Abstract

Improvements introduced in filtering systems, applicable to internal combustión engines, characterized in that they consist of providing a filtering device, of the type normally used for this purpose, with a deflector, whose main mission is to eliminate air bubbles or gas that originate in the fuel filtering process, and that, as it happens, happens to the injectors and pumps of the engine, a series of failures and turbulences occur that hinder and hinder the proper functioning of the machine, in such a way that the assembly that provides the use of the deflector in which the stated improvements consist, avoids such inconveniences, supposing that it is mounted superiorly to the mass of the filtering product, specifically in the lid of the filter itself, for which takes the form of a hollow cylinder devoid of its upper base and of a circular central portion in the lower base, the liquid, devoid of impurities, but not of bubbles, it will ascend through the external part of the lateral surface of the deflector, to then descend, by gravity, to the bottom of the latter, at which time the bubbles, due to their lower density and weight, will try to occupy an elevated position, so that they will completely abandon the sine of the filtered fuel, and by a suitable superior conduction they will be able to evacuate to the outside, that is to say to the return pipe, whereas the liquid, already in suitable conditions to fulfill its mission, will be forced to travel the axial and then radial duct that includes the lid itself, where it will leave the filter and pass to the injector pumps.
