Patent number: 10260646Abstract: 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.Type: GrantFiled: January 18, 2018Date of Patent: April 16, 2019Assignee: Bifold Fluidpower LimitedInventors: Michael T.
