An original injection unit has a casing (112) and a section forcing the injected fluid from a vessel (118). It is moved by the operating section (170) which travels longitudinally in the device between end positions. There is a position-dependent connection (166) between the two, which is deactivated in the far end position of the operating section. In a region following the far end position of the operational section, it is activated. |
