Abstract

Female and male parts 4, 5 comprise a rapid hydraulic coupling, one or each part being arranged with a pressure-eliminating function 10, 11 which comes into operation upon said coupling of the parts. When there is overpressure prevailing in the hydraulic system connected to one of the parts 4, 5 this overpressure is eliminated, so that coupling can be carried out counter to said overpressure in that hydraulic system. Each part 4, 5 has a valve member openable upon coupling, one valve being supported in a movable sleeve 17. A plurality of male parts can be coupled with corresponding female parts, together with electrical connectors, e.g. for a loader or vehicle with a lifting device.
