Abstract: The invention concerns a controlled pneumatic valve (1), for remote inflating and deflating of a capacity (2), comprising a membrane (17) maintained between a valve body (18), including orifices (24) and a cover (19); and defining with said cover a control chamber (20) and with the body an escape chamber (21), the latter being capable of being connected with the capacity (2) for deflation when the check valve (28) is thrust by levers (32) inverting the direction of movement of the membrane (17) sucked towards the cover (19). By the action of a pressure in the control chamber (20), the membrane (17), bearing a cup (33) with an annular conduit, moves towards the body (18), isolates the escape chamber (21), and opens the check valve (28) by direct thrust to perform inflation. The inventive device is particularly designed to control and adjust tire pressure.

Abstract: The invention relates to a controlled pneumatic valve intended for the remote control of the inflation and deflation of a volume, comprising a membrane held between a half-body and a grooved ring. The membrane delimits a pilot chamber with the half-body and an exhaust chamber with the grooved ring. Said exhaust chamber communicating firstly with a bore opening out into the volume and secondly with the pilot chamber by means of a non-return valve housed in a body. The pilot chamber is connected to a high-low pressure circuit via an intake piece. Said non-return valve pushes the membrane in order to close the bore. The pneumatic valve comprises a mechanical means which is controlled by the membrane and which is used to open the non-return valve, in addition to the action of the pressure, at low pressure. Said means comprises a bridge that is fixed to the membrane and a finger which is disposed opposite the non-return valve. The invention is suitable for low-pressure tire control.
