Abstract: A dispenser for flowable media is provided, which operates in user-independent manner with respect to the pressure buildup and dosage quantity. On pressing on an operating head (35) a piston rod (29) is forced into a pump cylinder. As the pump chamber (52) is sealed by means of a delivery valve (51), which operates in path-dependent manner as a slide valve, under the action of a spring (42) pressing on the piston collar (43), a pressure builds up in the pump chamber (52), which is released following a predetermined length of travel on opening the delivery valve. A relatively constant pressure can be obtained over the entire discharge phase through the pretension of spring (42).
