摘要

The injection device (1) has a valve seat (2), a valve closing element (3), an actuator (4) for actuating the valve closing element, a guide housing (5) for guiding the valve closing element and an actuator housing (6), which is arranged outside of the guide housing. The guide housing is protruded partly from the actuator housing. A sealing element (7) is provided, which has three sealing areas (7a,7b,7c) to seal the guide housing, actuator housing and a component part (9), into which the injection device is embedded.
