Abstract
A rotary valve type quick coupling for interconnecting two pressure medium conduits comprises a coupling unit (10) including a casing (14) and a spherical rotary valve element (18) formed with a socket (27), and a tubular connector nipple (12) adapted to be guidingly received in the socket (27). An elongate aperture (32) is provided 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.
