CHANNEL OF OPPOSITE FLOWS OF MULTIFLOW HYDRAULIC ACTUATOR Russian patent published in 2014 - IPC E02F9/22 F15B13/00 

FIELD: machine building.

SUBSTANCE: invention refers to machine-building hydraulics, and namely to hydraulic actuators of mobile machines and hydraulic plants of cyclic action with several actuating mechanisms. The invention proposes a channel of multiflow hydraulic actuator, which is intended for supply of a working liquid flow to pressure cavities and consists of several in-series connected double flow cavities having the possibility of disconnecting their inlets and outlets. Besides, on the flow inlet side, each double flow cavity is connected to the corresponding pressure cavity. Besides, in ties between pressure and overflow cavities there additionally installed are check valves directed with their outlets to pressure cavities. And outlets of double flow cavities are connected through inlets of check valves to the corresponding pressure cavities. Besides, the outlet of the last double flow cavity serves as an inlet for the other flow.

EFFECT: proposed invention allows supplying two independent flows via one hydraulic channel with several pressure cavities, as well as simplifying a hydraulic actuator and reducing dimensions of hydraulic equipment.
