Abstract
Valve with in-built pressure threshold detection, mounted in an engine block pipe, the valve comprising a body comprising an electrically insulating external element (16) and an electrically conducting internal element (18) bearing the obturator seat (14), an obturator (12), the valve also comprising an electrical terminal (34) connected to a detection system which, with the engine block (4) and the internal element (18), forms an electric circuit, the internal element (18) being in permanent contact with the electrical terminal (34), the internal element (18) sliding in the external element (16) such that, for a pressure below the threshold pressure, the internal element (18) is in electrical contact with the engine block, closing the electric circuit, and for a pressure equal to or greater than the threshold pressure, the internal element (18) is not in electrical contact with the engine block, breaking the electric circuit.
