Manometric safety valve enables tire pressure to be obtained in relation to position of cup as function of spring elastic property and its color visible through transparent valve body

摘要

The manometric valve enables obtaining the pressure of a tire in relation to the position of the cup (F) as a function of the elastic property of the spring (I). It indicates the tire pressure as a function of the color of the pressure sensitive spring and visible through the transparent valve body (A'). It enables the pressure to be obtained relative to the position of the index (K') integral with the cup through the transparent plug (H').
