    摘要： The present invention discloses an air extractor, including a liquid cavity, an air extracting cavity, a connection channel, a drainage channel, and an air extracting channel, where the liquid cavity contains rotating liquid, the air extracting cavity has liquid therein, the liquid in the air extracting cavity is in communication with the liquid cavity through the connection channel, the liquid cavity drains the liquid through the drainage channel, the air extracting cavity is in communication with an object to be subjected to air extraction through the air extracting channel, and air in the object to be subjected to air extraction flows through the air extracting channel into the air extracting cavity. According to the air extractor provided in the present invention, the air is extracted by negative pressure generated by flowing of the rotating liquid, and the negative pressure can be increased by using a rotating fluid that is relatively denser. The air extractor provided in the present invention has small vibration and noise, and is easy to manufacture and has a small volume.

    摘要： A method of and apparatus for pumping fluids wherein a rotating ring of liquid traverses a hollow probe which has a surface aperture out of which the fluid to be pumped is sucked into the rotating liquid ring, wherein said fluid migrates to a collection region inside the rotating liquid ring, from whence the fluid can pass to a fluid outlet, and wherein a gas which does not condense under the prevailing operating conditions is also fed to the collection region in order to assist throughput of the fluid being pumped.
