Description

The rum is fitted with an impact element 6, spring-loaded in the axial direction, a spring 7, which encloses the rod 8, which is part of the impact element 6. The spring 7 is located between the impact element 6 and the heat engine 9, which is connected to the actuator 10, the latter with the help of a cam trailer 11 is associated with a ball screw mechanism 12. In case 1, an annular cylinder 13 is provided with an annular piston 14 mounted therein, which together with the ball screw mechanism 12 constitutes a rotational movement mechanism.

The piston 14 interacts with the cylinder 13 by means of a slit joint 15. In the housing 1, a combustion chamber consisting of two cylindrical cavities 16 and 17 is provided, inside which there is a striker head 18, spring-loaded in the axial direction spring 19 and interacting with the trigger 20 through the latch 21. The gas flow from the cylinder 5 to the cylinder 13 is controlled by using a disc valve 22 installed in the housing 1, which interacts with the trigger 22a, and this flow flows through the channels 5 made in the body of the cylinder 5 23.

The pump 4 (see Fig. 3) is a cylinder 24 in which a piston 25 is installed with a rod 26, but is spring loaded in the axial direction 27. A cylinder 28 has holes 28, 29 and 30, and a longitudinal groove on the piston 25 31, having three lateral branches 32, 33 and 34, the opening 28 is connected through a check valve 35 to the reservoir 3, the cross branch 33 is connected to a longitudinal groove 36 and through this groove to an opening 29, which is connected through the check valve 37 the combustion chamber 38, the cross branch 34 is connected with the hole 30, the cat Ooe goes into the atmosphere. Pump 4 is equipped with an adjusting screw.

The mechanized tool (see Fig. 2) was also spagged with a spring clamp 39 and a safety device made in the form of a safety trigger 40 coupled to a lever 41, which through groove 42 communicates with oil 43, interacting with an anvil 9, and springs 44 and 45 and the stem 8 is made in the outwardly truncated cone 46.

The tool works as follows.

When the trigger 20 is pressed, the retainer 21 releases the striker head 18, which will be moved by the spring 19 into the cylindrical cavity 16 filled with the working fluid, the latter is subjected to high compression, which will lead to a sharp increase in temperature and cause the working medium to explode. As a result, the striker face 18 will be moved to the outgoing polishing by the action of high pressure, and the impactor 6 will move in the opposite opposite direction, compressing the spring 7 so that the rod 8 strikes the anvil

9, and from the anvil 9 a blow will be given to the executive body 10.

When the striking element is moved, 6 hectares enters the cylinder 5. When the trigger 22a is pressed, which opens the valve 22, the gas flows through the channels 23 and 22 into the cylinder 13, as a result of which the splitting 14 moves, driving the rotational movement mechanism, which cam locking clutch 11 transmits rotation to the executing body 10. When a certain torque value is reached, the clutch 11 is automatically turned off, thereby eliminating tool breakage.

Prn pressing the mechanized tool shown in FIG. 2, the anvil 9 moves and enters into contact with the impact element 6, which also begins to move, releasing the spring retainer 39, as a result of which the impact member 6 under the action of spring 7 abruptly moves and enters the cylinder 5 filled with the working fluid, thereby compressing and explosion of the working body. The gases formed in this way are discharged in the direction of compression of the spring 7, the impactor 6, which strikes the anvil 9 and is fixed by the spring clamp 39 in the upstream position. Through the opened channels 23, the gas enters the cylinder 13 and activates the rotational movement mechanism.
