Abstract
A lifting apparatus comprising a counter bearing (8) provided with a first recess (9), having a conical bearing surface (10), and an actuator unit comprising an actuator (6) whose axial extension is dependent upon an actuating signal. The actuator unit has a shoulder which is formed in an area of the actuator unit which faces away from the output and which has a domed surface (11). The domed surface (11) of the actuator unit rests upon the conical bearing surface (10) of the counter-bearing (8). The injection valve comprises said lifting device and an injector needle which is coupled to the lifting apparatus on the output side thereof and which prevents the flow of fluid through the injector nozzle when closed and otherwise releases it.
