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: In one aspect, a pressure regulating valve assembly is provided. The valve assembly includes a housing having a fluid inlet and a fluid outlet, a sleeve positioned within the housing, and a spool at least partially positioned within the sleeve. The spool includes an outer surface having a shoulder, and the spool is configured to translate within the sleeve between a closed position and an open position. The valve assembly further includes a cap coupled to the sleeve and surrounding at least a portion of the spool, and the cap includes an inner surface with a flange extending therefrom. In the closed position the spool shoulder abuts against the cap flange to define a sealed metering edge. In the open position the spool shoulder is spaced from the cap flange to unseal the metering edge and define a metering window to facilitate fluid flow therethrough to the fluid outlet.
