US 7,118,353 B2 · Fluid transport system and method therefor

Abstract

A reduced pressure or pressurizing pump is provided which can be used in a wide variety of fields of foods, pharmaceuticals, medical treatment, agriculture, healthcare equipment, room air conditioning, combustion, biotechnology, and so on. By the application of the pump of the present invention, there can be materialized, for example, an oxygen enriching apparatus or a nitrogen enriching apparatus, which have the features of an oil-free structure, a small size, compactness, low vibration, low noise, long operating life, and so on. A transport groove of a viscosity pump, which exerts a force feed action on the fluid, is formed at a relative displacement interface between a rotor and a housing, and the rotor supported by a bearing capable of coping with a high-speed rotation is rotated at a high speed.

Dependent claims

A fluid transport system comprising:

a housing:
a rotor housed in said housing;
a fluid transfer chamber formed of said rotor and said housing;
fluid inlet and outlet ports that are formed at said housing, each of said fluid inlet and outlet ports for communicating with said fluid transfer chamber;
a bearing for supporting rotation of said rotor, said fluid transfer chamber and said fluid inlet and outlet ports;
and
a motor for rotatively driving said rotor,
wherein a transport groove for exerting a fluid pumping action on fluid is formed at a relative displacement interface between said rotor and said housing, and
wherein two transport grooves of different passages for transporting the fluid are formed at the relative displacement interface.
