A fluid withdrawing, expelling and filtering apparatus includes a fluid container including a first chamber, a second chamber, and, a first through hole and a second through hole respectively disposed in communication between the first chamber and the second chamber, a filter device movable between a first position and a second position to open or close the second through hole of the fluid container and including a filter element mating with the first through hole, and a fluid withdrawing and expelling operator operable to withdraw and expel a fluid through the first chamber of the fluid container.

First claim

Opening claim text (preview).

What is claimed is: 1. A fluid withdrawing, expelling and filtering apparatus, comprising: a fluid container comprising a first chamber, a second chamber, and, a first through hole and a second through hole respectively disposed in communication between said first chamber and said second chamber; a filter device movably disposed between a first position where said filter device opens said second through hole of said fluid container and a second position where said filter device closes said second through hole of said fluid container, said filter device comprising a filter element facing toward said first through hole; and a fluid withdrawing and expelling operator withdrawing and expelling a fluid through said first chamber of said fluid container, wherein said first through hole is disposed relatively closer to said fluid withdrawing and expelling operator than said second through hole, wherein said first through hole is located in the center of said fluid container, wherein said second through hole is located in the periphery of said fluid container, wherein said fluid container comprises a receptacle; said first through hole and said second through hole are located in said receptacle, wherein a first stop portion is located in said receptacle of said fluid container, wherein the receptacle is provided with a slidably-fitting inner periphery and the filter device is provided with a slidably-fitting outer periphery slidably fitted with the slidably-fitting inner periphery of the receptacle. 2. The fluid withdrawing, expelling and filtering apparatus as claimed in claim 1 , wherein said fluid container comprises a front cap, and a second stop portion located in said front cap. 3. The fluid withdrawing, expelling and filtering apparatus as claimed in claim 1 , wherein said fluid container comprises a barrel, and said receptacle mounted in said barrel. 4. The fluid withdrawing, expelling and filtering apparatus as claimed in claim 1 , wherein said fluid container comprises a barrel, and a front cap mounted in said barrel.
