In a discharge device including two mutually shiftable units (2, 3) permanent magnets (14, 24, 33, 34) are provided for controlling a piston unit (20) and valves (13, 23, 45), the magnetic force of these magnets being provided more particularly to cause a reset movement into the starting position. These magnets may be immersed in the medium or surrounded on all sides by the medium flow, thus enabling mechanical springs to be eliminated and assuring highly reliable functioning.
