Abstract
A device and method for dispensing a flowable medium has a housing with an interior space and a rod mounted in the housing that is movable between a first end position and a second end position and passes through a diaphragm mounted in a sealed manner in the housing radially on the outside and in the rod radially on the inside. The diaphragm divides the interior space into a first cavity and a second cavity separated from the first cavity in a fluid tight manner. The flowable medium can flow through at least one channel that opens into the first cavity, and is dispensed through a dispensing opening. A sealing section of the rod closes the dispensing opening in the first end position and is at a distance from the dispensing opening in the second end position. A pressure medium acts on the diaphragm in the second cavity.
