CONTROLLER FOR HYDRAULIC PUMP Russian patent published in 2018 - IPC F04B1/06 F04B49/22 

FIELD: machine building.

SUBSTANCE: invention relates to controller for the machine, to hydraulic circuit controller and design, which operation is based on the fluid medium. Hydraulic pump 6 comprises housing 20, first and second inlet members 100a, 100b, first and second outlet members 102a, 102b. Crankshaft 4 passes inside the housing 20 and comprises axially shifted first and second cams 62, 64. “Piston-cylinder” assemblies 30, 32 first and second groups are located in the housing 20. Each of said groups 30, 32 comprises a number of “piston-cylinder” assemblies comprising working chamber with the cyclically variable volume and connected to crankshaft 4 with possibility of the motion transmission. One or more electronically controlled valves 40 connected to the first and second groups 30, 32. Controller 70 is configured to the said electronically controlled valves 40 opening and / or closing active control in each of the working chamber volume change, in order to control the fluid medium actual displacement using the first and second groups 30, 32. At least the first group 30 comprises first “piston-cylinder” assembly is coupled to the first cam 62 with possibility of motion transmitting. Second “piston-cylinder” assembly is coupled to the second cam 64 with possibility of motion transmitting. First group is configured to receive the working fluid medium from the first inlet member 100a and the working fluid medium discharge to the first outlet member 102a and the second group is configured to receive the working fluid medium from the second inlet member 100b and the working fluid medium discharge to the second outlet member 102b.

EFFECT: reducing the intended for use in vehicles pumps weight and size.
