia into rotational speed or rotational speed into moment of inertia according to the second manufacture version, as shown in FIG. 14, has a similar design to the device according to the first manufacture version (FIG. 1-11), and the difference between them consists only in the replacement of the rigid arms 15 of the first version with electrical actuators 54, also having an articulated connection with the connectors 14, in which the upper ends of piston rods 55 have an articulated connection by means of pins 16 with their connectors 14, while the lower ends of these piston rods are connected to two ring connectors 17 of the two hydraulic actuators 18.

[0037] In turn, the device with a reciprocating motion mechanism enabling the conversion of its moment of inertia into rotational speed or rotational speed into moment of inertia according to the third manufacture version, as shown in FIG. 15 FIG. 17 has a similar design to the device according to the first version, as shown in FIG. 1-5 and FIG. 8-11, and the difference between them consists only in the third version including only the left half of the device according to the first version, with the left disc 3 being equipped with all existing components co-operating with it. Due to this restriction, the device with a reciprocating motion mechanism enabling the conversion of its moment of inertia into rotational speed or rotational speed into moment of inertia according to the third manufacture version, as shown in FIG. 15-17, also consists of the rotating shaft assembly 1 and the installed on it mechanism of reciprocating motion in two perpendicular directions 2. The mechanism of this motion also consists of only one circular disc 3 with hub 5, of which the surface has 10 trapezoid notches 7, with two rounded sides, separated by 10 stiffening ribs 9, made in this disc, whereby the hub 5 of this disc is fixed to the rotating shaft 11 by means of grooves 12 in it and tongues 13 seated in them, whereby the external surface 56 of this disc adheres to the external surface 57 of the ring recess 58 of the rotating shaft 11. In each trapezoid notch 7 of the disc 3, moving arms 15 are placed, of which the upper ends have an articulated connection by means of pins 16 with connectors 14, while the lower ends of these arms are connected to the ring connectors 17 of the hydraulic actuator 18 by means of seating in profile notches 19 and using clamping rings 20, while all upper connectors 14 are equipped with functional components 23, acting as a cutting tool, or a belt pulley 22, or weight 24, placed on them and connected to them by means of bolts 21. In addition, the upper external surface of the disc 3 is covered by a ring guard 25. In turn, the hydraulic actuator 18 of this device also consists of a ring connector 17, a guide sleeve 27 with ring flange 28, which are float seated on the rotating shaft 11, whose opposite surfaces have recesses 29 and 30 with seals 31 between them and the shaft, whereby both of these recesses contain sleeve 32, of which both faces adhere to this connector and flange, which are connected to each other by means of bolts 33, evenly distributed on their perimeter. In addition, a fixed ring piston 34 is seated and sealed on the rotating shaft 11. The external surface of this piston is flush with the internal surface of the sleeve 32 of this actuator, however both on the external surface of this shaft and on the internal surface of the guide sleeve 27 there are three guide ducts 35, evenly distributed on their perimeters, with containing grooves 36, which are also seated inside corresponding grooves 37 on the rotating shaft 11, enabling simultaneous sliding coaxial reciprocating movement of this actuator. Besides, in this version of the device the rotating shaft assembly 1 consists of the rotating shaft 11, having an internal duct along its axis 39 and a second duct 40 in the head of the shaft, parallel to the channel 39. The internal ends of these openings are connected by perpendicular openings 41 and 41, also made in the rotating shaft 11 with the inside of the guide sleeve 27 of the hydraulic actuator 18, whereby one of these openings is on one side of the piston 34 of this actuator and the other on the opposite side of this piston. In addition, on the free end of the rotating shaft 11 there is a seated rolling bearing 42 with a fixed sealed head 44 covering its head, while both of these heads are equipped with external oil ducts 45 and 46, which supply pressurised oil to this actuator through the opening 47 to the duct 39 or directly through the channel 40. In addition, in this version of the device as well, a microcontroller 48 is seated on the external surface of the guide sleeve 27 of the hydraulic actuator 18, and sensors 49 are on the surface of moving arms 15 of the reciprocating motion mechanism, or favourably strain gauges for force measurement, which are connected to the electrical power source 52 by means of electrical wires 51.

[0038] The working principle of the first or the second version of the device based on this invention consists in supplying the oil using external ducts 45 and 46 to the control heads 43 and 44, from which it is supplied to the sleeve 32 under specific pressure through duct 39 and opening 41 made in the rotating shaft 11, which results in the hydraulic actuators 18 of the motion mechanism 2 using their guide sleeves 27 making a horizontal plane motion towards towards both discs 3 and 4, which results in the arms 15, which have an articulated connection with them, moving with the interconnecting upper connectors 14 and functional components 22 or 23 or 24 towards the guards 25 and 26 of both discs 3 and 4 to their maximum position, limited by the length of arms 15, which sets their maximum diameter. In turn, if oil is supplied to the sleeve 32 of both hydraulic actuators 18 through the duct 40 and the opening 41, the plane motion of these actuators switches to the opposite direction, which results in the arms 15 of the motion mechanism 2 moving towards the rotation axis 38 of the rotating shaft 11 to their set position, which at the same time causes a vertical, inverse motion of the upper connectors 14 with their functional components 22 or 23 or 24, which sets their minimum diameter. The working principle of the third version of the device based on this invention is also similar to the above described working principle of the first and second manufacture version.

[0039] The switch of direction of the horizontal reciprocating motion of both hydraulic actuators 18, resulting in a corresponding change of direction of the vertical reciprocating motion of upper connectors 14 with their functional components 22 or 23 or 24, causes as appropriate the conversion of the moment of inertia into rotational speed or rotational speed into moment of inertia, triggered by the change of diameter of these connectors and their functional components.

[0040] In turn, the microcontroller 48 is supplied from an external electrical power source, for example, a battery, whereby the voltage of this current is transmitted by the rotating shaft 11, for example by graphite brushes, not shown in the drawing, transferring the voltage to the sliding sleeves placed on this shaft. Sensors 49, for example strain gauges, are used to measure the strain and force of the torque, while sensors 50 are used to measure the load of the upper connector 14. In turn, the external microcontroller 53 is used for wireless communication (radio, for example Bluetooth) with the controller 48, placed on the rotating shaft 11, thus it is used to:

[0041] download the acquired data from the microcontroller 48 and sensors 49 and 50

[0042] send signals to the microcontroller 48 to control electrical actuators 54, changing the length of their piston rods 55, as well as to:

[0043] measure the rotational speed by means of a sensor, not shown in the drawing

[0044] control the pump (not shown in the drawing), supplying oil through heads 44 and 45, thus to control the position of hydraulic actuators 18 during the reciprocating motion.
