Abstract: A valve includes a housing having an inlet and an outlet. A spool is fixed within the housing and defines a flow window therethrough for fluid communication between the inlet and the outlet. A piston is slidingly engaged in a piston compartment of the spool. A sleeve is slidingly engaged with the spool on an outer surface of the spool. The piston and sleeve are operatively connected for common motion along a sliding axis relative to the spool and housing between a first position in which the sleeve occludes the flow window to inhibit flow from the inlet to the outlet, and a second position in which the sleeve unoccludes the flow window to allow flow from the inlet to the outlet.

Abstract: A high pressure relief valve includes a nozzle that is received within an internal bore of a valve housing. The nozzle has a nozzle body with a bore defined by an outlet bore inner diameter that is less than an inlet bore inner diameter. The nozzle body has a nozzle face defined at the outlet end, and is defined between the outlet bore inner diameter and an outlet bore outer diameter spaced radially outwardly of the outlet bore inner diameter. The nozzle body includes a coupling feature held fixed relative to the nozzle body such that the coupling feature is not moveable relative to the nozzle body. The coupling feature is configured to couple the nozzle body to the closure sleeve that surrounds the outlet end. At least one retaining feature prevents the coupling feature from being uncoupled from the closure sleeve.

Abstract: A fluid metering valve includes a flow circuit defined by the valve and a valve member disposed in the flow circuit, the valve member having a sealing portion and configured to be moved by a solenoid between a closed position and one or more open positions. The valve includes a seat member defining one or more fluid outlets, the seat member configured to receive the sealing portion in the closed position to seal the fluid outlets, and an internal porting path defined through the sealing portion that is configured to fluidly connect a downstream side of the sealing portion with an upstream portion of the flow circuit in the closed position to reduce the effective pressure area of the valve member.
