Title:
PRESSURE HOLDING DEVICE PRESSURIZED BY AIR PRESSURE BOOSTER
Document Type and Number:
Japanese Patent JPS58152901
Kind Code:
A
Abstract:
PURPOSE:To pressurize fluid pressure to required pressure in a short time, by equipping a selector device selecting high pressure air, in which pressure air supplied to a booster is pressurized to required pressure, to low pressure air which holds said required pressure after pressurized to the required pressure. CONSTITUTION:If air of pressure p3 is supplied to an air pressure booster 4 by a position (a) of a direction selector valve 12, pressurized fluid is delivered from the booster 4 to increase internal pressure in a pressure fluid chamber 6. When the internal pressure in the chamber 6 reaches required pressure p2, the valve 12 is selected from the position (a) to (b) to stop supply of the air of pressure p3 to the booster 4. Then a direction selector valve 13 continues to hold a condition of (a) and supplies air of pressure p2 met to required fluid pressure, and the chamber 6 holds fluid to the pressure p2 to enter the holding action of pressure.
