Injection Pump Delivery Valves

Thedelivery valveis mounted on the distributive head ofinjection pump. The valve spring anddelivery valveare mounted in the delivery valve holder. The surface of thedelivery valveseat is made with high precision.Delivery valvesare responsible to separate the high-pressure circuit between the pressure line and thepump plunger. Right after thefuel injection, thenozzlesection is adjusted to a specified pressure. That's how the exactly timed closure of thenozzleis secured and undesired dripping is prevented.

Main Function

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

2. Figure 19-24 illustrates the sucking action that occurs at thedelivery valvepiston 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 thedelivery valvetherefore effectively reduces the fuel pressure in the injection tube at the end of injection.
