Abstract: The valve of a liquid fuel pressure regulator comprises a two-part construction consisting of a spherically contoured element and a stem. The spherically contoured element serves to swivelly mount the valve on the movable wall which carries the valve. The spherically contoured element comprises a hole which is on a radial to the center of the element. The shank of the stem is press-fitted to this hole to dispose the stem's flat circular head toward a seat with which the valve coacts as the pressure regulator operates. The swivel mounting compensates for misalignment and out-of-squareness of the valve travel relative to the seat and enables the head to close flat against the seat. Two embodiments are disclosed. In one, the spherically contoured element is a sphere and the hole is a blind hole drilled into the sphere. In the other, the spherically contoured element is a truncated sphere and the hole is a through-hole.

Abstract: A fuel injection system and control valve are disclosed for use with a multi-cylinder engine such as a diesel or proco type engine. The disclosed control valve, which is of the piezoelectric type, controls the fuel injection into the individual cylinders by being connected in fluid circuit between the high pressure pump and distributor which are contained in the pump and distributor assembly. The control valve contains novel features providing improvements in the system.
