Abstract

Safety valve, constituted by a shutter body, axially movable inside a fixed bushing and coupled to a drive pin provided with an adjustable pressure spring, characterized in that said shutter is formed by a front part in correlation with the embouchure of the body for the exit of a pressurized fluid, and on the one hand cylindrical part sliding inside the said guide sleeve, having in the said front part a protruding annular relief corresponding to an annular seat of the aforesaid embouchure, determining the closing position of the valve, and of an incoming annular relief, concentric with respect to the previous one and of larger diameter, which faces a peripheral projection of a deflector nut mounted on the expressed embouchure, so that between the obturator and the embouchure cited an annular cavity is formed, limited by the respective concentric elements, opened through a outer gap formed between the incoming relief of the obturator and the projection of the embouchure, so that upon opening of the valve by the thrust of the fluid, overcoming the opposition of the adjustable spring, the obturator is separated from the seat and said cavity receives a volume of fluid that exerts an additional effort on the obturator that activates its separation.
