Title:
FLUID PRESSURE AMPLIFIER SYSTEM
Document Type and Number:
Japanese Patent JPS5642701
Kind Code:
A
Abstract:
PURPOSE:To give big outputs to an output shaft by forcing liquid pressure which has amplified outputs by a pressure amplifier into a liquid pressure chamber separated by pistons equipped with an output shaft. CONSTITUTION:When pressured gas is let from a pressured gas source 27 into an air pressure chamber 21 of a pressure amplifier 20, the gas pressure is amplified and transferred through pistons 23, 17 into a liquid pressure chamber 19, eventually it can thrust down a piston 5, consequently an output shaft 3 by a big force. And in case where the output shaft 3 is returned to the initial position, at the same time as air pressure in the air pressure chamber 21 is released, pressured gas is sent to the air pressure chamber side 12 of a pressure transducer 10 by action of a directional control valve 25, which is transduced into liquid pressure to thrust up the piston 5.
