ABSTRACT:
A housing structure is provided having at least two housing sections each provided for covering and/or closing a hydraulic coupling, particularly for dust protection. A first hydraulic coupling is disposed above a second hydraulic coupling, preferably in a vehicle or tool, such as a commercial agricultural or industrial vehicle. A housing section has 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 has an area disposed below for collecting leaking fluid. Retaining means are provided for each reversibly sealable opening by which the escape of leaking fluid from the respective opening is largely preventable. Wetting of the hydraulic coupling with leaking fluid and the escape of leaking fluid from the opening of the housing structure is avoided by simple structural means. The housing structure has conveying means by which the leaking fluid escaping from the upper hydraulic coupling can be conveyed at least for the most part to an area for collecting leaking fluid.
