Abstract

1. Válvula de retención de fluidos líquidos y aeriformes, caracterizada porque está constituida por un cuerpo tubular, formado por dos elementos metálicos roscados entre sí, en cuyo interior y a lo largo de su eje, se mueve el obturador compuesto por los dos elementos (43 y 42) huecos y solidarios cuyo interior incorpora aletas (44), provisto de junta anular de estanqueidad (45) y empujado por un muelle (46) dispuesto en la cavidad (47) por la que pasan los fluidos. 2. Válvula de retención de fluidos líquidos y aeriformes, según la reivindicación 1, caracterizada porque la junta de estanqueidad se dispone en un asiento anular formado en la tapa anterior del cuerpo cóncavo contra el que actúa el respectivo extremo del obturador móvil. 3. Válvula de retención de fluidos líquidos y aeriformes.
