Abstract: A coupling mechanism for a medication delivery device includes a first part axially fixed relative to a housing and rotatable around a longitudinal axis of the first part, the first part having a gearing engagement to a second part arranged along the longitudinal axis, the gearing engagement having a first frictional resistance. The second part axially moveable along the longitudinal axis, and directly or indirectly in a friction fit engagement with the housing, which has a second frictional resistance. The first frictional resistance being below the second frictional resistance such that a rotation of the first part in a first direction axially longitudinally moves the second part away from the first part and a rotation in a second direction, opposite to the first rotation direction, reduces the axial distance between the first and second part and/or axially moves the second part into coupling abutment with the first part.

Abstract: Drive and dosing devices for injection devices are disclosed. An embodiment may include a threaded piston rod moveable in a dispensing direction for dispensing a product. A rotation member may be operatively connected to a stop limiter and threadably engaged with the piston rod. Rotation of the rotation member may cause the piston rod to move in the dispensing direction. An embodiment may include a dose knob rotatable for changing a dose. The device may further include a stop element threadably engaged with the piston rod and having a catch. The dose knob may be coupled with the stop element such that during increase of a dose, the stop element is screwed toward the distal end of the piston rod and the catch is moved towards the stop limiter. The stop element prevents increasing a dose when the catch abuts the stop limiter.
