ABSTRACT:
An improved hydraulic coupler assembly of the type having a base plate which carries fixed and movable blocks. A spring biases the blocks away from one another with one end of the movable block received inside a bore of the fixed block. First and second nipple members are received inside the movable block with one of the nipple members being slidable therein. The other nipple member is releasably locked in the movable block by a plurality of locking balls engaged by a locking rib on the fixed block. A pivot lever member operates on both the slidably mounted nipple member and the movable block to first move the nipple members apart to stop the hydraulic flow therethrough and to then move the movable block towards the fixed block against the force of the spring to unlock the locking balls, whereby the removable nipple member may be easily uncoupled from the movable block. The lever member comprises a cam operative in a slot in the base plate and a pivot plate operable in a groove in the slidable nipple member. The lower end of the pivot plate is received in an angular slot in a support plate carried on the pivot lever member.
