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 12):
A two position, three-way solenoid-operated fluid control valve comprising:\n a valve body having three ports respectively for connection to a supply of pressurised fluid, a tank or reservoir and a fluid circuit, the valve body comprising a central bore; a valve element received in said central bore and comprising first and second segments, wherein each segment comprises\n a pair of seals at each end of the external surface of the valve element such that the segment is sealed to the internal bore surface of the valve body, \n an annular groove axially between the seals for communication with one of said ports, \n an axial central bore, \n an inwardly facing end having an annular recess and a concave valve seat defined around the central bore radially inboard of the annular recesses; \n a first actuating pin slidably positioned within the axial centre bore of the first segment and a second actuating pin slidably positioned within the axial centre bore of the second segment; an annular spacer disposed between the segments and received in the annular recesses of the inwardly facing ends for axially spacing the segments; a spherical valve member positioned between the concave valve seats of the first and second segments; and wherein the valve further comprises a solenoid and a first spring at a first end of the valve body and arranged to bias the first actuating pin in a first axial direction; and a second spring at a second end of the valve body and arranged to bias the second actuating pin in an opposing axial direction.
