摘要： An injection device has a plunger for displacing a stopper in a syringe or carpule, a holder for the plunger, a drive for the axial displacement of the holder of the plunger, and a control device functionally assigned to the drive. The plunger, or at least a subcomponent thereof, relative to the holder, the holder is able to move over a limited distance relative to the plunger or a subcomponent thereof, opposing a pretensioning force, in that a sensor device is included which detects the relative position of the plunger, or at least a subcomponent thereof, relative to the holder, which comprises at least one sensor element which works together with the control device. The control device is designed such that, upon activation of the sensor element, the speed of advancement of the holder of the plunger is at least reduced.
