Abstract

The utility model discloses a recovery filter for engine oil of an internal combustion engine, which comprises an upper cover and a lower shell, wherein an oil inlet hole, an oil outlet hole and a by-pass valve are arranged in the upper cover. The utility model is characterized in that a cylindrical filter core which is composed of an outer filtering sleeve, an outer cylinder, a middle cylinder, an inner filtering sleeve and an inner cylinder is arranged in the lower shell; medicine is filled between the outer cylinder and the middle cylinder. The utility model can filter impurities in engine oil, and can keep performance parameter of the engine oil chronically stable through the chemical reaction of friction of the engine oil and the medicine. The utility model has the advantages that the engine oil does not need to be changed, the period for the major repair of an engine is extended, and the medicine can be conveniently replaced. The utility model is suitable for the internal combustion engines of an automobile, a tractor, etc.

Description

I. C. engine oil regenerative filter cleaner

The utility model relates to internal-combustion engine arrangement, especially relates to the oil renewal formula filter cleaner that a kind of internal-combustion engine uses.

The filter core of the oil filter of internal-combustion engine use at present mostly is the papery filter core greatly, its function singleness, only can the filter well cuts, can not stop the aged deterioration in the machine oil using process, behind the engine running certain hour, engine oil quality meeting severe exacerbation is to the stage that can not use, so motor in operation process, needs the machine oil of its lubrication system of periodic replacement, and generally all outwells with the machine oil of crossing, both caused the waste of machine oil, again befouling environment.

The purpose of this utility model be to provide a kind of can not only the filter well cuts, and can keep that the machine oil performance parameter changes in the internal combustion engine operation process, make internal-combustion engine realize that lubrication system does not need more change engine oil in allowed band.Can prolong the I. C. engine oil regenerative filter cleaner in engine overhaul cycle.

The purpose of this utility model is achieved in that the utility model comprises loam cake and lower casing, loam cake and lower casing are fixed together by center bolt and hexagon nut, the sidewall of loam cake has spaced-apart oil inlet hole and oil outlet, be processed with vertical by-pass hole at the top of loam cake, steel ball in the by-pass hole, spring and valve seat constitute bypass valve, feature is the filter core that cylinder barrel shaped is installed on the spring seat in lower casing, pass center bolt in the middle of the filter core, the outer wall of filter core is the outer filter ruffle of crossing, the outer filter ruffle inwall of crossing is close on the outer cylinder body, the inner barrel outer wall is glued with the inner filtration cover, be filled with medicament between middle cylinder body and the outer cylinder body, outer cylinder body, middle cylinder body, the bottom of inner barrel is fixed on the base plate, the top is equipped with head cover plate, outer cylinder body, middle cylinder body, all be processed with circular hole on the inner barrel sidewall.

The utility model is because design has the cylinder barrel shaped filter core, and between outer cylinder body and middle cylinder body, be filled with the medicament that can suppress the machine oil aged deterioration, therefore it can not only the filter well cuts, the more important thing is the friction chemical reaction that is undertaken by machine oil and medicament, make machine oil " regeneration ", keep the machine oil performance for a long time (as kinematical viscosity, acid number.Moisture content, flash-point etc.) parameter changes in allowed band, so can realize not change engine oil more of lubrication system basically, only needs to replenish because of scaling loss.Leak the oil level that is reduced, and the carbon deposit of in-engine piston ring and piston skirt generation is softer, very easily washes, thereby improves the friction between piston and cylinder sleeve, reduce wear.Prolong the overhaul life of motor, therefore the utlity model has impurity screening, stablize the machine oil performance, prolong the engine overhaul cycle, simple in structure, that medicament is changed is convenient, clean easy, convenient and practical advantage, is suitable for using on the internal-combustion engine of equipment such as automobile, tractor, engineering machinery, boats and ships, generator set.

Fig. 1 is a structural representation of the present utility model.

The filter cartridge construction schematic representation of Fig. 2 for amplifying.

Below in conjunction with embodiment and contrast accompanying drawing the utility model is described in further detail.

The utility model comprises loam cake 1 and lower casing 4.The sidewall of loam cake 1 has spaced-apart oil inlet hole 3 and oil outlet 2, is processed with vertical by-pass hole 8 at the top of loam cake 1, and the steel ball 9 in the by-pass hole 8, spring 10 and valve seat 11 constitute bypass valve.Center bolt 6 passes lower casing 4 and loam cake 1.The top is fixed together loam cake 1 and lower casing 4 with hexagon nut 12, is with spring seat 7 in the bottom of center bolt 6, lower casing 4, and the filter core 5 of cylinder barrel shaped is installed on the spring seat 7, passes center bolt 6 in the filter core 5.The outer wall of filter core 5 is the outer filter ruffle 14 of crossing, the outer inwall of crossing filter ruffle 14 is attached on the outer cylinder body 15, the outer wall of inner barrel 21 is glued with inner filtration cover 20, the bottom of outer cylinder body 15, middle cylinder body 18, inner barrel 21 is fixed on the base plate 19, head cover plate 13 adopts with the top of inner barrel 21 and is threaded, and head cover plate 13 covers inner filtration cover 20 simultaneously.Middle cylinder body 18, outer cylinder body 15.Between middle cylinder body 18 and outer cylinder body 15, be filled with medicament 17, outer cylinder body 15.All be processed with circular hole 16 on the sidewall of middle cylinder body 18, inner barrel 21.The outer material of crossing filter ruffle 14 is a wool felt, and the material of inner filtration cover 20 is a canvas.

During use, machine oil enters filter cleaner from the oil inlet hole 3 on the loam cake 1, flows into downwards then in the lower casing 4, machine oil is by the outer filter ruffle 14 filtering impurity of crossing, by the circular hole 16 of outer cylinder body 15, with medicament 17 friction chemical reaction takes place again, machine oil passes the circular hole 16 of middle cylinder body 18 again.The circular hole 16 of inner filtration cover 20, inner barrel 21 flows to inner barrel inner chamber 22, flows out the inflow engine main oil gallery from oil outlet 2 then.When filter core 5 is stopped up by contamination, its inside and outside differential pressure increases, steel ball 9 in the bypass valve is by the engine oil pressure jack-up that makes progress, bypass valve is opened, most of machine oil just flows into oil outlet 2 by oil inlet hole 3, lower casing 4, by-pass hole 8, enter the motor main oil gallery then, to guarantee the required oil inlet quantity of motor main oil gallery.
