Abstract: A valve includes a valve body having a valve plunger barrel formed therein and configured to be mounted to a pump head of a fuel pump, a valve plunger arranged to perform reciprocal motion with respect to the valve plunger barrel, a drive assembly configured to cause the valve plunger to perform reciprocal motion, and a spacer configured to couple to the valve plunger to perform reciprocal motion together with the valve plunger and configured to interface with the pump head. The spacer has a spacer body with first and second opposing spacer surfaces and with a central aperture extending from the first to the second spacer surface and configured to receive the valve plunger therethrough. At least one of the first and second spacer surfaces includes one or more grooves recessed into the spacer body to reduce or inhibit cavitation of the interface of the spacer and pump head.

Abstract: A pump inlet valve includes a valve body and a plunger assembly. The valve body includes a valve body cavity. The plunger assembly is arranged within the valve body cavity and includes a plunger body, a plunger barrel formed at the plunger body so as to form a plunger barrel volume, and a plunger. The plunger is configured to move within the plunger barrel to thereby allow a fluid to flow past the plunger assembly when the plunger is in an open position and to inhibit the fluid from flowing past the plunger assembly when the plunger is in a closed position. The plunger is configured to allow continuous fluid communication between the plunger barrel volume and a supply inlet, through which fluid is supplied to the pump inlet valve.
