Abstract
A sealed hydraulic coupling comprises two coupling elements, each of which has an outer body, a rigid sleeve, and one part of a deformable duct which is fitted and gripped between the outer body and sleeve of the coupling element associated with it. The interior of each sleeve communicates with the interior of the associated duct part. An obturator is associated with each sleeve, which is closed by a closure member. Each sleeve is rigid and has a fluid flow port in its side wall, the end of each sleeve being closed by an end plug. The obturator of each coupling element comprises a sealing element interposed between the outer body and the corresponding end plug. One of these end plugs is fixed and carries a seating for a movable sealing ring, while the other one is movable and carries a further sealing ring. The invention is especially suitable for use with hydraulic clutch control systems for motor vehicles.
