摘要： In a fluid coupling a bellows holder (21) and a shower ring (25) are axially movably mounted in a housing (15, 16, 17, and 18); the holder (21) supports a bellows (22); the shower ring (25) is fixedly mounted in the holder (21); the bellows (22) has a valve (39) in its front end; the valve (39) is disposed in the shower ring (25); the shower ring (25) has a cleaning chamber (25a) which is round in cross section to receive therein a plug (6) being coupled; the plug (6) has a valve (31) corresponding to that of valve (39) of the bellows holder (22); an O-ring 47 is disposed in an intermediate portion of the chamber (25a) which has an injection spout (46) in its side wall; a nozzle (43) is disposed in wall portion of the housing (15, 16, 17, and 18) and the housing (15, 16, 17, and 18) having a drain (50) disposed therein; the nozzle (43) supplies wash water to a spout (46) in shower ring (25); whereby, a strong current of wash water is introduced into the cleaning chamber (25a) and about an outer peripheral surface of the plug (6) entirely washing the cleaning chamber (25a) and such peripheral surface, thereby, substantially reducing fluid stagnation.
