Coupling arrangement for a hydraulic deive, and method for coupling and fluidically connecting first and second coupling component of the coupling arrangement

A coupling arrangement for a hydraulic device, the coupling arrangement comprising:

• a first coupling component and a second coupling component, the first coupling component and the second coupling component being transferable from an uncoupled state into a coupled state;
• the first coupling component has a hydraulic chamber that is prefilled with a first hydraulic liquid, and the second coupling component has a hydraulic cylinder that is prefilled with a second hydraulic liquid;
• the hydraulic chamber and the hydraulic cylinder are fluidically connected to one another in the coupled state of the first coupling component and the second coupling component;
• a first flow opening is incorporated in the hydraulic chamber, and the first coupling component has a first sealing device;
• and
• the first sealing device is configured to close the first flow opening in a flow-tight manner in the uncoupled state and frees the first flow opening in the coupled state for fluidic connection of the first coupling component to the second coupling component.
