Abstract
PURPOSE: To make a valve smoothly follow the output current of a controller and stabilize control, by supporting a plunger which drives the valve with elastic bodies and preventing the plunger from touching an electromagnetic coil.
CONSTITUTION: An electromagnetic coil 20 is set in a supporting member 19 of a servo valve body 14 concentrically with a servo valve 18. A plunger 21, going up and down by the excitation of the electromagntic coil 20 and controlling an opening between the servo valve 18 and a servo valve seat 17, is fit in the hollow portion of the electromagnetic coil 20 freely to go up and down, being supported by elastic bodies 22 fixed respectively on both upper and lower end surfaces of the supporting member 19, and a gap is always kept between the plunger 21 and the electromagnetic coil 20. Accordingly, the plunger 21 moves exactly and smoothly in its axial direction.
