FIELD: armored machinery. ^ SUBSTANCE: proposed hydraulic drive is designed for electrohydraulic servo systems, including guidance and stabilization systems. Proposed torque hydraulic drive includes double-flow fixed delivery hydraulic pump, electrohydraulic power amplifier, actuating hydraulic motor, make-up hydraulic tank, check and remote controlled valve, inputs of check and remote controlled valves being connected with second pressure space of hydraulic pump, output of check valve being connected with first pressure space of hydraulic pump, output of remote-controlled valve being connected with make-up hydraulic tank. In proposed hydraulic drive, use in made of double-flow hydraulic pump. One flow of pump is used at all operating duties of actuating motor, and second flow is connected to first flow only for a short period, when speed of actuating motor exceeds threshold value. ^ EFFECT: reduced power consumption of electric motor of hydraulic pump. ^ 1 dwg
