HYDRAULIC SYSTEM FOR MACHINE, MACHINE AND METHOD OF CONTROLLING HYDRAULIC SYSTEM Russian patent published in 2018 - IPC B66F9/22 F15B11/08 E02F9/22 

FIELD: machine building.

SUBSTANCE: invention relates to a hydraulic system for driving the working equipment of machines. Machine comprises a first pump and a second pump for supplying hydraulic fluid to a hydraulic cylinder, and a hydraulic distributor. Hydraulic distributor has a first inlet hydraulically connected to a first constant-flow pump, and a second inlet hydraulically connected to a second constant-flow pump, a first outlet hydraulically connected to the hydraulic cylinder, and a second outlet hydraulically connected to a tank. Hydraulic distributor has a first working position, in which the working fluid pumped by the first and second pump is directed to the hydraulic cylinder, and a second operating position, in which the working fluid pumped by only the second pump is directed to the hydraulic cylinder, and the working fluid pumped by the first constant-flow pump is fed directly back to the tank.

EFFECT: simplification of the design while increasing capacity.
