FIELD: impact action devices engineering.
SUBSTANCE: device has barrel with upper and lower covers, hydraulic drive including piston hydraulic engine with a clamp, electro-hydraulic distributor, switching mechanism, firing pin having hollow tail piece, spring for accumulating energy. Construction of clamp allows compression of spring when firing pin is raised and disconnection of firing pin without reactive forces. Construction of switching mechanism prevents effect from hydro-impacts and vibrations when reversing main hydro-flow of engine at high frequency of activations due to use of connecting plate and electronic-electric amplification block and sending signals by means of Hall sensors onto inductive coils of distributor, as well as use of pressing cover, steel inserts for fixing guides of fast-wear bushings.
EFFECT: more reliable construction, lesser laboriousness of maintenance, higher durability of device.
