System for regulating tire inflation pressure
First Claim
1. A system for regulating pressure in a tire comprising an outer casting mounted on a wheel rim, wherein the tire comprises an inner casting disposed at an end of the wheel rim, a first actuator integrated into the inner casting allowing a passage of air to the outer casting to inflate the outer casing, a second actuator integrated into the outer casting allowing the air to be evacuated to deflate the outer casting, an electronic assembly able to emit data at least to one of the actuators and/or to receive data given by at least one detector in order to control a pressure and a temperature in the outer casting and/or the inner casting, and a controller for the electronic assembly and a keyboard, the system controlling a value of the pressure in the outer casting between a minimal and a maximal value according to a control logic in relation with external conditions to which the tire is subjected and ensuring a constant control of the value of the pressure in the tire.

Abstract
The invention relates to a system for regulating the pressure in a tire comprising an outer casting (3) which is mounted on a rim (2).
The tire comprises an inner casting (5) which is disposed at the bottom of the rim (2) and which can constitute a high-pressure air reserve, a first actuator (6) which is integrated in the inner casting (5) and which authorizes the flow of air to the outer casting (3) for inflation purposes, a second actuator (8) which is integrated in the outer casting (3) and which authorize the release of air to the outside for deflation purposes; an electronic assembly which can send information to one or other of the actuators (6, 8) and/or receive the information delivered by the detector(s) (7, 9) in order to control the pressure and the temperature in the outer casting (3) and/or in the inner casting (5), a mean for controlling said electronic assembly and a keyboard.
The inventive system is suitable for vehicles.
