High-pressure coupling device for directing media through quick-change systems

High-pressure coupling for the Media duct to quick-change systems, such as oil, water, gases, oils and fats and the like, with the high-pressure coupling of a coupling part and a clutch shell composed,characterized, thatthe lower coupling part a firmly anchored, rigid valve mandrel comprising in the form of a valve screw which together with a spring-loaded slide valve sleeve the Sealing effect for the supply of the high-pressure medium causes, and the upper coupling part having a spring-loaded valve disc which together with a rigid valve body the sealing action for which causes high pressure medium to be supplied side of the clutch, so that when merging the coupling part with the coupling shell in the sense of valve actuation each a rigid valve element, the spring-loaded valve member the counterpart operated in the high-pressure coupling.
