Title:
CONTROL METHOD FOR FLOW REGULATOR VALVE
Document Type and Number:
Japanese Patent JPS5989869
Kind Code:
A
Abstract:
PURPOSE:To reduce the drive force required to switch the rate of flow to high- speed position, by quickly lowering the axial thrust force of a valve spool, given by a fluid to be controlled, in accordance with increase in the amount of opening of the valve spool. CONSTITUTION:An incoming port 12 and an outgoing passage 13 for the fluid are formed in a cylinder chamber 11, and a valve spool 14 partitions the chamber into a compartment 11A on the incoming side and another 11B on the other side. A communication hole 15 is formed in this valve spool 14. A drive rod 16 is coupled with a driver device to be moved in the axial direction at a high speed. Adjustment of the rate of flow of the fluid to be controlled is made by adjusting the degree of opening of said valve spool 14, i.e. the amount of opening of the outgoing passage 13.
