The present invention provides a fluid transferring device for pumping or compressing a fluid to be transferred. The fluid transferring device comprises: an outer rotor; an inner rotor; a suction opening; a discharge opening; a first plate; and a second plate. The outer rotor has an interior with a cylindrical shape and an inner space allowing the fluid to be introduced thereinto and has at least three compression areas having an equal shape and formed on the inner space at equal intervals. The inner rotor has at least one compression wing. The compression wing is rotated about a central axis, arranged on the inner space of the outer rotor that is inserted into the compression areas, has sealing reference surfaces formed on both lateral sides to seal the compression area, and has an outer circumferential surface in contact with inner circumferential surfaces of the compression areas. The suction opening introduces the fluid from the outer rotor into the interior thereof. The discharge opening discharges the fluid in the compression areas to the outside. The first plate seals one side surface of the fluid transferring device from the outside. The second plate seals the other side surface of the fluid transferring device from the outside. |
