Fuel Injector Nozzle Coupler

The injector nozzle assembly consists of the needle valve and the needle valve body. The upper conical surface of the needle valve bears the axial thrust generated by the oil pressure, causing the needle valve to lift. The lower end surface of the needle valve mates with the sealing cone surface inside the needle valve body, ensuring a tight seal within the injector chamber.

Products Description

Forklift Diesel Engine Fuel System Three Couplers:

The plunger coupler, the delivery valve coupler, and the injector nozzle coupler are the three major precision components of the diesel fuel system. The three major precision couplers wear parts, that have a great impact on the starting, power, and economy of the diesel engine.

Common faults of three couplers of forklift diesel engine:

(1) Drip oil from the injector

(2) Nozzle valve coupler bite

(3) Wear of nozzle and nozzle guide surface
