ES280186U - Oil filter for internal combustión vehicle engines (Machine-translation by Google Translate, not legally binding) - Google Patents

Abstract

Oil filter for engines of internal combustión vehicles, of the type constituted by an external body endowed in the center of its base with an axial oil inlet to filter, which enters through the lower part of a cartridge of filtering material, which is found arranged above the bottom surface and whose upper part defines an evaporation chamber with a closing cap of the filter body; so that the oil leaves the cartridge through openings that have a washer with concentric steps, in which chamber the liquid impurities that carry the oil to the outside evaporate, while the filtered oil leaves without pressure by a lateral mouth made in the filter body at the height of the camera; characterized in that from the bottom of the filter body a receptacle emerges axially inside which the filtering material is arranged between two end grids, one the upper one, has projections that abut against the threaded cap of the filter, while the receptacle at its start with the the bottom has a thickening provided with a drill perpendicular to the axis of the filter in which there is arranged a conduit defining a lateral and inferior entry of the oil to be filtered, which part of it enters the cartridge by means of an intermediate tap centered with the axis of the cartridge, while the rest of the oil has been led to an exit facing the entrance; while the filtered oil leaving the cartridge decays when it falls through stepped surfaces that emerge integral with the cartridge surface; and because the oil falls to the bottom of the filter where a suction is produced in its outlet which causes an oil outlet pressure.
