Definitions

• Oil cleaner for equipment and vehicles with combustion engine Oil cleaner for equipment and vehicles with combustion engine.
• the invention relates to an oil cleaner or purifier of the kind stated in the introductory part of claim 1.
• Lubrication oil in combustion engines is contaminated by particles ⁇ fuel, water and other fluid, material reducing the lubricating effect and causing engine wear.
• German Patent Specification 464504 it is known an oil cleaner wherein the oil in addition to be heated also is placed under a vacuum by connecting a evaporating chamber to the inlet system of the engine to extract volatile parts with a boiling point superceed- * ing that of oil.
• This and corresponding other known oil cleaners for use in vehicles have a disadvantageous heating member structure.
• the main object of the invention is to provide ah oil cleaner with an efficient exchange member to achieve a satisfactory devapourization with an oil cleaner which is simple to manufacture.
• Another object is to provide an oil cleaner with an outer shape suitable for mounting in the engine compartment of vehicles and small wessels, respectively.
• the oil cleaner in this embodiment is based on a pot shaped carrier 11 which is closed upwardly by an outer cover or lid 12 and an inner cover 13, both of which are bell shaped and having a rim, 14 and 15 respec ⁇ tively, which are clamped against the flange 16 of the carrier over a sealing ring 17.
• the main elements of the oil cleaner is an annular manifold 18, two conically arranged helical heat ⁇ ing members 19 and a corresponding conically shaped, evaporating member 20, with lamels.
• the manifold pipe 18 is arranged horizon- tally under the inner cover 13 and is provided with a series, in the shown example 36, downwardly facing outlet openings.
• the manifold 18 is connected to an inlet pipe 21 conducting contaminated oil to the oil cleaner from one or more filters. To bring the oil through the outlet openings, it has to be supplied with a certain hydraulic pressure, e.g. by a not shown pump.
• the lubrication oil may be extracted from the main oil conduit of an engine, by inserting a T-pipe at the side of the oil pressure
• the heating helixes 19 are arranges in two sets, adjacent to each other in a mutual distance.
• the heating helixes are fed by a supply pipe 22 with a bifur ⁇ cation 23, and is emptied through a corresponding bifur ⁇ cation 24 to an outlet pipe 25.
• the supply pipe 22 and the outlet pipe 25 are suitably connected to the cooling system of the engine to which the cleaner is applied.
• the evaporating member 20 is arranged in the interspace between the two sets of heating helixes 19,
• the evapora ⁇ ting member 20 consists of a series of lamels 26 being attached at its outer end to an annular member 27 resting on the bottom of the carrier 11.
• the lamels 26 are suit- able arranged in shingle shape, i.e. with an overlap.
• a suction conduit 28 is connected to the inlet manifold (not showh) of the engine.
• an oil remover is arranged in this conduit.
• a pipe 29 to introduce pure air through an adjustable automatic vacuumvalve is arranged.
• This valve will provide a vacuum in the oil cleaner, which reduces the relative moisture in the inner of the oil cleaner, thus removing water from the oil passing the evaporating member 20.
• a vacuum of 480-540 mm Hg will expand the air introduce.to three ti es its original volume.
• the relative water content will be reduced correspondingly.
• water removed from the oil cleaner wil-more easily be transferred to the adjacent air.
• An oil cleaner according to the invention is being tested at a testing institute and following measurement have been made under operating conditions. changes from to Particles mg/kg 86 , 9 12 , 57 n-pentanc unsolvable weight %
• the present oil cleaner can be mounted in common passenger cars, as it can be produced with relatively simple and inexpensive parts.
• the parts of the cleaner may mainly be manufactured pf plastic materials, which allows most cost reduction on mass production.
• the field of usage will:also incorporate busses, trucks, motorized construc ⁇ tion equipment, ships engines, tooling machines, hydrau ⁇ lic apparatus, transformers and " various plants with a combustio -engine.
