ABSTRACT:
A fuel pressure regulator comprising a housing, a diaphragm dividing the housing into a first chamber and second chamber, a passage from the exterior of the housing to the first chamber, an inlet and an outlet associated with the second chamber of the housing, and a valve seat associated with the outlet. A carrier is mounted on and movable with the diaphragm and a first spring within the first chamber yieldingly urges the carrier toward the valve seat. The carrier supports a plate that has an opening therein. A valve has a hollow tubular closed end portion that projects through the opening in the plate for engagement with the valve seat and a peripheral portion that retains the valve between the carrier and the plate. A second spring is interposed between the carrier and extends into the tubular portion of the valve to yieldingly urge the valve toward the valve seat and permit relative movement between the valve and the valve seat. The opening of the plate is larger than the tubular portion of the valve and the valve is movable transversely to provide for proper centering of the valve in the valve seat.
