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 oil filter with oil level control, which belongs to the technical field of automobile engine air filters. The device of the invention includes a casing, and the port of the casing is covered by a threaded cover plate. The oil inlet for inputting the fluid, and the oil outlet for discharging the filtered fluid in the housing, the filter element assembly is set in the housing for filtering the fluid entering the oil inlet and discharging the filtered oil from the oil outlet, the filter element The upper end of the component is equipped with a filter element cover plate, which has a second oil inlet pipe for discharging the filtered fluid, and a concave annular assembly ring groove is provided between the outer wall of the second oil inlet pipe and the filter element cover plate, and the threaded cover plate has a Assembling the first oil inlet pipe with the ring groove plugged in, the first oil inlet pipe and the second oil inlet pipe form the oil outlet, the invention effectively eliminates the air in the oil circuit, and realizes the connection reliability between the filter element assembly and the threaded cover plate , to solve the problem of air entering the oil circuit due to loose parts.

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...
