Abstract
PURPOSE: To enable a proportional control operation for small rate of flow in a range of low electric current, by providing a fluid flowing passage of labyrinth constitution when in a closing state of the slide valve.
CONSTITUTION: A labyrinth 22 can be constituted by a ring-shape protruding piece 23, extended from the side wall of a bobbin 17 to axially external side, a groove 24, engaged to said piece, in the case inner wall, and a groove 26, engaged to an end part 25 extended from the bobbin side wall of a slide valve 9 fixed to the inner wall of the bobbin 17 in a relationship of floating with respect to a hollow core 10. In this way, if applied an electric current to an electromagnetic coil 16, though with the slide valve 9 actuated, the slide valve 9, being floating engaged to the hollow core 10, is not affected by a slide resistance from the above, consequently, an operation can be smoothly made in a range of low electric current, thus can be performed a proportional control of small rate of flow.
