AIR PURGER
Document Type and Number:
Japanese Patent JPS5861312
Kind Code:
A
Abstract:
PURPOSE:To reduce the number of times of operation of a master cylinder for air purging, by installing a check valve in a liquid pipe for conducting air-mixed liquid out of a working cylinder to a drain tank. CONSTITUTION:When an air vent valve 12 is opened and a master cylinder is operated, liquid discharged from the master cylinder mixes with air and flows into a hydraulic chamber 5 and is conducted to a valve chamber 27 through a hole 13, the passage hole 14 of the valve 12 and a liquid pipe 17 so that the liquid pushes and opens the slit part 26 of a valve member 23 and goes out into a drain tank 18. When the master cylinder is put out of operation, the liquid in a reservoir is supplied into a hydraulic pressure generating chamber. At that time, the air does not flow back into the hydraulic chamber 5 because the slit part 26 of a check valve 20 is closed.
