Abstract
A pressure relief valve includes a singular body that encloses a seat and a stationary shim, a poppet, within the singular body, that is forced against a seat by a spring attached to the stationary shim, and a pin inserted into the pressure relief valve body to lock the pressure relief valve into a housing bore. The poppet includes a nose extension that extends into a void enclosed by the seat to provide damping. The seat includes a non-threaded stepped region on its outer surface and the singular body includes a complementary stepped region on its inner surface such that when the seat is fit into the singular body, the stepped region of the seat and the complementary stepped region of the singular body interface with each other to prevent movement of the seat toward the spring. The pin includes a coating to reduce friction and galling.
