- 16 - ABSTRACT OF THE DISCLOSURE A rigid mount coupler in which all movement required for connecting and disconnecting the nipple occurs within the coupler housing. A body member which receives the valved nipple slides within the housing to actuate a locking mechanism to retain the nipple. The body member supports the coupler valve in a spring loaded retainer so that coupler and nipple valves engage and are balanced in valve open positions. A second spring loaded device supports the coupler valve at the open position and resists further opening movement, thereby preventing flow checking at the nipple. Seals between the body member and housing isolate a stepped chamber there- between in fluid communication with an inner chamber closed by the coupler valve. The volume of the stepped chamber changes upon movement of the body member and is dimensioned to corre- spond inversely to changes in volume of the inner chamber to prevent a fluid lock condition.
