Abstract

The problem of the invention is to so further develop a discharge apparatus according to the preamble that it is possible during each individual actuating stroke to reliably discharge a predetermined volume of medium.A discharge apparatus for media according to the invention has a casing, on which is located an actuator. During each actuator actuation an actuating stroke takes place and consequently a given volume of the medium stored in the casing is discharged. According to the invention the gravity dependently operating blocking means are constructed in such a way that they can block the performance of an actuating stroke as a function of the spatial position of the discharge apparatus.
