Cummins Delivery Valves 131160-0620 A87(750) Ny

Main Function

1. At the end of the plunger’s upward fuel delivery stroke, the delivery valve prevents a reverse flow of fuel from the injection line.

2. Figure 19-24 illustrates the sucking action that occurs at the delivery valve piston portion which controls the residual pressure in the injection line so as to effectively improve the injected spray pattern of the fuel without fuel dribble and possible secondary injection. The sucking action that does occur at the delivery valve therefore effectively reduces the fuel pressure in the injection tube at the end of injection.

China-Lutong is known all over the diesel market for being a twenty years experienced manufacturer of Diesel Injection Spare Parts.
