ABSTRACT:
In a discharging apparatus (1) for in particular a single use, the complete pump stroke (11) to be performed only once is subdivided into at least two partial strokes (12,13) by a limiting device (24) which, for the end of each partial stroke, has a stop (25) to be overcome in the manner of a resilient detent. All parts of the limiting device (24) are located in such a way that the guidance of pump piston (6) on thrust piston pump (4) on the piston running path (7) is in no way impaired. At the end of the last partial stroke (13) the pump cylinder (5) mountable as a separate vessel on pump piston (6) is positively locked with respect to the remaining discharging apparatus (1) by a removal preventing means (40), so that the interior of pump cylinder (5) is no longer accessible.
