An Element consists of barrel and plunger. The plunger is precisely fitted to the barrel with very small clearance to form a perfect sealing.They should be replaced as a set.
Function:
The function of the element is to meter and deliver the metered fuel.
The Delivery Valve is seated on top of the element.
Function:
It performs the following functions:
1. It helps to assist in the rapid build of pressure in the injection line.
2. It also helps to cut the flow of fuel at the termination of fuel injection pulse.
These are Inline Pumps used for slow speed diesel engines. The Flange mounted fuel injection pump is Camoperated, spring return plunger pump of constant stroke. The fuel delivery is controlled by the angular displacement of the plunger with regulating edge according to the instantaneous output charge of the diesel engines. The angular displacement of the plunger is derived from the regulating bar acting on the plunger control sleeve.
