Abstract

Válvula de seguridad y método para su fabricación. La válvula se emplea para aliviar la sobrepresión en el compartimiento de pasajeros de un vehículo automóvil y tiene mariposas de válvula que están retenidas en conexión con un alojamiento mediante regletas retenedoras moldeadas in situ. La válvula se fabrica un útil de moldeo por inyección que tiene un par de mitades de molde que definen una primera cavidad de molde para formar el alojamiento y una segunda cavidad para formar las mariposas. Una vez que el alojamiento y las mariposas han endurecido, se abre el molde, permaneciendo el alojamiento en contacto con una mitad del molde y permaneciendo las mariposas en contacto con la otra mitad del molde.
