Abstract
Apparatus for remotely controlling the internal pressure in a pneumatic tire, in which the inside of a pneumatic chamber mounted on a wheel is divided into a first chamber communicating with a fluid-supply source and a second chamber communicating with an air space in the tire by a diaphragm made of a flexible material. In an operation controlled from a vehicle cab, a fluid is introduced into the first chamber, thus compressing the second chamber so as to change the volume thereof, and thereby control the pressure in the air space with the tire by controlling the pressure in said second chamber.
Claims7
Apparatus for remotely controlling the internal pressure in an air space within a tire, said apparatus being mounted in a vehicle and comprising:
- a pneumatic chamber coaxially mounted on a wheel,
- a flexible fluid-tight diaphragm dividing said pneumatic chamber into two parts and preventing the transfer of fluid between said parts,
- means for connecting one of said chamber parts to the air space in said tire and means for connecting the other of said chamber parts to a source of fluid under pressure, said chamber parts being otherwise sealed, and
- means operable from a point near a control station from which said vehicle is controlled for remotely controlling the flow of fluid under pressure to and from said other chamber part to selectively increase and decrease the tire pressure.
