Abstract:
Fluid discharge head having a discharge stub (5) which has a discharge opening (6) and in which an inner sleeve (7) is arranged which has a media channel (8) and which receives a spring-loaded valve body (10) self-acting closing the discharge opening (6) by a compression spring (20), the valve body (10) being formed as a cylindrical piston, which is axially displaceable in a cylinder chamber (12) formed by the inner sleeve (7), an upper valve seat (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) which is connected to the media channel (8) and in which, in order to open the upper valve seat (14), a media discharge pressure can be set and an opening characteristic is determined by a transmission ratio of the opening diameter of cylinder chamber (12) and media inlet in the area of the lower valve seat (15), characterized in that the transmission ratio is greater than 2 and the choice of the spring stiffness of the compression spring (20) establishes the media discharge pressure in the pressure chamber (19).
