The main component of the injector is the needle valve coupling, which is composed of needle valve and needle valve body.
The needle valve is preloaded by spring.
When the oil pressure on the pressure cone of the injector needle valve exceeds the pre-tightening force of the injector spring, the needle valve opens and the high-pressure fuel sprays into the cylinder atomization from the nozzle hole. The fuel pressure is called the valve-opening pressure.
When the oil pressure on the cone of the injector needle is lower than that of the starting valve, the needle valve is closed.
