Abstract

Válvula de retención perfeccionada. De acuerdo con la presente invención, una tapa que presenta una abertura de entrada se acopla periféricamente a un cuerpo que define un hueco. Una arista se extiende a través de este hueco y sostiene un diafragma flexible contra la tapa, sustancialmente a todo lo largo de la arista. El diafragma se acopla contra la tapa para cerrar la válvula, mientras que los borde periféricos del mismo se doblan separándose de la tapa para abrir la válvula cuando se ejerce una presión fluida predeterminada en la abertura de entrada. En la versión ilustrativa, la abertura de entrada y la de salida son generalmente circulares y el cuerpo define un hueco semiesférico. La arista es solidaria del cuerpo y se extiende diametralmente a través del hueco. La longitud de la arista es superior a su anchura y divide sustancialmente el hueco del cuerpo en dos cámaras sensiblemente iguales, pero definiendo un paso en comunicación con el taladro de la abertura de salida. En la versiónilustrativa, el diafragma es un disco dotado de un diámetro sensiblemente igual a la longitud de la arista y de un grosor inferior al 20% del diámetro y también inferior a la anchura de la arista. En la siguiente descripción y en las reivindicaciones se ofrece una explicación más detallada de la invención, que se ilustra en los adjuntos dibujos.
