Abstract

In a discharge apparatus (1) on a basic body (8) is provided a pneumatic pump (19) and axially adjacent thereto a casing chamber (14) for receiving a magazine (15) for individual doses of a pulverulent or similar medium, whose magazine chamber (30) can be transferred into a discharge position, in which it is connected by one inlet end (46) and one outlet end (47) to a feed path (20) for the pumped air. At remote ends of the basic body (8) are provided pressure handles (5, 6) for the discharge actuation and a handle (7) for indexing or replacing a magazine body (16). Opening devices (50, 51) are used for the automatic opening of the magazine chamber (30) on transfer into the discharge position. This leads to a very reliable operation in the case of compact construction and easy handling.
