Diesel Injection Pump Fuel Delivery Valve Model No.131160-4620 32A

Fuel delivery valve is a one-way valve. The conical part of the fuel valve is the axial seal conical surface of the valve, and the cone part of the valve slides in the pilot hole to play a guiding role. Its tail is processed with grooves, forming a cross section, in order to allow fuel to pass through. There is a small cylindrical surface under the cone of the oil outlet valve, known as the decompression ring, its role is to make the oil pressure in the high-pressure tubing drop rapidly at the end of the oil supply, in order to avoid the phenomenon of oil droplets at the nozzle hole. A reduced pressure volume is formed between it and the sealing cone. The inner chamber of the pressure nut of the fuel delivery valve is provided with a grooved reducing container. To reduce the volume of the inner cavity space, promote the rapid spray stop, limit the maximum lift of the oil valve, is its role.
