Abstract
A fuel pressure regulator assembly comprising a housing, a diaphragm separating the housing into a first and second chamber. The housing has a radial inlet extending to the first chamber and a connector having an axial outlet is mounted in the housing and extends axially into the first chamber. The connector supports a sealing ring. The diaphragm supports a valve member that is adapted to engage the sealing ring, and a spring in the second chamber urges said valve member against the sealing ring. The fuel pressure regulator assembly includes provision for increasing the fuel regulation pressure by varying the effective diaphragm area.
