AIR SELECTOR VALVE FOR VIBRATION CONTROL DEVICE AND VIBRATION CONTROL DEVICE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a new structure air selector valve for a vibration control device capable of controlling air pressure change accurately and steadily at a frequency and a phase corresponding to vibration to be controlled while controlling a temperature rise caused by heat generation during the energization of a coil. SOLUTION: A central cooling passage 18 passing through a core part of a solenoid coil 26 provided in the air selector valve 10 for a vibration control device in an axial direction is provided. An outer circumference cooling passage 48 is provided on an outer circumference surface of the solenoid coil 26 and cooling air is forcedly sent to the outer circumference cooling passage 48.
