FIELD: electrohydraulic follow-up systems. SUBSTANCE: proposed hydraulic drive comprises hydraulic amplifier including hydraulic pump and electrohydraulic power amplifier actuating hydraulic motor with two spaces, and make-up hydraulic tank. Hydraulic drive has also OR valve and pressure regulator. Inputs of OR valve are connected with spaces of actuating hydraulic motor, and output is connected with control input of pressure regulator whose regulating input is connected with delivery space of hydraulic pump. EFFECT: improved reliability of hydraulic drive. 1 dwg |
