ABSTRACT:
A first member of a magnetic housing has a core with a central passage and contains an electrical coil, and a second member of the housing has a ball cavity which receives and guides a magnetic ball. A central conduit and peripheral conduits enter the cavity of the second member. When the coil is activated, the magnetic field created thereby moves the ball into contact with the core to close the central passage in the first member, leaving the central and peripheral conduits in communication with each other. When the coil is deactivated, fluid pressure moves the ball to a position where it closes the central conduit so the central passage and the peripheral conduits will be in communication.
