Abstract:
A hydraulic coupling arrangement, comprising:a) an outer, tubular body extending along a longitudinal axis and having a flow channel through which a pressurized fluid flows, and a discharge passage for discharging the fluid during coupling; b) a tubular bushing mounted at an axial end region of the body; c) an inner, tubular, first movable member mounted on the bushing for axial movement when subjected to an axially-directed force during coupling; d) a coupler mounted at an axial end region of the first movable member; e) an inner, tubular, second movable member connected to the first movable member for joint movement therewith; f) a bypass passage extending between the flow channel and the discharge passage through the first and second movable members; and g) a radially offset valve mounted in the second movable member within the bypass passage for movement along an offset axis parallel to the longitudinal axis between a closed position in which the valve blocks the flow of the fluid to the discharge passage, and an open position in which the valve enables the fluid to flow to the discharge passage during coupling.
