Beschreibung
Zusammenfassung:	A dosing system for an injection device for dispensing a dose of a product includes a housing having a longitudinal axis, a dose-setting element, a holding element and a coupling sleeve for driving a driving device for dispensing the dose. The dose-setting element, holding element, and coupling sleeve may be accommodated in the housing. To set and correct the dose, the dose-setting element and the coupling sleeve move in the direction of the longitudinal axis relative to the housing, and the coupling sleeve may be held the holding element rotationally fixed by relative to the housing. To dispense the dose, the coupling sleeve may rotate relative to the housing, the dosing system including a guide in the housing, in which guide the holding element may be displaced in the direction of the longitudinal axis relative to the housing and be guided in a rotationally fixed manner relative to the housing.
