HYDRAULIC PULSATOR Russian patent published in 1995 - IPC

FIELD: working metals. SUBSTANCE: displacing hydraulic mechanism is constructed as a housing having working space, rotor, and working member. The actuating member constructed as a hydraulic cylinder having returning spring is coupled with the displacing mechanism through the delivery passage. The displacing hydraulic mechanism has pump, hydraulic motor, and suction-drain passages and is provided with the internal hydraulic distributor mounted for permitting synchronous rotation with the rotor and baffle made up as a roller provided with a flat. The working member is made up as a blade with cylindrical surface mounted to permit interaction with the roller and to define pump and hydraulic motor chambers inside the housing. The chambers are in communication with the pump and hydraulic motor passages respectively. The sucking passage is made in the housing in the middle part of the working chamber. EFFECT: improved design. 6 cl, 5 dwg
