Abstract
The utility model discloses an engine oil suction filter assembly. The engine oil suction filter assembly comprises an engine oil filter screen, an elastic retaining ring and a funnel-shaped suction filter shield, wherein an annular groove is formed at the large opening end of the suction filter shield and provided with an opening facing the center of the large opening of the suction filter shield, the edge of the engine oil filter screen and the elastic retaining ring are arranged in the annular groove of the suction filter shield, and the elastic retaining ring is positioned on the outer side of the engine oil filter screen. The engine oil filter screen is arranged in the annular groove of the suction filter shield through the elastic retaining ring, so that the engine oil filter screen is easy to replace, and the whole of the engine oil filter screen is easy to assemble. The engine oil suction filter assembly has the advantages of simple structure, reliability in working, easiness in maintenance, economy and practicability.
Description
Technical field
The utility model relates to a kind of oil strainer, particularly a kind of engine oil strainer assembly.
Background technique
Now, the sump strainer assembly great majority that adopt on the motor are by modes such as welding or flange punching presses oil filter screen and fuel filter cover to be installed together.The fuel filter assembly manufacture cost of this structure is higher, be unfavorable for changing.If oil filter screen stops up, the filter screen replacing that is difficult to dismantle needs to change whole fuel filter assembly, has strengthened user's maintenance expenses, and has wasted material.
Summary of the invention
Problem to be solved in the utility model is: a kind of engine oil strainer assembly of being convenient to change oil filter screen is provided.
In order to solve the problems of the technologies described above, the utility model comprises oil filter screen, circlip and funnel shaped fuel filter cover, the big opening end of fuel filter cover is provided with the circular groove of opening towards the Da Kou center of fuel filter cover, oil filter screen edge and circlip are arranged in the circular groove of fuel filter cover, and circlip is positioned at the outside of oil filter screen.
In order to guarantee fuel delivery, the mesh gross area is greater than the sectional area of the oil pump oil inlet pipe pore that is used for being connected with fuel filter cover small end on the described oil filter screen.
For the ease of the installation and removal of back-up ring, described circlip is a split washer.
The beneficial effects of the utility model are: oil filter screen of the present utility model is arranged in the circular groove of fuel filter cover by circlip, and oil filter screen is changed easily, and integral body is assembled easily, and the utility model is simple in structure, reliable operation, easy care, economical and practical.
Description of drawings
Fig. 1 is a complete section structural representation of the present utility model.
Fig. 2 is a user mode schematic representation of the present utility model.
Among the figure: 1, fuel filter cover, 2, circlip, 3, oil filter screen, 4, the oil pump oil inlet pipe.
Embodiment
As shown in Figure 1, the utility model comprises fuel filter cover 1, circlip 2 and oil filter screen 3.
As shown in Figure 2, the internal diameter of fuel filter cover 1 small end is bigger slightly than oil pump oil inlet pipe 4 external diameters so that oil pump oil inlet pipe 4 be inserted into the small end of fuel filter cover 1 after the joint can weld smoothly.During engine operation, the machine oil in the oil sump passes the filter opening in the oil filter screen 3, enters in the fuel filter cover 1, is filtered greater than the impurity of filter opening.If the filter opening on the oil filter screen 3 is blocked, cause flow resistance excessive, the engine oil supplying deficiency, engine oil pressure reduces.During maintenance service, the circlip in the fuel filter cover 2 can be taken out, change oil filter screen 3.
