  • Patent number: 9233205
    Abstract: An injection device (2) comprises a housing (4) in which a receiving chamber (6) is provided for an injection mechanism (8) having an injection fluid container (10) that can be pressed out by means of an injection plunger (12). The injection device (2) further comprises an actuating device (18) that can be driven for automatically pressing out the injection fluid container (10), wherein said actuating device can be displaced between an insertion/removal position outside of the receiving chamber (6) and an injection position within the receiving chamber (6), wherein the actuating device (18) is spaced by a release distance (d) from the receiving chamber (6) in the insertion/removal position. A contact mechanism (22) is provided, by means of which the actuating device (18) can be brought into a stop position in which an actuating stop (26) of the actuating device (18) contacts the injection plunger (12) and in which an injection volume adjustment (28) is automatically actuated.

  • Patent number: 8641669
    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.
