Abstract
A combined type oil filter relates to oil filters. The invention aims at overcoming the defects existing as bypass valves are fixed with filter elements into a whole in the prior art. The combined type oil filter comprises a split type shell (1), a filter element (2), a filter element bracket (3) and a bypass valve (4), wherein the filter element, the filter element bracket and the bypass valve are arranged in the shell; the bypass valve (4) is arranged at the lower end of the cavity of the filter element bracket (3) and comprises a base (41), a valve sheet (42), a return spring (43) and an upper cover (44); the valve sheet (42) is arranged on a central hole (45) of the base (41); the upper cover (44) is connected with the base (41) in a dismountable manner; the return spring (43) is arranged between the upper cover (44) and the base (41) after being precompressed; and the upper cover (44) is provided with an oil passage. During fault maintenance, a bump (48) emerges from a stopper (46) only by rotating the bypass valve of the oil filter of the invention towards the opposite direction, thus the operation is convenient and labor-saving.
Description
Technical field
The present invention relates to a kind of oil filter.
Background technique
The effect of oil filter is that the machine oil that enters the motor main oil gallery is carried out filtering, makes machine oil reach certain turbidity test, prevents each moving element in the motor because impurity causes early stage abrasive wear.Proper functioning during for the effective working pressure that guarantees main oil gallery and cold starting then needs fitting machine oil rectifier bypass valve.The oil filter bypass valve is in parallel with filter cleaner in lubrication system.When the engine oil pressure through oil filter dropped to above bypass valve cracking pressure design load, bypass valve was opened, and part machine oil is just walked around filter cleaner and flowed to working connection by bypass valve.Guarantee that working connection has enough machine oil, avoids filter cleaner to be subjected to impacting with high pressure simultaneously.In the existing oil filter, bypass valve is the structure that is fixed as one with filter core, is non-disconnectable formula structure, when bypass valve breaks down, is not easy to maintenance, can only integral body scrap.
Summary of the invention
For solving in the prior art bypass valve and the filter core existing drawback that is solidified as a whole, the invention provides a kind of combined oil filter.
Technological scheme of the present invention is as follows: it comprises split type housing 1, is arranged on the filter core 2 of housing 1 inside, filter core support 3 and bypass valve 4, described bypass valve 4 is arranged on the lower end of filter core support 3 inner chambers, described bypass valve 4 comprises base 41, valve block 42, return spring 43 and loam cake 44, described valve block 42 is arranged on the center hole 45 of base 41, between loam cake 44 and the base 41 for removable be connected and 43 precompression of described return spring after be arranged between loam cake 44 and the base 41, have the passage that goes rancid on the described loam cake 44.
As improvement of the present invention, the lower surface of described loam cake 44 is fixed with the projection 48 of three uniform settings, and the upper surface of described base 41 is fixed with the block 46 of three uniform settings, and the sectional shape of described block 46 is
Shape, the projection 48 of described three uniform settings are inserted between the block 46 of three uniform settings and after the rotation and are installed on
Between the upper surface of the lower surface of shape block 46 and base 41.
As a further improvement on the present invention, the outer wall of described loam cake 44 is provided with the protruding circle 47 of ring-type, and the center hole wall of described filter core support 3 is provided with the projection 34 suitable with the protruding circle of ring-type 47.Be understandable that, also can be between loam cake 44 and the base 41 and be threaded.
Further improve as of the present invention, described filter core support 3 comprises that overhead gage 31, sidewall have the newel 32 and the lower pedal 33 of oil through, and described base 41 is fixed with one with the lower pedal 33 of filter core support 3.
The bypass valve of oil filter of the present invention when breakdown maintenance, only needs the opposite direction rotation, and projection 48 is promptly deviate from from block 46, and is easy to operate.

Fig. 1 is an overall structure schematic representation of the present invention;
Fig. 2 is bypass valve 4 of the present invention and filter core support 3 assembling schematic representation;
Fig. 3 is the A-A sectional view of Fig. 2.
Embodiment
Specify embodiment below in conjunction with Figure of description.
As shown in Figure 1, present embodiment is made up of split type housing 1, the filter core 2 that is arranged on housing 1 inside, filter core support 3 and bypass valve 4, described bypass valve 4 is arranged on the lower end of filter core support 3 inner chambers, described bypass valve 4 comprises base 41, valve block 42, return spring 43 and loam cake 44, described valve block 42 is arranged on the center hole 45 of base 41, between loam cake 44 and the base 41 for removable be connected and 43 precompression of described return spring after be arranged between loam cake 44 and the base 41, have the passage 49 that goes rancid on the described loam cake 44.In the using process, the spring force that pressure oil overcomes return spring 43 backs down valve block 42, and then by the passage that goes rancid on the loam cake 44, part machine oil is just walked around filter cleaner and flowed to working connection by bypass valve, can guarantee that working connection has enough machine oil, effectively avoids filter cleaner to be subjected to impacting with high pressure.
Preferably, the lower surface of described loam cake 44 is fixed with the projection 48 of three uniform settings, and the upper surface of described base 41 is fixed with the block 46 of three uniform settings, and the sectional shape of described block 46 is
Shape, the projection 48 of described three uniform settings are inserted between the block 46 of three uniform settings and after the rotation and are installed on
Between the upper surface of the lower surface of shape block 46 and base 41, when breakdown maintenance, only need the opposite direction rotation, projection 48 is promptly deviate from from block 46.
More preferably, the outer wall of described loam cake 44 is provided with the protruding circle 47 of ring-type, and the center hole wall of described filter core support 3 is provided with the projection 34 suitable with the protruding circle of ring-type 47.Be understandable that, also can be between loam cake 44 and the base 41 and be threaded.
