Abstract
An injection device is disclosed wherein a dose can be set by rotating a dose setting member, whereby a push button is elevated from one end of the device a distance proportional to the set dose from a position fixed relative to the housing, and wherein the set dose can then be injected by pressing the push button back to its non-elevated position, through which motion a screw will move approximately the same distance or a smaller distance. The invention provides a method of reducing the dose force and/or the push-button movement during injection.
