Fuel Pump Plunger and Barrel
The Plunger and Barrel assembly is found in many fuel injection systems, where a plunger reciprocates within a stationary barrel. The plunger operates by moving upwards and downwards, and its function relates to helping build up the pressure of the diesel fuel before it gets atomized into the combustion chamber. Furthermore, a constant circulation of fresh fuel flow is required to renew the fuel supply within the supply chamber, to help prevent overheating, and to prevent the accumulation of air within the system – for the reasons above, we see that the plunger function is highly important.
Different components like the in-line injection pumps, unit injectors, and unit pumps may similarly generate pressure via a pump plunger. As we can see, there are many different types of plungers and barrels – to ensure that you get the correct part with a perfect fit, please let us know your required plunger part number.
