Abstract
Apparatus for controlling and maintaining air pressure in vehicle tires. The vehicle compressor outlet is connected through individual pneumatic tire circuits to each vehicle tire, via rotary couplings in the associated axles. Each tire circuit includes tubing for carrying air and monitoring tire pressure, the circuits supporting pressure sensors and electrovalves housed in a control unit in the dashboard of the vehicle. The control unit also houses electronic circuits interfaced with the sensors and electrovalves. The sensor includes a piston which causes a shutter to move in and out of the light path of a LED/phototransistor device. When it signals low tire pressure to the electronic circuit, the corresponding electrovalve is energized for the compressor to pump the tire up back to its set pressure. A front panel has LEDs and gauges for the driver to keep tabs on events.
