Claim 10:
11. An arrangement for releasing a coupling connection of a hydraulic quick coupler, comprising:
a hydraulic coupling for receiving a hydraulic plug, the hydraulic coupling including a coupler housing and a coupler cartridge displaceably mounted therein such that when the hydraulic plug is pushed in, the coupler cartridge adopts an operating position locking the hydraulic coupling; and
a controller configured to instigate an external force for actuating the coupler cartridge;
wherein the coupler cartridge is movable from the operating position to an ejection position for releasing the hydraulic plug;
wherein for a build-up of pressure, a membrane accumulator is pretensioned by a pressure source and connected in a pressurized manner to a control chamber of via an activation valve which is triggered by the controller;
wherein first and second lines lead into the control chamber, the first line including a supply being connected in a pressurized manner to the membrane accumulator via a throttle valve and the activation valve, and the second line including a return being connected in a pressurized manner to a hydraulic reservoir via an outlet valve.
