Abstract

PURPOSE: To reduce the number of parts and make an entire orgeanization smaller by constituting a space volume formed by a rotor and stator of a motor so that the space volume may change as the rotor revolves and by allowing the motor to actuate pumping function.
CONSTITUTION: A rotor 3 made of a permanent maget is fitted to a shaft 1 through a pipe 4 and a bearing 5 so that it may rotate freely. A roller 6 is placed into a slit 8 provided on the periphery of the rotor 3, allowing a free volution. The shaft 1 and rotor 3 are installed to an inside yoke 9 so that they may be slightly deviated from each other. When the rotor 3 revolves in a pump chamber, the space volume formed by the rotor 3, the inside yoke 9 and the stator 7, changes and the pumping action is performed. This construction removes an indipendent rotor or a pumping unit, thereby reducing the number of parts.
