Abstract

Perfeccionamientos en válvulas de fluido, del tipo que se dota a cada válvula de una lumbrera de fluido; un asiento de válvula alrededor de la lumbrera y medios de cierre móviles hacia el asiento y en sentido contrario, caracterizados porque comprenden medios de cierre una superficie de obturación acoplable con el asiento y una protrusión que se extiende desde la superficie de obturación hacia el asiento, actuando la protrusión para crear un flujo acelerado de fluido entre el asiento y la superficie de obturación antes de que se ésta última se acople al asiento al moverse el dispositivo de cierre hacia el asiento y estando destinada además la protrusión, al menos en parte de la misma, a ser empujada en acoplamiento hermético con las partes circundantes de la lumbrera por presión en la válvula cuando la superficie de obturación se acopla al asiento.
