ABSTRACT:
To enable a tool with a hydraulic actuator to be connected directly and quickly to a four-way, three-position control valve, the bodies of the tool and the valve are formed with sockets which receive fittings for establishing fluid communication between the tool and the valve. The fittings are anchored in the sockets of one of the bodies and are adapted to be telescoped slidably into the sockets in the other body to enable the bodies to be quickly and easily connected to and disconnected from one another. The arrangement is such that the same four-way, three-position control valve may be connected either to a tool having a double-acting hydraulic actuator or to a tool having a single-acting hydraulic actuator.
