The utility model is set to further: described filter member comprises support filter cylinder, and described support filter cylinder is provided with filter paper, and one end of described support filter cylinder is connected with oil outlet tube.

By adopt technique scheme, by support filter cylinder filter paper is supported, and by support filter cylinder sheathed live filter paper, by the contact with machine oil maximum area, make filtering effect better.

The utility model is set to further: described shell is removably connected with bottom, and described bottom is provided with the restraining groove closed with filter paper matching form.

By adopting technique scheme, by dismountable bottom, the replacing of filter member can be realized, and bottom is provided with the restraining groove suitable with filter paper shape, make the shape of the good spacing filter paper of restraining groove energy, make filter paper still can keep original shape under the environment washed away of machine oil, avoid mutually binding reducing filtering effect.

The utility model is set to further: described inner chamber carrying magnetic.

By adopting technique scheme, after machine oil flows into inner chamber, the iron filings be mixed in machine oil can not be filtered part to adsorbing, and can also by inner chamber to holding, while inner chamber holds iron filings, also reduce the quantity of iron filings in filter member, thus add the working life of filter member.

Compared with prior art, the utility model has the advantage of: effectively solve oil filter of the prior art when bypass valve is connected, bring the iron filings secondary sticked on filter paper into machine and machine caused to the problem of damage.
