Abstract: A dose setting device for a delivery system has a piston rod (6, 9) which successively presses a piston (2) into a cylinder ampoule (1). Doses are set by rotating a second part (9) of the piston rod (6, 9) in relation to a first part (6). The two parts are connected by mating threads so that the total length of the piston rod (6, 9) is increased proportional to the angle of rotation, and a point (18) on the second part is moved away from a stop position fixed in relation to a housing (5) The set dose is delivered when the point (18) is moved back to the stop position. The first part (6) can be axially displaced but not rotated in the housing (5), and the second part (9) can both rotate and be axially displaced. The first part (6) is maintained in abutment with the piston (2) and the second part (9) is coupled to be rotated by a dose setting wheel (20).
