<p>A rotary valve type quick coupling for interconnecting two pressure medium conduits and comprises on one hand a coupling unit (10) including a casing (14) and a spherical rotary valve element (18) formed with a socket (27), and on the other hand a tubular connector nipple (12) adapted to be guidingly received in the socket (27), and an elongate aperture (32) in the casing (14) which permits the connector nipple (12) to be introduced into the valve element socket (27) and to be rotated conjointly with the valve element (18) between a connect/disconnect position and a connected position. A transverse annular shoulder (46) on the nipple (12) is arranged to engage a guide surface (45) on the casing (14) to guide the nipple (12) and the valve element (18) as they occupy the connect/disconnect position.</p> |
