Latest Patents

Hakan Johansson holds a patent for a fluid pressure relief valve with variable opening pressure. This invention includes an aperture through which fluid can flow. An element is movable to unseal the aperture and to open the valve when a force exerted by the fluid in the valve exceeds a predetermined force. An electromagnetic biasing arrangement biases the element to seal the aperture and hold the valve closed against the escape of fluid with the predetermined force. The applied bias is variable according to changes in the sensed position of the element. A monitoring arrangement, cooperable with the solenoid, monitors the changes in its electrical properties as a shaft moves in the monitoring arrangement, indicating a change in position of the element. The monitoring arrangement also varies the bias to reduce the predetermined force responsive to the sensed change in position of the element, indicating an opening of the valve.
