Check valve, especially for liquids, which is essentially characterized by being constituted by a tubular body interleaved in the corresponding conduit to be controlled and intended for the entrance, at one end, of the fluid coming from a supply point and at its exit, by the another extremity, towards the point of consumption or use, having inside said body a seat to which an elastic O-ring is applied with which a conical obturator cooperates with a guide rod and subjected to the action of a suitable spring, the tip of such shutter being directed towards the inlet mouth and the opening of this valve having effect, by the pressure of the fluid, while its closing occurs automatically by the action of that elastic means, possibly favored by the pressure of the fluid that may attempt to return to the point of supply.
