Abstract
A quick connect fluid coupling is disclosed for use with a tubular and cylindrical nipple having an annular recess at a position spaced from its free end. The quick connect coupling includes a tubular and cylindrical body open at each end and wherein the first end of the body is coaxially disposed over the nipple. The body includes a plurality of circumferentially spaced and radially extending openings which register with the recess and the nipple once the body is moved to its connected position. A spherical retainer is positioned within each radial opening and these retainers are radially movable between an inner locked position in which a portion of each retainer is positioned within the recess, and an outer unlocked position in which the retainers are spaced outwardly from the recess. A locking collar is disposed coaxially around the body and is axially movable between an extended and a retracted position. In its extended position, a cam surface in the collar coacts with the retainers to move the retainers from their outer and to their inner locked position. An annular ring is also disposed within the first end of the body so that the ring is in alignment with the retainers. The…
