摘要

A device that allows to control the operation of the internal combustion engines, characterized by being essentially constituted by a hermetically closed cylindrical chamber, the closure being produced, in its upper part, by an elastic membrane solidly attached to the walls of the container by its edge, and whose membrane is provided at its center with an oval reinforcing piece, between which, and the lower base of the chamber, a recovery spring has been arranged.
