Abstract

The invention is intended to be used primarily in the lubrication systems of internal combustion engines and provides improved filtration quality by increasing the filter surface area to volume ratio occupied by the filter. To do this, at the ends of round plates 1 with grooves 2 and protrusions 3, grooves 5 are formed, which form a grid when intersecting with each other, and windows 4 in protrusions 3 have the form of sectors facing to the axis of the plates. 2 Il.

Description

1

The invention relates to mechanical engineering, in particular, to the construction of oil filters for internal combustion engines.

The goal is to improve the quality of filtration.

Figure 1 shows the plate, top view; figure 2 - section aa in figure 1

The slotted filter comprises a set of plates 1 having a circular shape with alternating radial grooves 2 and protrusions 3, in which windows A are made, having in plan the shape of sectors facing with their vertices to the axis of the plates. At the ends of the plates there are grooves 5, which form a grid when crossing each other. The plates are assembled in a package on the rod 6 with the grooves 7 in such a way that the windows 4 of the adjacent plates are aligned with each other and form cavities 8 communicated with a hole 9 in the cover 10 connected to the housing 11.

The filter works as follows.

The filtered fluid fills the housing 11 and through the grid of channels 5, open from the outside and from the side of the grooves 2

BUT

plates passes in the cavity 8 formed by the windows 4 and in the groove 7 of the rod 6. The filtered liquid from the cavities 8 is discharged through the openings 9 to the consumer. Particles contaminated with fluid whose dimensions are larger than the sections of the grooves 5. remain in the housing 11.

Claims (1)

Thus, the filter provides an increase in the ratio of the area of the filtering surface to the volume occupied by the filter, which improves the quality of filtration. Claims of the invention A slotted filter comprising a set of round plates with alternating external radial grooves and protrusions, in the latter of which windows are made, in that, in order to improve the quality of filtration, grooves are made on the end surfaces of the plates. forming at the intersection with each other grid, and the windows in the plan have the form of sectors, facing vertices to the axis of the plates. but. but.
