AUTOMATIC SYSTEM FOR AIR PRESSURE REGULATION IN TIRE Russian patent published in 2012 - IPC B60C23/02 

FIELD: transport.

SUBSTANCE: invention relates to transport machine building, in particular it can be used in running rear of vehicles. The system contains stub axle, inner sealing on stub axle, air receiver, pipeline connecting pneumatic tire with inner sealing on stub axle where inner sealing on stub axle is connected with air receiver via stud-bolt and main line into which solenoid valve connected with control unit is built. Additionally piston pump-damper is introduced which is provided with upper and lower relief valves made in housing and relief valves made in piston which divides interior space into two chambers. Via upper relief valve and additional inflation line, piston pump-damper communicates with air receiver, and via lower relief valve, additional deflation line, additional air receiver with safety valve, and piston pump-damper communicates with the main line. Control unit receives signals from pressure sensor located in the main line and from bouncing sensor located on piston pump-damper housing.

EFFECT: higher travelling comfort of vehicle.
