Collapsible filters of the Rusakova system. The utility model relates to the field of engine building and can be used in the restoration of used filters, as well as in the manufacture of collapsible filters for cleaning 1W.cl., fuel in engines, internal combustion and other filters. Known filter design / see M.A. Grigoriev Oil and fuel purification in tractor engines publishing house Mapleteostroy M 1U70, page JL59. The Schiltre contains a housing with a pressed-in nut, wherein the inner cavity is made in the housing with a filter element razmepti in it, shut-off and by-pass valves. This design has several disadvantages. When installing the removal of the filter from the engine, a lot of effort is required. For reliability of sealing the cover with a nut, special glue is used or a rubber ring is installed, which requires a check for tightness of this connection. The tightness of the filter and the cover is achieved by rolling with glue when heated. The purpose of this model is to simplify the design of the filter and its manufacturing technology, ensure the reliability of filter sealing and use old used ones for restoration to produce new collapsible filters. This goal is achieved by using a housing with a collar under the gasket and covers from the {used old filter, using gaskets to seal the filter of the cover and housing, and also sealing the filter on the engine block, using a spacer made in the form of a STE. MPO ring with a recess under a ring of collar and a collar of 4-5 gm. around the perimeter, as well as the presence of a nut on a No. Ш, е case with a different one, which ensures the necessary tightening of the filters. on the fitting. In the drawing, a collapsible picture is shown: oil filter, general view and section. The filter contains a housing D / with a collar 2, a housing jutter, a cover 3 with a diameter equal to the inner diameter of the housing with a threaded center. / Hole, a gasket (, 4,; in the housing there is a filter element .5, a bypass valve, a shut-off valve (7, / a spacer 8 is applied to the filter, made in the form of a stamped ring with a shoulder along the outer perimeter. On the bottom of the filter housing, a nut is welded from the outside to the center.

 //,

cavity 12, and the clean daslo, passing through the filter element 5, enters the lubrication system.

Thus, the proposed technical grid allows} T1 to increase the filter design, and also the technology for its manufacture. If the collar is carried out on the engine block, then the spacer and the rubber ring disappears.

The sealing of the filter housing with the housing and the filter with the spacer is achieved by laying and tightening the filter on the engine fitting with a weld welded on the filter bottom. The CBoetr gasket, with its lower surface, is pressed against the filter cover and the upper against the shoulder of the filter housing and to the spacer. The filter cover is made with a diameter equal to the inner diameter of the filter housing, and since the edge of the filter housing is rolled by i, 5-3 goes inside the housing, the cover is inserted into the housing and removed from it by deformation of the metal of the filter housing. Filters of the proposed design can be made from old waste by restoration. During the restoration of used fixed filters, the sealing roll of the housing and lid is cut off, the housing is washed, the cut edge of the filter housing is bent 2.5-3 cl inside the housing, a nut is welded on the bottom of the housing. The filter is filled with parts, the cover from the old filter is inserted, the gasket is wound between the cover and the shoulder of the housing and the filter is assembled. A filter restored in this way becomes collapsible for reusable use.

The spacer is made in the form of a stamped ring with

the recess under the rubber ring of the conical section and around the perimeter has a collar with a height of 4-5 shd, and the inner diameter of the spacer is equal to the outer diameter of the filter housing.

According to the principle of this model, it is possible to produce fuel and other filters with a small internal pressure / hum. Then about 1 ltr can be screwed onto the fitting, clinging to a smooth plane and a collar under the rubber ring on the spacer is not required.

Prototypes are installed and tested in work on the author's car.
