Patent ID: 8671912

Claim:
An injector for injecting fuel into a combustion chamber of an internal combustion engine, the injector having an injection valve element, which is adjustable in an axial direction between a closed position and an open position and which is triggerable by means of a control valve that has a control valve element, which control valve element is adjustable by means of an actuator between a closed position and an open position and which in the closed position is at least approximately pressure-balanced, the control valve element embodied as a sleeve and having a sealing line, which in the closed position of the control valve element cooperates with a control valve seat in sealing fashion, and which in the open position the sealing line is lifted from the control valve seat and thus enables fuel flow from a high-pressure region into a low-pressure region of the injector, the control valve element having a support region which protrudes past the sealing line in a radial direction toward the high-pressure region, wherein in the sleeve, a pressure pin in one or more parts that is separate from a valve piece having the control valve seat is received in the sleeve, and that the support region is disposed on an inside circumference of the sleeve axially between the pressure pin and the control valve seat.
