Abstract

Improved safety valve for the discharge and replenishment of a fluid, such as air and/or gas and/or liquid, applicable to the crankcase of submerged electric motors or the like, characterized essentially by the fact of comprising a cylindrical body provided in its interior of a fluid passage hole that connects a bottom wall of said body with an annular discharge provided in such body, inside which discharge is threaded a first rubber ring provided with a lip that rests on a wall circumferential of the annular discharge and is apt to press mostly on said wall or to separate from it with the corresponding closures or opening of the orifice through the annular discharge.
