Abstract
A regulating mechanism for maintaining a preselected pressure within the fuel rail portion of a fuel injection system of an internal combustion engine. The regulator has a cannister with a hollow interior which is divided into a biasing chamber and a fuel chamber by a diaphragm assembly. The diaphragm assembly includes a molded diaphragm having a centrally located socket containing a truncated spherical ball. Centrally disposed coaxial tubular members define concentric fuel inlet and outlet passageways communicating with the interior of the fuel chamber. The inner tubular member defines the fuel outlet passageway and has a valve seat which is normally closed by the truncated surface of the spherical ball, subject to being opened by excessive fuel pressure against the fuel chamber side of the diaphragm.
