Zusammenfassung:	Fluid discharge head having a discharge nozzle (5) which has a discharge opening (6) in which an inner sleeve (7) is arranged, which has a medium duct (8) and holds a spring-loaded valve body (10) automatically closing the discharge opening (6), the valve body (10) being formed as a cylindrical piston, which can be displaced axially in a cylinder chamber (12) formed by the inner sleeve (7), an upper (14) and a lower valve seat (15) being provided for the piston ends (16, 17), and the valve body (10) having an intermediate valve plate (18), which forms a chamber bottom of a pressure chamber (19) connected to the medium duct (8), and, in order to open the upper valve seat (14), a medium discharge pressure which is higher than a spring force holding the valve body (10) closed can be set in the pressure chamber.
