摘要

Indicator device for maximum pressures in internal combustion engines, characterized in that an inlet conduit connects the cylinder of the engine with a sphere located between two circular seats, one of which is normally supported by the action of a central rod that , passing through a helical spring, is connected to one end of this in a rotating manner, while the other end of the spring is joined integrally to an externally threaded bushing which, provided with a flap that slides inside a vertical groove of a hollow handle, is screwed, in a ring of a fixed main body, at the instance of the turns of said handle, inside which the spring, the bushing and the rod are housed, turns that are recorded in a turn counter placed in the fixed main body, inside which is a device for locking the rotating hollow handle, as a function of the displacement experienced by the sphere first of all at the request of the engine pressure.
