Fuel injector valve for combustion engines

摘要

The valve has a housing (1) provided with a length-adjustable nozzle needle (8) for opening and closing an injection port (16) with a nozzle seat (15). The nozzle needle with the nozzle seat is turned away from a surface (108) of the housing. A control chamber (10) is filled with fuel under high pressure and provided with a control valve (22) and a low pressure chamber (18). An end of a pressure pin (33) is provided in the control chamber, which cooperates with a surface of a force sensor (35). A control valve link (28) is formed in sleeve-shape and surrounds the pressure pin.
