METHOD AND SYSTEM WITH MEDIUM UNDER PRESSURE WITH CONTROLLER Russian patent published in 2018 - IPC F15B1/02 F15B11/36 F15B21/14 

FIELD: machine building.

SUBSTANCE: method and system with a medium under pressure comprising: at least one hydraulic actuator (23) or a hydraulic actuating unit, by means of which total forces (Fcyl) acting on the said load are generated; at least one working chamber (19, 20, 21, 22) operating as per the principle of displacing and located inside the said hydraulic actuator or hydraulic actuating unit; at least one high-pressure charge circuit (HPi, HPia), which is the source of hydraulic power; at least one low-pressure charge circuit (LPi, LPia), which is the source of hydraulic power; control circuit (40), through which at least one of the aforementioned high (HPi, HPia) and low (LPi, LPia) pressure charge circuits can be connected in turn to at least one of working chambers (19, 20, 21, 22); herewith each working chamber (19, 20, 21, 22) is able to generate force components (FA, FB, FC, FD), which correspond to the pressures of charge circuits (HPi, HPia, LPi, LPia) connected to a specified working chamber, and each force component generates at least one of the aforementioned total forces separately or together with the force components produced by the other working chambers of the specified hydraulic actuator or hydraulic actuating unit. Control circuit of the system uses a controller.

EFFECT: reduction of energy losses.
