Abstract:
A directional control valve has a first fluid path extending between first and second ports and a second fluid path between second and third ports. A spherical valve member moves between an open position in which the valve member is displaced from a first valve seat so that the first fluid path is open and is sealed against a second valve seat so that the second fluid path is closed and a closed position in which the valve member is sealed against the first valve seat so that the first fluid path is closed and displaced from the second valve seat so that the second fluid path is open. The valve member is biased towards the closed position by opposed first and second biasing members of unequal loading. An actuator can move the valve member from the closed position to the open position against the unequal loading.

Claim (Index 1):
A directional control valve comprising:\n a housing defining first, second and third ports and having a central bore in communication with said ports; a first fluid path between the first and second ports and a second fluid path between the second and third ports; first and second spaced apart valve elements sealed to the internal surface of the central bore of the housing, the valve elements defining a chamber at an intersection of the first and second fluid paths, wherein the valve elements comprise opposed spaced apart valve seats, and each valve element having an axial central bore coaxial with the valve seats and extending from a distal end of the valve element to the valve seat; first and second actuating pins slidably each positioned within the axial central bore of one of the first and second valve elements; a substantially spherical valve member disposed between opposed, spaced valve seats in the chamber; an annular spacer positioned between the valve elements to define the axial spacing between the valve elements and comprising a peripheral recess to allow fluid to flow around its outer surface and a plurality of radial ports for fluid flow radially to/from the region around the spherical valve member; the valve member being movable across the chamber, by the first and second actuating pins, between the valve seats between an open position in which the valve member is displaced from a first valve seat so that the first fluid path is open and is sealed against a second valve seat so that the second fluid path is closed and a closed position in which the valve member is sealed against the first valve seat so that the first fluid path is closed and displaced from the second valve seat so that the second fluid path is open; the valve member being biased towards the closed position by opposed first and second biasing members of unequal loading; and an actuator for moving the valve member from the closed position to the open position.
