Embodiment 2

[0022] Such as Figure 5 As shown, the difference from Embodiment 1 is that the inner wall of the oil outlet pipe 11 of the housing is provided with a circle of stepped surface 114, and the boss 211 of the filter element end cover is sleeved in the oil outlet pipe 11 of the housing and then abuts against the stepped surface 114. The diameter of the part of the oil outlet pipe 11 located above the stepped surface 114 is equal to the inner diameter of the through hole 212 . After adopting this structure, since the diameter of the casing oil outlet pipe 11 located above the step surface 114 is equal to the inner diameter of the through hole 212, there is no resistance and no vortex when the fuel flows through the joint of the two, and the flow effect is good , High fuel filtration efficiency.

Abstract

The invention provides a diesel filter which comprises a shell and a filtering core arranged in the shell. The filtering core comprises a filtering core end cap and filtering paper arranged at the bottom of the filtering core end cap, a filtering core end cap boss is arranged on the top surface of the filtering core end cap and provided with a through hole communicating the inside with the outside of the filtering core, a shell oil outgoing pipe communicating the inside with the outside of the shell is arranged on the shell, one end, positioned in the shell, of the shell oil outgoing pipe is connected with the filtering core end cap in a sleeved manner, the filtering core end cap boss is arranged in the shell oil outgoing pipe in a sleeved manner, and protrusions around the filtering core end cap boss are arranged on the outer wall face of the filtering core end cap boss. The filtering core end cap boss is embedded in the shell oil outgoing pipe, and flowing resistance of fuel oil in the process of filtering of the filtering core can be eliminated, so that filtering efficiency of the fuel oil is improved.

Description

technical field [0001] The invention relates to a diesel oil filter. Background technique [0002] At present, the assembly structure of the filter element and the housing of most diesel filters in the industry is: the boss of the filter element end cover and the oil outlet pipe of the housing are an outer assembly structure, that is, the boss of the filter element end cover is sleeved outside the oil outlet pipe of the housing. The disadvantage of this structure is that the fuel oil will be hindered by the end face of the oil outlet pipe of the casing during the flow process of the filter element, thereby affecting the fluidity of the fuel oil to a certain extent. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a diesel oil filter. The boss of the filter element end cover is embedded in the oil outlet pipe of the casing, which can eliminate the flow resistance of the fuel during the filtering process of the filt...
