Fuel supply tube for internal combustion engine

摘要

A device for reducing contaminating components in the exhaust gases of combustion engines, that comprises an airtight chamber (1) equipped with an entrance and exit orifice (6,7), located opposite one another, between whose orifices there are arranged, within the chamber (13), two pistons (8,9) and an intermediate compression spring (12). Each piston has an axial through hole (10,11). The diameters of both pistons are different from each other and the diameter of their respective through hole (10,11) is smaller than the diameter of the entrance and exit holes.
