Abstract

Una válvula unidireccional, en la cual la válvula comprende un cuerpo de válvula que incluye un armazón, una abertura de válvula a través de dicho armazón y un asiento de válvula que se extiende desde el armazón y que rodea al menos parcialmente la abertura de válvula. La válvula también incluye una tapa de válvula que tiene una primera parte unida al armazón y una segunda parte adyacente libre para desplazarse desde una primera posición, donde la segunda parte está en contacto con el menos parte del asiento de válvula, hasta una segunda posición donde al menos parte de una segunda parte está separada del asiento de válvula, en la cual la tapa de válvula tiene un perfil contorneado. El perfil contorneado puede extenderse a lo largo de la longitud de la tapa de válvula, entre el punto de unión de la tapa con el armazón y el extremo de la tapa, o desde un extremo lateral de la tapa hasta un segundo extremo lateral.
