Abstract
Check valve, which is specially designed to be interposed in hydraulic brake circuits of vehicles, in order to prevent the entry of air into the brake fluid conduits, essentially characterized in that the valve body has centrally a portion of the conduit of the brake fluid. Smaller section than the lateral portions, there being in said central portion a steel ball, permanently pressed by a bushing on which an expansion spring acts, forcing the ball against a rubber ring that is wrapped by a bushing on which it acts a second expansion spring, opposite to the first, it being provided that such a rubber ring, when the valve is at rest, is maintained. On an annular seat that delimits the entrance to the central portion of smaller diameter of the valve body, all in such a way that the hydraulic pressure sent through the rubber ring, acts on the steel ball, against the force of the. First spring, and the liquid is directed towards the brake cylinders, while at the end of the overpressure, the liquid recoil inside the valve is made until the greater tare of the second spring causes the rubber ring to close against its seat, leaving a pressure higher than the one in the entrance area in the liquid outlet area.
