Abstract

The filter settler, including a cover with a hole for supplying fuel, with a central rod having a hole inside the rod for removing purified fuel, a glass with a drain hole closed by a drain plug, a damper and a fuel reflector are made in one piece with a cover, characterized in that the filter equipped with a damper installed on the bottom of the glass, a mesh filter element, which is located on the Central filter rod, inside the mesh filter element is a moisture-absorbing material, and mesh the filter element together with the moisture-absorbing material are made removable.

Description

The utility model relates to engine building, in particular to fuel filter sedimentation tanks.

Known fuel filter - sump, including a cover with holes for supplying and removing fuel, a glass, a central rod mounted on the cover, a mesh filter element, a reflector and a fuel damper [1].

Known fuel filter - sump has disadvantages, which include the following:

- low fuel filtration by the mesh element;

- leaching of settled mechanical impurities;

- difficulty in maintenance.

The purpose of the utility model is to create a simple in design, increase the quality of fuel cleaning, prevent leaching of settled mechanical impurities, easy to maintain and increase the life of the engine.

This goal is achieved by the fact that the filter is equipped with a damper. The damper is installed at the bottom of the glass. A mesh filter element located on the central filter rod. A moisture-absorbing material is disposed inside and the mesh filter element, the mesh filter element and the moisture-absorbing material being made removable.

Figure 1 shows a longitudinal section of a filter settler.

The filter settler includes a cover 1 with an opening for supplying fuel 2, with a central rod 3 having an opening for removing purified fuel 4, a glass 5 with a drain hole closed by a drain plug 6, a damper 7 and a fuel reflector 8 are made in one piece with the cover 1 , a damper 9 mounted on the bottom of the glass 5, a mesh filter element 10 located on the Central rod 5 of the filter, inside of which is a moisture-absorbing material 11, and the mesh filter element together with a moisture-absorbing material are made with emnymi.

The filter sump works as follows. Fuel enters the filter through the hole 2 for supplying fuel in the lid 1, while the ingress of the non-settled fuel to the filter element grid is protected by a reflector 8. Next, the fuel flows along the conical surface of the damper 7 through the gap between the inner wall of the glass and the outer edge of the damper. The conical surface of the damper provides a uniform distribution of fuel flow along the perimeter of the glass. Due to the loss of fuel flow rate, large particles of impurities settle on the bottom of the glass. The washing out of settled mechanical impurities is prevented by a damper 9 mounted on the bottom of the glass. Then the fuel passes to the mesh filter element 10, fixed on the Central rod 3. Next, the fuel enters the cavity where the moisture-absorbing material 11 is located inside the mesh filter element. Passing through the wallpaper filters, the fuel is cleaned of small mechanical impurities and water. Then the fuel through the hole in the rod 4 enters the fuel system. Sludge is drained through the hole in the glass by unscrewing the drain plug 6. To clean the filter element, it is made removable.

The presence of an additional moisture-absorbing material in the sump filter, which absorbs moisture from the fuel, thereby increasing the quality of the fuel. In addition, during maintenance, it is necessary to check the contamination of the mesh element and moisture-absorbing material, for convenience, they are made removable. The washing out of settled mechanical impurities is prevented by a fuel damper. The service life of the engine is increased due to high-quality cleaning of fuel from pollution.
