Abstract
Official abstract text for this publication.
Measurement equipment for measuring the inflation pressure of a tire of a vehicle wheel 1 . The equipment comprises a body 16 defining an internal volume, a communication orifice 19 for putting the inside volume of the body 16 into communication with an inflation chamber situated between a rim 2 and a tire of the wheel and containing an inflation gas and an indicator member 25 slidably mounted in the body 16 so as to define a gastight separation between a first chamber 26 containing a given quantity of a reference gas and a second chamber 27 into which the communication orifice 19 leads. As a result, the indicator member 25 is subjected to opposing pressures that exist in each of the chambers. A position-identification device 30 is operative to identify the position of the indicator member in the body.
