Electromechanical injection apparatus
First Claim
1. An injection apparatus (2) having a carrier housing (4), into which an injection device (8) having at least one injection fluid container (10) that is capable of being expressed can be inserted,and an actuating apparatus (12) capable of being driven along an injection direction (R) in order to activate the injection device (8) and capable of being acted on for performing at least one pricking stroke and one injection stroke by a mechanical energy storage unit (20) and an electrical transport unit (26),characterized in that the actuating apparatus (12) is driven in the injection direction (R) by a driving force of the mechanical energy storage unit (20) and the electrical transport unit (26) forms a speed limiter which acts counter to the driving force during an injection, in order to limit a stroke speed attained via the mechanical energy storage unit.

Abstract
An injection apparatus (2) has a carrier housing (4), into which an injection device (8) having at least one injection fluid container (10) that can be pressed out can be inserted, and an actuating apparatus (12) which can be driven along an injection direction (R) in order to activate the injection device (8) and which can be acted on for performing at least one pricking stroke and one injection stroke by a mechanical energy storage unit (20) and an electrical transport unit (26). The invention provides for the actuating apparatus (12) to be driven in the injection direction (R) by the driving force of a mechanical energy storage unit (20) and for the electrical transport unit (26) to form a speed limiter which acts counter to the driving force during an injection, in order to limit a stroke speed attained via the energy storage unit.
