HYDRAULIC COUPLER ABSTRACT OF THE DISCLOSURE An automatic coupling device having a body member movably mounted on a mounting plate fixed to the implement, and a sleeve member movably mounted on the body member. A releasable device between the mounting plate and the sleeve member releasably retains a coupler nipple on the sleeve member, the nipple including a first valve element urged toward a closed position and being movable to an open position. A valve body is slidably mounted in a bore of the sleeve member, the valve body having a passage with an inlet end for connection to a fluid line, and being movable to a first position to preclude substantially relative movement of the sleeve member and body member for locking of the nipple in the releasable device, and being movable to a second position to allow relative movement of the sleeve member and body member for insertion of the nipple into the releasable device. A cam is connected to the valve body for sliding the valve body in the bore of the sleeve member and for moving the valve body between the first and second positions. The valve body includes a second valve urged to a closed position and being movable to an open position, the first and second valves engaging and opening when the valve body is in the first position and the nipple is attached to form a fluid passageway through the valve body and nipple, and disengaging and closing when the valve body is moved to the second position, even when the nipple is attached.
