摘要 |
<p>In a fluid control valve, a valve spool doubling as a plunger of a solenoid is slidably installed on a shaft member, i.e., the valve spool and the shaft member are joined by providing therebetween an annular clearance. The shaft member is formed with three or more pressure chambers and radial restriction holes in constant communication with the pressure chambers. The pressure chambers and the radial restriction holes are arranged at equal circumferential intervals and in constant communication with an outside pressure source so that the annular clearance is maintained uniform, i.e., the valve spool is self-centered relative to the shaft member by the effect of the fluid pressure supplied to the pressure chambers at all times.</p> |
