Patent ID: 7311337

Claim:
A housing structure and hydraulic coupling arrangement, the housing structure having at least two housing sections, each of which is provided for covering the hydraulic coupling arrangement, each housing section being substantially cylindrical, the hydraulic coupling arrangement having a first hydraulic coupling disposed above a second hydraulic coupling and a housing section having an opening that is reversibly sealable with a closing element and through which a counterpart of a hydraulic coupling can be inserted to create a hydraulic connection, the housing structure further having an area for collecting leaking fluid, and a retaining and conveying structure formed in the shape of a ring and having an inwardly directed projection being arranged along an entire perimeter of an interior of the substantially cylindrical housing section near the hydraulic coupling by which the leaking fluid escaping from the upper hydraulic coupling and located in the housing section allocated to said hydraulic coupling can be taken to the area for collecting leaking fluid.
