Abstract:
1. A fluid coupling comprising a female half and a male half, said female half having a longitudinal bore extending completely therethrough for the passage of fluid through said female half, said female half having an inner surface at said longitudinal bore, sealing structure at said inner surface of said female half, locking structure at said inner surface of said female half, said male half having a longitudinal bore extending completely therethrough in flow communication with said longitudinal bore of said female half when said female half and said male half are coupled together, said male half having a nipple on its lead end for insertion into said longitudinal bore of said female half, complementary sealing structure on said nipple for engagement with said sealing structure of said female half when said female half and said male half are coupled together to create a fluid tight seal between said female half and said male half, complementary locking structure on said nipple for interaction with said locking structure of said female half to maintain said female half and said male half coupled together, an anti-rotational sleeve slidably mounted on one of said female half and said male half, the other of said female half and said male half having a non-circular outer surface, said sleeve having an inner surface portion of a shape which acts as a stop structure to abut against said non-circular outer surface and prevent relative rotation of said female half and said male half when said sleeve is slid to a position where said sleeve inner surface portion is around said non-circular outer surface, and said sleeve being slidable to a position where said non-circular outer surface is free of said sleeve inner surface portion to thereby permit relative rotation.
