摘要：
A piston rod (7) is arranged in a body and provided with a helical element (13) and an axial element (18). A guide element which is arranged in the body and fixed relatively to the body is coupled to the helical element to guide a helical movement of the piston rod and coupled to the axial element to guide an axial movement of the piston rod. The axial movement allows a priming of the device preceding the helical movement of the piston rod.
