The delivery valve is mounted on the distributive head of injection pump. The valve spring and delivery valve are mounted in the delivery valve holder. The surface of the delivery valve seat is made with high precision. Delivery valves are responsible to separate the high-pressure circuit between the pressure line and the pump plunger. Right after the fuel injection, the nozzle section is adjusted to a specified pressure. That's how the exactly timed closure of the nozzle is secured and undesired dripping is prevented.

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.

China-Lutong offers delivery valves of highest precision, perfectly designed to control the internal pressure in the injection pump optimally. We produce a wide range of elements, delivery valves and nozzles for fuel injection systems for diesel engines having the following applications: passenger cars, trucks, tractors, agricultural and earthmoving machines and marine engines.

We manufacture new delivery valves for all types of pumps: A, P, and Marine.

A precise manufacture and a strict control of the working schedules are peculiar to our products.
