Tire inflation/deflation system
First Claim
1. An automatic tire inflation-pressure regulating system for wheeled vehicles with pneumatic tires comprising:
- means fitted on each of the road wheels of said vehicle for regulating the inflation pressure of said pneumatic tires mounted on said wheels, said pressure regulating means including deflation means and inflation means in fluid communication with the interior of said tires, and RF signal receiving means associated with means for actuating selectively either said deflation means or said inflation means;
RF signal transmitting means on said vehicle at a location proximate each of said wheels for providing command signals to said signal receiving means for activating said tire inflation-pressure regulating means on said wheels;
control means in said vehicle operable manually by an occupant thereof and connected to said RF signal transmitting means for providing command inputs for selectively deflating or inflating said tires.

Abstract
An automatic tire inflation-pressure regulating system for wheeled vehicles with pneumatic tires. The system has a system control assembly in the vehicle operator'"'"'s compartment, control signal transmitter assemblies on the vehicle body in close proximity with each vehicle road wheel, and a tire pressure-regulating wheel assembly on each wheel. The transmitter assemblies convert electrical command signals initiated by the control assembly to RF signals that are received by an electronic module in each wheel assembly. Means in each wheel assembly selectively deflate or inflate their respective tires in response to the RF control signals. Gas under pressure for inflating the tires is provided either by a plurality of gas generators or by a pressurized gas-generating liquid.
