Embodiment 1

[0031] see Figure 1-8 As shown, a diesel filter with oil level control, including:

[0032] The housing 20, the port of the housing 20 is covered by the threaded cover plate 10, the threaded cover plate 10 has an oil inlet 11 for inputting fluid in the housing 20, and an oil outlet 12 for discharging the filtered fluid in the housing 20 ,

[0033] The filter element assembly 30 is set in the housing 20 for filtering the fluid entering the oil inlet 11 and discharging the filtered oil from the oil outlet 12,

[0034] Wherein, the upper end of the filter element assembly 30 is equipped with a filter element cover plate 70, the filter element cover plate 70 has a second oil inlet pipe 72 for discharging the filtered fluid, and a concave ring is provided between the outer wall of the second oil inlet pipe 72 and the filter element cover plate 70. Assembling the ring groove 71, the threaded cover plate 10 has a first oil inlet pipe 14 that is plugged and fitted with the assembly r...

Embodiment 2

[0046] The difference between this embodiment and Embodiment 1 is that a liquid level sensor is added in the filter element assembly 30 of this embodiment, which is not shown in the figure. The area between the highest level of the area is used to detect whether the oil body inside the filter element assembly 30 reaches the altitude layer. When it reaches the level, the trigger signal controls the air extraction assembly 40 to work and pumps part of the oil body into the oil tank to control the oil inside the filter element assembly 30. The oil outlet 12 is generally connected to a high-pressure oil pump to extract and filter the oil, and the oil inlet 11 is generally connected to an oil delivery pump to input diesel oil.

Embodiment 3

[0048] When the diesel oil filter with oil level control of the present invention actually works: the diesel oil is input into the housing 20 through the oil inlet through the oil transfer pump, the oil body continuously enters and precipitates in the housing 20, and impurities are deposited in the housing At the bottom of the body 20, when the oil body in the housing 20 reaches the level of the filter element assembly 30, the filter element assembly 30 filters the oil body so that it enters the interior of the filter element assembly 30 and is filtered by the secondary filter plate 60. During the above filtering process, the oil body The air present in the air will be separated and gathered on the top surface of the filter element assembly 30, and then discharged by the air extraction assembly 40. At the same time, the liquid level of the oil body in the housing 20 and the filter element assembly 30 can be controlled through the extraction assembly 40. When cleaning the filter...

Abstract

The invention discloses a diesel filter with an oil level control function, and belongs to the technical field of an air filter of an automobile engine. The diesel filter comprises a casing and a filter core assembly, wherein casing port is covered with a thread cover plate, and the thread cover plate is provided with an oil inlet allowing fluid to be input into the casing and an oil outlet used for discharging the filtered fluid in the casing; the filter core assembly is arranged in the casing and used for filtering the fluid entering from the oil inlet and discharging the filtered fluid fromthe oil outlet, a filter core cover plate is assembled at the upper end of the filter core assembly and is provided with a second oil inlet pipe used for discharging the filtered fluid, an indent annular assembly ring groove is formed between the outer wall of the second oil inlet pipe and the filter core cover plate, the thread cover plate is provided with a first oil inlet pipe in inserted matching with the assembly ring groove, and the first oil inlet pipe and the second oil inlet pipe constitute the oil outlet. According to the diesel filter with the oil level control function, air in theoil way is effectively removed, connecting reliability between the filter core assembly and the thread cover plate is realized, and the problem that air enters the oil way due to loosening of parts is solved.

Description

technical field [0001] The invention belongs to the technical field of automobile engine filters, in particular to a diesel oil filter with oil level control. Background technique [0002] During the working process of the automobile engine, the function of the diesel filter is to filter out the moisture and impurities in the diesel. Some existing filters include a shell, a threaded cover plate, a filter element assembly, and a water discharge valve. A cavity is provided between the shell and the filter element assembly. There are oil inlet and outlet ports on the plate, and the oil enters the cavity from the oil inlet, and flows out from the oil outlet after being filtered by the filter element assembly. [0003] However, for the filter of this structure, since the threaded cover plate and the filter element assembly are connected by glue, when the road condition of the car is very poor, a large vibration will be generated, thereby making the glued connection loose, and it...
