INFLATION PRESSURE CONTROL VALVE OF A TIRE FOR A DEVICE FOR ADJUSTING THE PRESSURE OF THE TIRES OF A VEHICLE DURING THE MARKET

摘要

P This valve is particularly robust and long-lasting thanks to the absence of a membrane between the pressure of the tire and the atmosphere. / P P It has a valve 50 with a seat 16 integral with the body of the valve and with which cooperates a valve 26 fixed on a control piston 21. The latter is exposed to pressure on two faces 24, 25 opposite and loaded in the direction of closure by a spring 29. The action of this spring is countered by a discharge force from a movable surface 42 urged by the pressure and separating a pressure chamber 33, receiving the pressure of the adjusting device, a discharge chamber 34 connected to the atmosphere or in which is empty. / P
