Abstract

Perfeccionamientos introducidos en las válvulas de membrana para electroválvulas, en especial para máquinas lavadores; del tipo en las que una membrana elástica, reforzada en su centro por un platillo de material rígido, forma por un lado la válvula de cierre de paso de agua, y por la parte opuesta forma una cámara de presión, de modo que el cierre y la abertura de la válvula se verifican al establecerse respectivamente una presión o una caída de presión en el interior de la cámara de presión, determinandose el establecimiento de la presión o de la caída de presión, mediante un elemento obturador de paso entre dicha cámara de presión y la descarga de la válvula, caracterizados por el hecho de que el platillo, acoplado con la zona central de la membrana, se halla dotado de una descarga periférica que, en el acoplamiento con dicha zona de la membrana, forma un canal anular que comunica con la cámara de presión a través del movimiento del tabique flexible periférico de la membrana, estando previstos unos pezoncillos distanciadores para mantener abierto dicho canal, que a su vez comunica con un canal anular, practicado en la superficie de la parte de la membrana, que se halla en contacto con dicho platillo.
