Description

The invention relates to engine building and can be used in the lubrication system of an internal combustion engine.

Known oil pallets of engines containing side walls and a bottom with a drain and magnetic plug, an oil intake, the design of which is very simple, but does not prevent splashing of oil, which is supplied to the lubrication system along with mechanical impurities washed out of friction pairs, and the magnetic filter can only hold impurities of magnetic metals (Mikhailovsky E.M. et al. Automobile device-M., 1987, pp. 23-27, AK Bolotov and others. Design of tractors and automobiles-M., 2008, p. 106).

An ICE oil pan is also known, comprising side walls and a bottom with an oil collector in the form of a recess, a drain plug, an intake device, a vertical filter baffle separating the oil pan into two cavities, and a guide plate mounted between the engine crankcase and the oil pan inclined towards the crude oil (RU No. 2067200, publ. 09/27/1996).

Closest to the technical nature of the claimed device is the selected as a prototype oil pan of an internal combustion engine, containing side walls, a bottom with an oil collector in the form of a recess, drain and magnetic plugs, a suction device, a vertical filter baffle separating the pallet into the cavity of the cleaned and uncleaned oil guide plate mounted with a slope towards the crude oil, in which the filter baffle is installed in horizontal guides with a clearance of m between the bottom, and in the lower guide is installed regulating the gap damper (RU No. 2597731 publ. 08.24.2016).

A disadvantage of the known sump is that during maintenance and oil change is necessary to remove the control flap, as it prevents the discharge of waste oil from the sump.

The problem solved by the present invention is to reduce the complexity and improve convenience during maintenance of the internal combustion engine.

This problem is solved in that in the oil pan of an internal combustion engine containing side walls, a bottom with an oil collector in the form of a recess, drain and magnetic plugs, a suction device, a vertical filter baffle dividing the pan into the cavity of the cleaned and uncleaned oil, a guide plate installed tilted towards the crude oil, regulating the valve under the vertical filter baffle mounted in the lower horizontal guide, the latter is additionally made with a single slot and is equipped with elastic elements in the form of curved plates fixed with an upper edge to the walls of the slot, and the base of the control flap is made conical.

и обеспечивая полный слив масла при его замене. К тому же, выполнение упругих элементов в виде выгнутых пластин, закрепленных верхней кромкой на стенках прорези, а основания регулирующей заслонки конусным, надежно обеспечивает требуемую и равномерную по высоте величину зазора

.The implementation of a horizontal guide with a longitudinal slot provided with elastic elements makes it possible to regulate the valve when removing the vertical filter baffle spontaneously, that is, under the action of the elastic elements, to rise, forming a gap between the bottom of the pan

and ensuring complete drainage of oil when changing it. In addition, the implementation of the elastic elements in the form of curved plates fixed by the upper edge to the walls of the slot, and the base of the control flap conical, reliably provides the required and uniform height clearance

.

Comparison of the proposed solutions with analogues and other known technical solutions in this field revealed the signs that distinguish the claimed solution from the prototype, which allows us to conclude that the criterion of "significant differences".

In FIG. 1 shows an oil pan, a cut.

In FIG. 2 is a section BB of FIG. one.

In FIG. 3 is a section GG in FIG. 2, where a, b - vertical control valve in the pressed and raised state, respectively.

The oil pan contains a guide plate 1, inclined to the side of the crude oil, the side walls 2, the bottom 3, the drain magnetic plug 4, the intake device 5, a vertical filter baffle 6 installed in the upper 7 and lower 8 horizontal guides and dividing the pan into the cavity crude A and purified B oil, a regulating valve 9 with a conical base 10, located under the vertical filtering partition 6 in the longitudinal slot 11 in the lower guide 8 and tightly adjacent to the side walls 2 (f 1 g).

On the vertical walls 12 of the slots 11 are fixed by the upper end 13 curved elastic elements 14 (Fig. 3).

A groove 15 is made in the side wall 2 for installing the vertical filtering partition 6 and the regulating flap 9. On the outside of the side wall 2 above the groove 15 with screws 16, a plate 17 with a seal 18 is fastened, pressing the vertical filtering partition 6 against the inner surface of the opposite side wall 2 (Fig. . 2).

When the engine is running, the oil drained from the friction pairs enters the guide plate 1 and flows into the cavity formed by the side walls 2, the bottom 3 and the vertical filter baffle 8, into the cavity of the crude oil A (Fig. 1). In this case, the control flap 9 is located between the walls of the slot 11, is located vertically and overlaps the gap between the lower guide 8 and the bottom 3 (Fig. 3a). From cavity A, the oil passing through the vertical filtering partition 6 is cleaned of light impurities and enters the cavity of the purified oil B, and heavy impurities settle on the bottom 3 in cavity A. From the cavity B, the purified oil enters the intake device 5.

During the maintenance of the engine, the magnetic drain plug 4 is unscrewed and the oil is drained from the cavity B of the sump.

(фиг. 3б). Скольжение упругих элементов 14 выгнутой поверхностью по конусной поверхности 10 регулирующей заслонки 9 происходит в масленой среде легко (без трения). Затем оставшееся масло (находящиеся ниже уровне нижней направляющей 8 и нижней кромки паза 15) из полости А через образовавшийся зазор

между днищем 3 и регулирующей заслонкой 6 (без ее выемки) сливается из поддона.Then the screws 16 are unscrewed, the plate 17 and the seal 18 are removed and through the groove 15 in the side wall 2 along the upper 7 and lower 8 horizontal guides take out the vertical filtering partition 6. At the same time, the elastic elements 14, in the form of plates, curved and fixed by the upper edge 13 on vertical walls 12 of the lower slot 8, raise the control valve 9 to a height

(Fig. 3b). The sliding of the elastic elements 14 with a curved surface along the conical surface 10 of the control flap 9 occurs easily in an oily environment (without friction). Then the remaining oil (located below the level of the lower guide 8 and the lower edge of the groove 15) from the cavity A through the formed gap

between the bottom 3 and the control flap 6 (without its recess) is drained from the pan.

After draining the oil, the sump is put into operation.

On the upper 7 and lower 8 horizontal guides through the groove 15 insert a vertical filtering partition 6, exerting pressure on the regulating flap 9, which, being between the walls of the slot 11 of the lower guide 8 and overcoming the conical base 10, the resistance of the elastic elements 14, is lowered and pressed against the bottom 3 . The groove 15 is sealed by fastening with screws 16 the plate 17 with the seal 18.

Thus, the oil is replaced without a recess, and consequently without installing the control damper 9 in the groove 11 of the lower guide 8. The exclusion of these operations, especially the installation of the regulating clearance of the damper, not only reduces time, but also increases the convenience of engine maintenance. In addition, the application of the proposed technical solution allows the use of a pan without a vertical filter baffle.
