Claims20
A hydraulic displacement motor, comprising:
- a valve plate coupled to at least one piston of a cylinder block, the valve plate comprising a plurality of grooves fluidly coupled to a passage comprising a valve.
A fluid displacement motor, comprising:
- a cylinder block in which a plurality of pistons oscillates;
- a valve plate comprising a central opening through which at least one of the plurality of pistons oscillates and between a first opening and a second opening, the valve plate further comprising a plurality of grooves, a first groove arranged between the central opening and the first opening, a second groove arranged between the first opening and an outer rim of the valve plate, a third groove arranged between the central opening and the second opening, and a fourth groove arranged between the second opening and the outer rim;
- and
- a valve arranged in a connecting passage coupled to an inlet port of the fluid displacement motor, the valve configured to control fluid flow to the plurality of grooves.
