<p>A fuel pre sure regulator valve of the type commonly used in automobile fuel injection systems. The invention relates to improved retention of the valve element within the mount that is carried by the diaphragm assembly. The valve element is a truncated sphere and the retention is by means of a circular washer that fits into a circular recess formed in the mount around the cavity that contains the sphere. The truncated circular face of the sphere protrudes through the washer so that it can coact with the valve seat. The inside diameter of the washer is closely controlled and this controls the allowable travel of the sphere within the cavity. The washer is retained on the mount by crimping the edge of the circular recess over the outside diameter of the washer.</p> |
