Eccentric mounting rotor rotating in the pump inside, which form centrifugal force driving vanes close to pump wall rotating, vanes divide pump body and rotor into multiple working chamber, when working chamber connect to inlet passageway, start to suction gas, vanes keep rotating and compressed gas into oil tank, oil tank inner constant differential pressure make oil enter compressed chamber, lubricated oil and extracted gas enter into oil tank, with gravity action, exhaust filter separate lubricated oil, lubricated oil back to the bottom of oil tank and enter into working chamber(oil recyle), oilless gas exhaust to atmosphere.
