Description

Technical Field

[0001] The utility model relates to the technical field of filters, and more particularly to a filter which controls exhaust and oil supply functions through a valve. Background Art

[0002] A filter is a component that filters impurities or gases through filter paper. It generally refers to a diesel filter, which is an engine component.

[0003] Based on the above, the inventors found that the existing filter mainly functions as filtering, while also having water filtration and degassing functions, while the equipped electric pump has a relatively single function and can only be used for degassing or oil supply. In this case, the utilization of the electric pump will cause some waste. Therefore, in view of this, the existing structure is studied and improved to provide a filter that controls the exhaust and oil supply functions through a valve, in order to achieve a more practical purpose.

[0052] See Figure 6 One end of the exhaust quick connector 10 is installed in the exhaust channel 8 and is connected to the exhaust channel 8.

[0053] See Figure 6 and Figure 7 The other end of the regulating channel 12 has a through-oil supply hole 18, a through-exhaust hole 20 and a rotary valve outlet, which can selectively connect the exhaust channel 8 and the oil supply branch channel 9.

[0054] See Figure 6 An oil supply channel 15 is provided in the filter seat 1 , and the oil supply channel 15 is connected to the main oil supply one-way valve 4 .

[0055] See Figure 1 and Figure 6 The oil supply channel 15 is connected to the oil supply branch channel 9.

[0056] See Figure 1 and Figure 5 An oil inlet channel 16 is provided in the filter seat 1 , and the oil inlet channel 16 is connected to the interior of the filter cup 2 .

[0057] See Figure 5 and Figure 6The filter seat 1 is equipped with a filter screen 17, and the filter screen 17 is located at one end of the cavity 6 and is connected to the outside of the filter element through the external exhaust inlet 22 of the filter element.

[0058] Working principle:

[0059] Filter oil supply: The fuel enters the filter cup 2 through the oil inlet channel 16 on the filter seat 1, and after being filtered by the filter element, it passes through the oil extraction pipe 14 and enters the main oil supply check valve 4, and then enters the engine through the oil supply channel 15;

[0060] The multifunctional electric pump 3 has an exhaust function: the mixed oil and gas outside the filter element passes through the filter screen 17 and enters the cavity 1 6 through the exhaust inlet 22 outside the filter element. The mixed oil and gas inside the filter element enters the cavity 1 6 through the exhaust channel 21 inside the filter element through the gap between the oil extraction pipe 14 and the large central screw 13. Then, the mixed oil and gas are pumped into the cavity 2 7 through the multifunctional electric pump 3. At this time, the rotary switch 11 is rotated to connect the rotary valve outlet 19 in the regulating channel 12 with the exhaust channel 8. The mixed oil and gas then enter the exhaust channel 8 and are discharged back to the oil tank through the exhaust quick plug 10.

[0061] Multifunctional electric pump 3 oil supply function: Figure 8 As shown, the mixed oil and gas outside the filter element passes through the filter screen 17 and enters the cavity 1 6 through the exhaust inlet 22 outside the filter element. The mixed oil and gas inside the filter element uses the gap between the oil extraction pipe 14 and the central large screw 13 to pass through the exhaust channel 21 inside the filter element, and then through the multi-functional electric pump 3 to pump both into the cavity 2 7. At this time, the rotary switch 11 is rotated so that the rotary valve outlet 19 in the adjustment channel 12 is connected to the oil supply channel 15, and the fuel enters the oil supply channel 15 through the oil supply branch channel 9 and then enters the engine.

[0062] Multifunctional electric pump 3 mixing functions: Figure 7 As shown, the mixed oil and gas outside the filter element passes through the filter screen 17 and the exhaust inlet 22 outside the filter element into the cavity 1 6. The mixed oil and gas inside the filter element uses the gap between the oil extraction pipe 14 and the central large screw 13 to pass through the exhaust channel 21 inside the filter element, and then through the multi-functional electric pump 3 to pump both into the cavity 2 7. At this time, the rotary switch 11 is rotated to make the through-oil supply hole 18 in the adjustment channel 12 connected to the oil supply channel 15, and the through-exhaust hole 20 is connected to the exhaust channel 8. The fuel enters the oil supply channel 15 through the oil supply branch channel 9 and then enters the engine. The mixed oil and gas then enters the exhaust channel 8 and is discharged back to the fuel tank by the exhaust quick plug 10.
