<p>Coupling arrangement comprising connectable male and female parts (1, 2). The male part can be partially inserted into the female part. The female part comprises a longitudinally displaceable inner sleeve (4) which, in the non-actuated position of the female part, is caused to assume a closed position. When the male part is inserted into the female part, the inner sleeve is acted upon counter to the action of a spring function towards an open position, in which the media passage through the coupling is open. At its section (18) which can be inserted into the female part, the male part is provided with an inner surface (18a) which, upon insertion of the male part into the female part, surrounds a corresponding outer surface (4d) on the inner sleeve. Sealing members (18b, 18c and 21) prevent media leakage during the coupling movement of the male and female parts. The inner sleeve is designed so as to execute, upon exposure to a media pressure, for example a media pressure in the male part, a longitudinal displacement movement towards its fully open position dependent on the media pressure and independently of the male part. The said sealing members effect their sealing function during the whole of the independent longitudinal displacement movement.</p> |
