Abstract
An improved pressure regulator for use with automotive engine fuel pumps wherein the ball is constrained for motion in a cage within the inlet chamber. The cage is made up of three simple cylindrical pins press fitted into an end cap. The inlet chamber is oversized with respect to the maximum dimensions of the caged ball array. In this manner, upon opening of the ball off of its seat, virtually no impediment to full flow of the maximum fuel pump capacity through the regulator is achieved.
