SU100929A2 - Paper filter element for the cleaning of lubricating oil and diesel fuels - Google Patents

Description

The invention relates to paper filters used for fine cleaning of lubricating oil and

DIESEL OIL FUEL

Basically auth. St. No. 78051 described paper filter element, made in the form of an accordion.

The present invention is a further improvement of the paper filter element according to the author. St. No. 78051 n differs from the previous one in that the tube of the filter element is removable and the connection of the accordion with the tube is made by paper (or other) thin-walled tubes attached to the harmonica. To fix the petals of the filtering accordion inside the sump 15nut | The surface of the latter is equipped with a number of small protrusions.

 phage. 1 shows two paper filter patrols in two designs; pas figs. 2 - paper filter element assembled; in fig. 3 - oil filter sump; in fig. 4 shows a filter element tube.

The design and assembly of the proposed paper filter element is reduced to the following.

K. paper harmonica}, assembled in the form of a miogoluchevoy star, glued in the upper and lower parts of the short tube 2, made of wrapping paper :: (;; whether another material).

The accordion 1 glued to the paper connecting tubes 2. is put on the metal hole-shaped tube 3, the ends of the tubes 2 are bent into the inside of the tube 5. In such a form, the accordion together with the tube 3 is inserted into the rigid sump 4.

The sump 4 is provided on the inner surface with a series of small protrusions 5, prior to shear and following sections (individual accordions, as well as a ring 6 for sealing the sump in the filter housing.

The metal hole tube 3 and. Has on the outer surface helical grooves 7, for distribution. E1P: oils and 8 holes for the outlet of the cleaned oil.

The filter cartridge assembly, together with the sump, is inserted into the body of the engine oil filter without any alteration of the latter.

The filter operates as follows. Oil pumped by the pump is forced through the papers} into the individual harmonic lobes, leaving contaminating impurities on their surface. The cleaned oil moves the petals BHyTpt in the radial direction, goes into the screw grooves 7 of the tube 3, from where it passes through the holes 8 into the central tube of the oil filter and flows into the crankcase.

In the described filter, the replacement part is only a paper accordion. The remaining parts — settler 4 and tube 3 — are constant. As a result, the design of the filter element is simplified, and the material consumption to

labor on its manufacture is greatly reduced.

Subject invention

Paper filter element for the cleaning of lubricating oil and diesel fuels according to ed. St. No. 78051, characterized in that, in order to simplify the filter, the central tube of the filter alement is made removable with the connection of this tube with an accordion using paper (or other) thin-walled tubes attached to the accordion, and in order to fix the petals of the filter accordion inside the sump, The inner surface of the latter is made numerous small protrusions.
