Remote control of pneumatic tire pressure and its apparatus

摘要

Apparatus for remotely controlling the pressure in a pneumatic tire in which a pneumatic chamber communicating with a tube inserted in a tire and a chamber whose internal pressure is remote-controlled from the cab are aligned on the same axle of a vehicle. The piston penetrates into both chambers and the internal pressure in the tube can be adjusted by changing the internal volume of the pneumatic chamber due to displacement of the piston.
