ABSTRACT:
A solenoid actuated valve device for electrically controlling the flow of fluid in response to electric signals. The valve device comprises a body member defining an internal chamber, a core being made of a magnetic material and comprising a central hollow portion, a bobbin slidably mounted on the core, a solenoid coil wound on the bobbin, a permanent magnet the magnetic flux of which may intersect at right angles to the winding of the solenoid coil, a yoke being made of a magnetic material and forming a magnetic circuit of the core, passages formed on the core, a sliding valve controlling the open area of the passages in response to the movement of the bobbin, and a spring biasing the bobbin so that the sliding valve may close the passages, whereby the flow of fluid may be controlled in proportion to the electric current.
