Abstract

An injection device includes a housing having a receptacle for a vessel for holding injection fluid; an operator-manipulated element for setting an injection dose; a dosing member rotatable about a longitudinal center axis relative to the housing when setting the injection dose; a feed part; and, a latching unit acting between the feed part and housing. The dosing member has a zero position whereat no dose is set and an injection position whereat an intended dose of injection fluid is set. A spring acts between the dosing member and the housing to return the dosing member from an intermediate position to the injection position or a zero position.
