INIETTORE DI CARBURANTE PER UN MOTORE A COMBUSTIONE INTERNA

摘要

The injector has a valve pin (4) actuated by a actuating module and forming a valve with a valve plate (5) that surrounds the valve by forming a valve seat (20). The valve is connected to a control chamber (10) by an output channel (16) integrating a throttling element to control a piston i.e. injector needle (11). The valve seat is arranged to minimize slipping of parts. The valve seat is formed by a shoulder (8) on the valve pin and a seat forming surface (19) on the valve plate.
