Title:
FLUID CIRCUIT FOR AIR CYLINDERS
Document Type and Number:
WIPO Patent Application WO/2019/049434
Kind Code:
A1
Abstract:
A fluid circuit (10) for air cylinders is provided with a switching valve (14), an air supply source (16), an exhaust port (18), and a check valve (20). When the switching valve is in a first position, one cylinder chamber (32) is connected with the air supply source, and the other cylinder chamber (34) is connected with the exhaust port. When the switching valve is in a second position, the one cylinder chamber is connected with the other cylinder chamber via the check valve, and the one cylinder chamber is connected with the exhaust port. The acoustic velocity conductance of a pipe (40) connecting the switching valve and a cylinder port part (36) of the one cylinder chamber is lower than the acoustic velocity conductance of the switching valve and the cylinder port part of the one cylinder chamber.
