Patent ID: 8747134

Claim:
Plug-in coupling for the transfer of high-power energy and for the transfer of a fluid under pressure, comprising: at least one coupler plug ( 2 ) and at least one coupler socket ( 3 ), in which the coupler plug ( 2 ) can be introduced into the coupler socket ( 3 ) at least to some extent to produce a coupled state and can be removed from the coupler socket ( 3 ) to produce a decoupled state, characterized in that the coupler socket ( 3 ) and the coupler plug ( 2 ) respectively comprise an inner conductor ( 4 , 5 ) which is electroconductive in at least some sections and which is surrounded by a fluid channel ( 6 ) in at least some sections and that the coupler socket ( 3 ) and the coupler plug ( 2 ) have means ( 7 , 8 ) for sealing the fluid channel ( 6 ) in a liquid-tight manner in the decoupled state and for producing a continuous fluid channel ( 6 ) in the coupled state, characterized in that the means are spring-loaded, movable valve bodies ( 7 , 8 ), characterized in that the valve bodies ( 7 , 8 ) in the coupled state are moved so that the plug-in coupling ( 1 ) forms a continuous fluid channel ( 6 ), characterized in that at least one of the valve bodies ( 7 , 8 ) is designed to produce an electroconductive connection between the inner conductors ( 4 , 5 ) of the coupler socket ( 3 ) and of the coupler plug ( 2 ), wherein the valve body ( 7 ) of the coupler plug ( 2 ) consists at least to some extent of the inner conductor ( 4 ), wherein the coupler socket ( 3 ) comprises a coupler socket housing ( 3 . 2 ), the valve body ( 8 ) being movable between the inner conductor ( 5 ) and the coupler socket housing ( 3 . 2 ).
