Document Type and Number:
WIPO Patent Application WO/2019/169572
Kind Code:
A1
Abstract:
Disclosed is a cleanable engine oil filter assembly, comprising a paper filter (2), a magnetic oil purification valve (4) and an open-close component. The filter has a hollow cavity and is provided with an oil inlet hole (102); the paper filter (2) is arranged outside the hollow cavity; the oil inlet hole (102), the paper filter (2) and the hollow cavity constitute a flow channel I; the open-close component is arranged inside the filter; when the open-close component is opened and the flow channel I is closed, the oil inlet hole (102), the open-close component and the hollow cavity constitute a flow channel II; and the magnetic oil purification valve (4) is embedded in the filter and is selectively in communication with the hollow cavity. By means of the structure, only the paper filter needs to be replaced, and thus, the cleanable engine oil filter assembly is simple to operate and saves on costs.
