Abstract (en)

[origin: EP2267295A2] The injector has a valve piston (27) including a pressure piece (29) at a control valve-sided end of the piston, where the pressure piece acting on a valve bolt (40) in an axial direction. The piston is surrounded by a low-pressure chamber (30) and is arranged in a valve chamber (34). A hydraulic connection is opened or closed from the valve chamber to the low-pressure chamber by a valve seat (45). A stop is formed at a valve body (15), and limits lifting of the piston. The piston with a counter surface (61) strikes against the stop in an opened condition of the valve seat.
