Abstract

Perfeccionamientos en mecanismos de soltura, de seguridad, caracterizados por usarse para soltar un órgano de un elemento acoplado, en condiciones determinadas, y porque el mecanismo de soltura está asociado con un espacio cerrado en una parte del elemento; el mecanismo es accionable para soltar el órgano del elemento acoplado, como resultado de cambios de presión y temperatura entre el espacio cerrado y el espacio que rodea al órgano.
