WIPO Patent Application WO/2012/093745
Kind Code:

Abstract:
The present invention relates to a pneumatic circuit system of an air spring for a vehicle and a method for controlling the pneumatic circuit. The pneumatic circuit system includes: a compressor (3) for suctioning and compressing external air; a dryer (5) for removing moisture from the air compressed by the compressor (3); a one-way valve (7) allowing the air transferred from and dried by the dryer (5) to pass therethrough, thereby introducing the air into the air spring (10), the one-way valve (7) preventing the air introduced into the air spring (10) from passing therethrough, thereby exhausting the air introduced into the air spring (10) toward the dryer (5); a switching valve (9) that is closed when the air is introduced into the air spring (10) so that the air is introduced through a pipe (c), the switching valve (9) being opened when the air is discharged from the air spring (10) so that the air is discharged through the pipe (c); a throttle valve (11) throttling the air discharged from the air spring (10) to remove moisture within the dryer (5); and an exhaust valve (13) opened to discharge the air passing through the throttle valve (11) to the atmosphere. Thus, since the one-way valve is disposed on the pipe in which the air is filled from the compressor to the air spring, the air supplied from the compressor may be directly filled into the air spring without passing through the switching valve. Accordingly, the pipe for filling the air into the air spring may be further simplified in structure.
