Abstract
Abstract A coupling apparatus having a male member and a female member. The male member includes a flow passage having radially extending ports and a valve means. The female member includes a body member having an interior surface and a flow passage, a socket member having an exterior surface and a flow passage, and, an insert member having a first complementary surface and a second complementary surface. The valve means of said male member allows communication between said radially extending ports and said flow passage of said socket member. The interior surface of said body member is engaged in sliding contact with said first complementary surface of said insert member thus permitting universal movement of said insert member relative to said body member. The exterior surface of said socket member is engaged in sliding contact with the second complementary surface of said insert member thus permitting radial movement of said socket member relative to said insert member. The radial movement of said socket member and the universal movement of said socket member, in combination, absorb angular and radial misalignment of said male member and said female member during engagement.
