Abstract

1. The amplifier cover of the oil filter containing a disk-shaped base with a Central threaded channel for connecting and supplying oil to the engine and holes for oil to enter the filter, characterized in that in the upper part of the outer cylindrical surface of the Central threaded channel protrusions are made to provide installation fixation of anti-drainage parts valve by attaching to them the base of the filter element of the anti-drain valve. 2. The amplifier according to claim 1, characterized in that the height of the protrusion corresponds to the difference between the inner diameter of the base of the filter element of the drainage valve and the outer diameter of the central rifled channel, expressed by the equation: h = D - d, where h is the height of the protrusion, D is the inner diameter of the base of the filter element anti-drain valve, d is the outer diameter of the Central rifled channel.

Description

The invention relates to the field of engine building and is intended to work in the lubrication systems of internal combustion engines, in particular, in various designs of oil filters.

There are known designs of oil filters containing the following main elements: a housing, a cover with an amplifier, a filter element and a bypass and anti-drain valve (Ukrainian patent No. 1413, MKI VO1D 35/14).

As anti-drainage valves, rubber or a valve in the form of a diaphragm, a spring compression ring and a filter element base are most often used. The use of a prefabricated anti-drain valve is preferable for use in oil filters, but during assembly of the filter increases its complexity.

There are known constructions of an amplifier for an oil filter cover containing a disk-shaped base with a central threaded channel for connecting and supplying oil to the engine and peripheral holes for oil to enter the filter (B.V. Ershov, M.A. Yurchenko “VAZ Cars Design and maintenance, Kiev, “The Ppsol's Vishch 1983).

A disadvantage of the known design is that it has a low mounting ability of the filter anti-drain valve. during assembly with filter parts and disposal of waste parts The invention is based on the task of publishing such a design

the amplifier, which would ensure its high mounting ability with parts of the anti-drain valve, improves the disposal process.

The problem is solved in that in the amplifier a disk-shaped base with a central threaded channel for connecting and supplying oil to the engine and peripheral holes for oil to enter the filter, according to the invention, protrusions are made in the upper part of the outer cylindrical surface of the central threaded channel to ensure installation fixation on it parts of the anti-drainage valve by securing the base fsh1tryush; its element.

The number of protrusions may be different, but not less than two, with a preferred arrangement relative to each other at an equal distance.

The height of the protrusions should correspond to the difference in the inner diameter of the base of the filter; its element of the anti-drain valve and the outer diameter of the central rifled channel, expressed by the equation:, where

h is the height

D is the inner diameter of the base of the filter element

anti-drain valve;

d is the outer diameter of the central rifled channel.

The drawings show the design of the inventive cover amplifier

oil filter.

Figure 1 shows a General view of the amplifier in section. On the “FIG.

The amplifier of the oil filter cover contains a disk-shaped base 1, a central threaded channel 2 for connecting and supplying oil to the main oil line of the engine.

The outer cylindrical surface of the central threaded channel 2 is made of blades 4, depreciating the installation fixation on it of the parts of the anti-drainage clat, consisting of a diaphragm 5 made in the form of a rubber disk, a compression ring 6, a spring 7 and the base of the filter element 8.

The assembly of the amplifier with parts of the anti-drainage clan is as follows.

On the protruding central threaded channel (2) of the amplifier with a disk-shaped base 1 and holes 3, a diaphragm 5, a compression ring 6, a spring 7.

Thus, a fixed connection is obtained between the amplifier of the oil filter cover and the parts of the anti-drain valve, which is then used, for example, when assembling (disassembling) the filter as a single unit. There is no need for preliminary fixation of parts of the anti-drainage valve with an amplifier by means of special devices, for example, crackers.

Compared with the prototype, the claimed design of the amplifier cover oil filter allows you to solve the claimed technical result.

The design of the amplifier has novelty, inventive step and industrial applicability and can be protected by a patent of Ukraine.
