Title:
EXHAUST GAS RECOVERING-DEVISE FOR AIR CYLINDER
Document Type and Number:
Japanese Patent JP3705730
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an exhaust gas recovering-device for an air cylinder that can reduce air consumption by returning the exhaust gas of the cylinder to an air power supply and thus drive the cylinder at low cost.
SOLUTION: This recovering-device is equipped with a three-port valve 20 and a booster valve 30. The three-port valve 20 releases lower pressure exhaust air to atmosphere and outputs higher one than a given pressure, from among exhaust air from the air cylinder 11. The booster valve 30 boosts the exhaust air outputted by the three-port valve 20, and then outputs the boosted air to an air power supply P for the cylinder 11.
