Abstract
1. Un dispositivo de alivio de presión, particularmente destinado a un transformador de potencia, que tiene un miembro de cierre de válvula destinado, en situación asentada, a mantener un fluido a presión en un recipiente, teniendo dicho miembro de cierre de válvula una parte de pestaña que se extiende hacia abajo desde su periferia, y un anillo de nivel que tiene una junta acoplable con el miembro de cierre, caracterizado porque tiene una junta plana montada en un rebajo hecho en el anillo de nivel, teniendo dicha junta plana una parte extrema flexible, dispuesta para su aplicación con frotamiento a una superficie interior de la parte de pestaña. 2. Un dispositivo de alivio de presión, según la reivindicación 1, caracterizado porque la anchura de la zona exterior del rebajo para la junta es mayor que el espesor de la junta plana. 3. Un dispositivo de alivio de presión, según la reivindicación 2, caracterizado porque la superficie superior del rebajo para la junta es plana. 4. Un dispositivo de alivio de presión, particularmente destinado a un transformador de potencia.
