FIELD: engine and pumps.
SUBSTANCE: invention relates to blade pump. Proposed pump comprises housing 2 with pumping chamber 2A wherein annular inner wall is made, rotor 3 revolving off-centered relative to the center of pimping chamber 2A and sliding in contact with inner wall of the said chamber to continuously divide is into multiple subchambers. Housing 2 has inlet channel 6 and outlet channel 7. Rotor 3 and housing 2 have oil feed channel communicating periodically with pumping chamber 2A when rotor 3 revolves. Lubricating oil is periodically fed through hole of chamber 2A arranged on the side of outlet channel 5. Oil feed channel and pumping chamber 2A can intercommunicate.
EFFECT: blade operating with minor amount of lubricating oil.
