Abstract: A pump housing includes an integral vent flow path extending between a low-pressure region and the reservoir. The vent path provides fluid communication between the downstream side of a throat seal dividing the low-pressure region from a high-pressure region and the reservoir. Lubricant flows through the vent path from the reservoir to the low-pressure region to provide lubrication to the throat seal.

Abstract: A changeover valve for a single line parallel lubrication system includes a base housing, a first housing, and a second housing, which are distinct and separable units arranged to provide direct fluid communication between base housing, first housing, and second housing fluid channels. The base housing includes a plurality of fluid channels. The first and second housings each include a spool mounted in a cylindrical bore and hydraulically displaceable between ends of the cylindrical bore and a plurality of fluid channels fluidly connected to the cylindrical bore. The first and second housings are configured to mate with the base housing in a fluid seal. At least one of the base housing, first housing, and second housing includes and a relief valve in fluid communication with one or more of the plurality of base housing, first housing, and second housing fluid channels.

Abstract: A sealing assembly includes retaining clips fit within grooves in a throat disposed between a fluid chamber and a working fluid cylinder. The retaining clips define individual seal glands, and seals and spacers are disposed within the seal glands. A piston rod passes through the throat seal, and the throat seal provides a seal against lubricant pressure from inside the fluid chamber and working fluid pressure from inside the working fluid cylinder.

Abstract: A cartridge injector cooperates with internal features of a manifold to form a complete injector assembly. The cartridge injector includes a poppet that translates within a central passage of an injector body to distribute fluid between an inlet region and an outlet region of the central passage. A piston reciprocates relative to the injector body, blocking and unblocking the inlet region, or outlet region, of the central passage to meter a volume of fluid delivered to an outlet of the manifold.
