DISCRETE HYDRAULIC SYSTEM Russian patent published in 2014 - IPC F15B1/02 F15B11/12 

FIELD: machine building.

SUBSTANCE: system comprises a hydraulic amplifier, by means of which summary forces are generated, acting at a load, at least one working chamber operating in accordance with a displacement principle and located in the specified hydraulic amplifier, one circuit of make-up of high pressure and one circuit of make-up of low pressure, a control circuit, by means of which one of the working chambers may be connected in turns to one of the above circuits of make-up of high and low pressure, at the same time the control circuit comprises for each pre-determined chamber the controlled interfaces of control, by means of which connection to the circuit of make-up of high pressure or low pressure may be opened or closed, besides, each working chamber may generate power components, which correspond to pressures of make-up circuits connected to the specified working chamber, and each power component creates at least one of the above summary forces, separately or jointly with the power components, generated by other working chambers of the specified hydraulic amplifier.

EFFECT: reduced energy losses.
