A quick coupler includes a housing in which a first and a second coupler cartridge are received. The spaced-apart center axes of the first and second coupler cartridges each run parallel to a vertical axis such that the center axes are contained in a common reference plane. The quick coupler further includes a first actuating lever and a second actuating lever for actuating the coupler cartridges. First and a second axes of rotation of the respective first and second actuating levers are oriented perpendicularly to the reference plane, and a first actuating arm and a second actuating arm are arranged to perpendicularly to the reference plane on opposite sides of the housing.

A hydraulic coupling bush which is actuated in order to close or open the coupling includes a coupling housing and a bush body which displaceable therein and which has a plug space for receiving a coupling plug, a supply space for fluidic connection to an external supply channel, a low pressure space for fluidic connection to a pressure medium sink, and an interior space connected fluidically to the supply space, a supply seat valve device being provided, via the actuation of which a supply flow path can be configured between the supply space and the plug space, and a relief seat valve device being provided, via the mechanical actuation of which the interior space can be relieved of pressure toward the low pressure space, and via the hydraulic actuation of which, which is dependent on the pressure in the interior space, the pressure in the interior space can be limited.
