Embodiment Construction

[0022] The present invention discloses a low cost, easy to manufacture rotary or spin pump assembly for use in oxygen concentrators. In one embodiment, the spin pump assembly operates as a compressor pump on a PSA cycle. In another embodiment, the spin pump assembly operates as a vacuum pump according to the VPSA cycle. In an alternative embodiment, the spin pump assembly is a combination of a compressor pump (PSA) and a vacuum pump (VPSA). Said ease of processing is due to the fact that only the parts of the pump need have planar or cylindrical surfaces. In one embodiment, the pump component includes a working component surface comprising a portion of the pump component defining a piston or fluid chamber, or a portion adjoining an adjacent portion in fixed or movable relationship. Some non-limiting examples of working component surfaces include the inner wall of the piston chamber, and the spinning outer surface of the rotor adjacent the housing and bearing surfaces. Said ...

Description

[0001] References to Priority Documents [0002] This application claims priority to co-pending US Provisional Application 61 / 888,893, filed October 9, 2014, entitled "Spin Pump Having Spin Planetary Geometry." This application claims priority on the above filing date and this provisional application is hereby incorporated by reference in its entirety. Background technique [0003] There is a need for an inexpensive, compact, high-efficiency oxygen concentrator consisting of a compressor and a vacuum pump to drive a pressure swing and / or vacuum / pressure swing adsorption cycle that separates oxygen from ambient air, for example for the treatment of chronic obstructive pulmonary disease (COPD) Patients undergo treatment. Typically, such oxygen concentrators are available as stationary, transportable and portable. Patients who are still ambulatory generally prefer smaller transportable and portable units. These smaller devices have the most stringent requirements for compactne...
