The invention relates to an injection device (1, 121, 131) having a housing (2), a longitudinal center axis (50), and a dosing device (18, 138) mounted rotatably and permanently in the direction of the longitudinal center axis (50). The dosing device (18, 138) is connected via a first threaded connection (19) to an injection sleeve (17, 97, 107, 127, 137), which is held in a rotatably fixed manner relative to the housing (2) and which is movable in the direction of the longitudinal center axis (50). The injection device (1, 121, 131) has a latching apparatus (35, 125, 135) which is effective at least upon adjusting the volume of injection liquid to be pressed out of a container (5). In order to enable latching positions of the latching apparatus (35, 125, 135) having differing distances to each other, the latching apparatus (35, 125, 135) according to the invention engages between two components of the injection device (1, 121, 131) which move relative to each other upon adjusting the volume of injection liquid to be pressed out, wherein an adjusted volume of injection liquid is uniquely allocated to each relative position of the two components to each other. |
