Abstract:
A pressure-regulating valve assembly includes a sleeve body and a spool. The sleeve body has an interior surface and a sense port. The spool has an external surface and is slideably received within the sleeve body such that the external spool surface and the sleeve body interior surface define therebetween a plurality of sleeve body chambers. A first of the sleeve body interior chambers is a deadheaded chamber in fluid communication with the environment external to the sleeve body through the sense port for controlling pressure of fluid traversing the pressure-regulating valve assembly.
