ABSTRACT:
The present invention provides a new and improved solenoid actuated valve device for controlling the flow of fluid comprising a body having an inlet and an outlet port extending therethrough, a hollow tubular core axially mounted within said body with one end thereof disposed in communication with said outlet port and having at least one radially extending aperture therethrough to provide communication between said inlet port and said outlet port, a bobbin slidably mounted on said core to control the effective open area of said aperture, a solenoid coil wound on said bobbin, an annular yoke resiliently mounted within said body, permanent magnets secured in said yoke so that the magnetic flux thereof intersects the windings of said solenoid coil at right angles thereto, a cover secured to said body in engagement with the other end of said core, said body, said cover member, said yoke and said core being of magnetic material to define a magnetic circuit with said permanent magnets to provide a magnetic force causing said bobbin to move relative to said core when an electric current passes through said coil, springs biasing said bobbin to a position closing said aperture and resilient stoppers against which said bobbin will bear in the closed position relative to said aperture. The resilient stoppers also act to resiliently support one end of the yoke in sealing engagement with the body intermediate said inlet and said outlet ports.
