Injector

Abstract

Abstract An injector (10) is designed so as to receive a cartridge (11) containing an injection liquid (12). This cartridge can be displaced in the proximal direction in the injector counter to the force of a restoring spring (157). A longitudinally displaceable plunger (80) is loaded in the proximal direction by a spring (53), can be displaced in the injector between a proximal terminal position and a distal terminal position, and has a threaded spindle (19) which is guided in the screw thread (17) of an adjustment member (15), serves to act upon a piston (23) provided in the cartridge (11) and to which a guide member (67) is allocated, which is connected thereto so as to be fixed against rotation but freely displaceable axially. In the distal terminal position of the plunger (80), this guide member (67) is rotatable relative to the housing (100) of the injector (10), but not in the proximal terminal position. <IMAGE>
