摘要
<p>A fuel pressure regulator valve comprises a housing constructed from plural metal stampings and containing a diaphragm assembly which divides the housing into a control chamber and a fuel chamber. The housing is shaped to contain integral grooves for O-ring seals so that the O-rings stay on the valve when it is removed from its mounting socket in a fuel rail. Two of the stampings partially define the fuel chamber and are joined by means of a crimp formed in one. The other of the two has a hardness greater than that of the one to facilitate its press-fit engagement with the valve seat tube. The crimp is below the upper O-ring seal so that the crimp provides an entirely satisfactory joint. Each O-ring is located within its groove with the aid of a spacer also disposed in the groove.</p>
