    摘要： A high-pressure pump has a housing whose cylindrical chamber is subdivided by a piston into a fixed-volume compartment and a variable-volume compartment. An orbital crank is connected via a connecting rod to this piston to reciprocate it in the housing and thereby cyclically increase and decrease the volume of the variable-volume compartment. This variable-volume compartment is connected via a downstream conduit and a checkvalve to a supply of liquid lubricant, and to an upstream conduit and an upstream checkvalve both to the fixed-volume compartment and to the joints or bearings at the end of the connecting rod.

    摘要： A piston head assembly having an annular groove carries a substantially L-shaped cross-sectional ring. One side of the ring has a wear surface, while the other faces of the ring are slanted to provide gas access to the rear of the ring. The annular groove has matching faces whereby sticking and excessive wear is reduced.

    摘要： Methods and apparatus are provided for lubricating a piston-to-shoe interface in a hydraulic motor or pump. Piston assemblies are installed in a housing that are each adapted to receive a reciprocating drive force and are each configured, in response thereto, to cyclically move between an intake direction and a discharge direction. Each piston assembly includes a piston and a piston shoe, and the piston, the piston shoe, or both have a plurality of pockets formed in a surface that defines a piston-to-shoe interface. When the pistons cyclically move, liquid is supplied to each piston-to-shoe interface to form a hydrostatic bearing at each piston-to-shoe interface. A portion of the liquid that is supplied to each piston-to-shoe interface is selectively supplied to and from one or more of the plurality of pockets.
