CA 2273593
A coupling comprising a male portion and a female portion wherein the female portion comprises: a housing, an inner body member positioned within the housing and slidable relative thereto, a relief valve positioning member, a piston residing intermediate the relief valve positioning member and the inner body member and slidable relative to the positioning member and the inner body member, and a valve. The housing includes a first port and a second port. The inner body member includes a port communicating with the first port of the housing. The relief valve positioning member includes a relief valve. The piston includes an interior, an exterior, and a passageway interconnecting the interior of the piston and the exterior of the piston. The valve slidably engages the piston and seats against the inner body member. The male portion of the coupling engages the inner body of the female portion. A chamber is formed between the piston and the relief valve positioning member which, when pressurized, results in the movement of the positioning member when the inner member is moved leftwardly during coupling with the male portion. Movement of the inner body of the female portion moves the relief valve positioning member axially away from the male member opening the relief valve and venting the female member through the second port of the housing of the female member.
