Preferably, which further includes by-passing valve, and the by-passing valve is arranged on the top in outer barrel.
The operation principle of the utility model is：
The central tube of the utility model is suitable for the anti-rotatable filter filled and (is equipped with machine oil import during installation and machine oil goes out
Mouthful end cap downward), using the central tube rotatable filter engine shutdown in the state of, the inner cylinder of central tube with it is interior
Sealing area is formed between tank body below cylinder top, machine oil can be still stored in the sealing area, when engine opens again
When dynamic, machine oil can be full of tank body, rapid delivery engine lubrication point after filtering, so as to save in machine within the very short time
The space of oily clean side arrangement check-valves and cost.
Compared with prior art, the utility model has the advantages that：
(1) it is simple in structure, securely and reliably：Check-valves is installed in clean side relative to needs, center tube structure is simple, arrangement
Very convenient, reliable operation, there is no the problem of similar non-return defective valve.
(2) filter efficiency is high：Double-layered central pipe structure (inner and outer tubes) provide not only fluid and enter clean inner tube
Runner gap, and the utilization rate of filter core is more balanced, so as to help engine more energy-saving and emission-reduction.And in shutdown status
Under can store more machine oil, reduce the time that oil delivery is reached to after engine start each oil site；Outer barrel and inner cylinder
Between gap become larger from top to bottom, further increase the machine oil amount of storage under shutdown status.
(3) use scope is wide：Percent opening of the length of the inner tube of central tube, diameter and outer tube filtering window etc. can be according to not
Same filter core carries out seriation exploitation.
(4) production cost is low：The central tube is avoided installs check-valves in clean side, has saved production and assembly cost.
