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 cage is mounted on and movable with the diaphragm and a spring within the first chamber yieldingly urges the cage toward the valve seat. The cage supports a pair of plates which retain a valve ball. The first plate has an opening through which a portion of the ball projects and a second plate retains the first plate and the ball within the cage. The first plate is movable transversely to provide for proper centering of the ball in the valve seat. A light spring extends between the cage and the ball to urge the ball against the first plate. |
