Abstract
A driving and dosing device for an injection device includes: a housing, a dosing element gripped by a user, an actuating element actuable by the user to discharge the set dose, a propulsion element for acting on a piston to discharge the set dose, a spring configured to act between the propulsion element and an abutment, which is preloaded so as to discharge a maximum dischargeable product quantity in a plurality of individual discharges, a rotation element configured to rotate relative to the housing and a clutch configured for releasably engaging the rotation element. Releasing the clutch permits the rotation element to rotate relative to the housing when the actuating element is actuated, blocks the rotation of the rotation element relative to the housing when the actuating element is released, and by rotation of the rotation element, the spring is permitted to move the propulsion element in the discharge direction.
