When the flow rate on the filter element 8 decreases, under the action of pressure, a pair of springs 15 of the flow blocking block 14 will be compressed, thus leaking out gaps to allow the oil fluid to flow through and prevent the filter element 8 from being damaged.

[0038] Thus, a series of operations are completed. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.
