摘要

A safety valve for air chambers of pneumatic tires, essentially characterized by the fact that it consists of a fully threaded shank, partially covered by a truncated cone-shaped rubber body slightly larger in diameter than the rim hole to which it is fixed by compression, and a metal bushing, having the smaller diameter slightly larger than the hole of the rim, on which its bases rest, which entirely covers the above-mentioned rubber body, which is fixed in position by means of a nut which is screwed into the piston rod.
