<p>A coupling member 1 includes a valve body (3a, 3b, 3c) which is fixed, and a longitudingally-displaceable sleeve (4) which in a sealing position is designed to seal against the valve body, via a sealing element (7) arranged on the latter. The sealing element (7) is arranged in the valve body in such a way that in the sealing position the sleeve extends past the sealing element. The pressure medium within the valve body acts on the sealing element and thus contributes towards effective mutual sealing between the valve body and the sleeve (4). On insertion of a male coupling member 2 into the coupling member 1 the sleeve 4 is pushed back by engagement between a surface 2a in the member 2 and a shoulder 4c on the sleeve 4. <IMAGE></p> |
