Method of adjusting the pressure of the tires on a vehicle
First Claim
1. A method of adjusting the pressure of the tires on a vehicle equipped with a centralized inflating installation which includes a compressed-air source, a selector and lines, a rotary seal and an isolating valve between the selector and each tire, said method including, successively for each tire, the following steps controlled by the selector:
- connecting the compressed-air source to the tire via the line and rotary seal associated with the respective tire, this having the effect of opening the isolating valve, after a very short time closing the compressed-air inlet to the line, then measuring the pressure in the line which has become the same as the pressure in the tire, and then venting said line to atmosphere, this having the effect of closing the isolating valve, characterized in that the duration of said very short time is determined as a function of the set pressure to be obtained in the tire in question, and in that the operation is repeated at least until said set pressure has been obtained.

Abstract
Method of adjusting the pressure of the tires on a vehicle equipped with aentralized inflating installation which successively connects up each tire to the compressed-air source via a line, a rotary seal and a differential-type isolating valve, then closes the compressed-air inlet after a very short time, and repeats these operations iteratively. According to the invention, a value of the set pressure corresponds to a value of the duration of the very short time.
