摘要：
Injection device with a housing (2, 102), in which a housing (5) for an injection liquid reservoir is configured, the injection device (1, 101) having a control element (6, 106) for adjustment of an injection dose, the injection device (1, 101) having a dosing element (16, 116) which, during the adjustment of the injection dose, rotates around a central longitudinal axis (50) of the device injection (1, 101) in relation to the housing (2, 102), where the dosing element (16, 116) has a zero position (85, 185) and at least one injection position (73, 173), no dose being set in the zero position (85, 185) and a planned injection fluid dose being adjusted in each injection position (73, 173), the injection device (1,101) having a retention device (26, 126) acting between a positioning piece (20, 120) and the housing (2, 102), can Turn the positioning piece (20, 120) around the central longitudinal axis (50) of the injection device (1, 101) to adjust an injection dose, where the positioning piece (20, 120) is attached to the element of dosage (16, 116) in a fixed manner against rotation during the adjustment of an injection dose, where the positioning piece (20, 120), during the expulsion of the dose, moves in the direction of the central longitudinal axis (50 ) in relation to the housing (2, 102) and is guided in at least one longitudinal rib (52, 152) of the housing (2, 102), at least one element of being configured in the longitudinal rib (52, 152) retention (53, 153) of the retention device (26, 126) and where each injection position (73, 173) of the dosing element (16, 116) is assigned a retention position of the retention device (26, 126) , characterized in that the dosing element (16, 116) can be placed in at least an intermediate position (74) in which no dose of intended injection liquid is adjusted and because, between the dosing element (16, 116) and the housing (2, 102), a spring (82, 182) acts that , with the operating element (6, 106) not activated, returns
