    A hydraulic percussion machine, comprising a body carrying hydraulic passages and valves, and having a gas-filled, hydraulic pressure accumulator for storing the stroke energy which accelerates a piston to strike against a tool. The percussion machine has a separate hydraulic stroke standardizing circuit by action of which the piston stroke is independent of the liquid pressure in the high pressure line supplying the machine and of the volumetric flow.

    completely in the form of a spring-loaded spool with an annular groove in the middle part, periodically communicating with the pressure chamber 4. Channel 19 communicates the podzol-shaped cavity of valve 13 with the pressure chamber 4, and channel 10, made in the housing in the form of a hole, periodically reports the working chamber 7 with a damping 9. The damping chamber 9 is located in the axial channel 2 from the end of the larger stage of the impactor element 3 and faces the striker 6, the damping chamber 9 communicates with the main valve 5 of the pressure channel 20. 1 sludge.
    The invention relates to hydraulic shock mechanisms and can be used in construction and mosh works.
    The purpose of the invention is to increase reliability due to the effect of the alignment circuit on the piston stroke, due to which the stroke does not depend on the pressure in the pressure line,
    The drawing shows a hydraulic shock mechanism, a longitudinal section.
    The hydraulic percussion mechanism includes a housing 1 with a step-by-step channel 2, concentrically located in it, an equivalent in shape to a stepped axial axis of the channel 2, a shock element 3, the butt of the small stage of which and the housing 1 form a shock Kai-iepa 4j communicating with the main valve 5 The firing pin 6 is located at the other end of the impactor 3, Chambers 7 and 8 are compensated for the working and reverse chambers, the damper chamber 9 is connected by channel 10 with the compensation chamber 7 of the pressure accumulator 11 with the chamber 12, with The valve is permanently connected with the stepped axial channel 2, the valve cavity 13 controls the channel 14 with the pressure accumulator 11, and the channels 15 and 16 correspond to the pressure 17 and the drain 18 lines. The pressure accumulator 11 is coaxially placed and permanently communicated with the impact chamber 4, the control valve 13 is designed as an axially spring-loaded spool e by an annular groove in the middle part, the cavity between which and the case 1 is preassigned for periodic communication with the shock chamber 4. In case 1 fulfilled
    channel 14, jointly through the channel 19 to the podzolotnik about the cavity and pressure accumulator 11 with a shock chamber 4; In case 1, a pressure channel 20 and a control channel 21 are made.
    Hydraulic shock mechanism works as follows.
    Fluid from the pressure line 17 flows through the pressure channel 20 into the cavity of the chamber B of the return stroke.
    Impact element 3. moves towards battery 11 and displaces fluid from chamber 4 to accumulator 11 Liquid from chamber 7 of the working stroke through main valve 5 enters the drain line 18 When the shock link reaches its extreme position, chamber 8 is reversed through the control channel 21 with the main valve 5, which directs the high pressure fluid to the working stroke chamber 7, locking the sigil line 18, the impactor 3 starts the working stroke due to the energy received from the fluid (under pressure), akschey blunt by pressure line 17 through the main valve 5 in the working stroke chamber 7. However, most of the energy during the working stroke, the impactor 3 receives pressure from the battery t1 through the shock chamber 4. After the shock member 3 has started the working stroke, the control pressure channel 21 closes and the main valve 5 directs the pressurized fluid to the shock chamber. Then the cycle repeats.
    The control valve 13 is designed to control the accumulator pressure. Torus 11,
    If at the end of the working stroke the pressure drops below the set value, the control valve 13 connects the anal channel 14 to the channel 15 and the fluid enters the liquid space of the battery 11. If the pressure in the liquid space of the battery 11 is too large, the control valve 13 connects the channel 14 with a drain line 18. Channel 10 is intended to prevent ignition of reverse moves that can occur if, for example, impact element 3 strikes striker 6, which in turn strikes air in this case. In this case, the resistance of the object is absent, the impact element 3 travels a longer distance than usual and stops, resting against the damping chamber 9, as a result of which the upper edge of the impact element 3 has a larger dia-; meter opens channel 10 connecting chamber 7 of working stroke with damping chamber 9, impactor 3 is stopped in its lowest position, and there will be no repetition of backward strokes. In order to continue the work of the percussion mechanism, it is sufficient to rest the beater against a fixed leg, for example, a stone. At the same time, the impactor 3 rises so that the upper edge of the larger diameter section of the element 3 closes the channel 10.
