Abstract:
1. An air compressor comprising: a frame, said frame formed in a generally circular circumference formed of a plurality of individual linear members, each linear member having two ends and center portions between said ends; means for rotational support of said frame above a surface; means for rotational angled engagement of said ends of said linear members forming said frame, to adjacent said ends of said linear members; a planar circular member located at said center portions of each of said linear members; each planar circular member having two sides defining two opposing side surfaces; adjacent said planar circular members engaged to adjacent said linear members thereby forming a plurality of pairs of planar circular members with facing respective said side surfaces; said angled rotational engagement of said linear members placing said facing side surfaces of each of said pair of said pair of circular planar members at an angle to the other of said pair; a pathway formed between said respective side surfaces of each said pair of planar circular members, said pathway being wider outside said circumscribed area of said frame, and narrowest inside said circumscribed area of said frame; a plurality of collapsible members, engaged to said side surfaces adjacent to said member circumference and between each said pair of planar circular members; said collapsible members having an internal cavity communicating with an intake aperture and a discharge aperture; means for powered rotation of said planar circular and said linear members forming said frame for imparting a rotation of said linear members and said circular members toward said inside of said circumference; said collapsible members engaged between said each said pair of planar circular members alternating between an enlarged dimension outside said frame circumscribed area, to a collapsed dimension inside said frame circumscribed area, during said rotation; a first time duration during said rotation causing a translation of said collapsible members from said enlarged dimension to said collapsed dimension; a second time duration during said rotation causing a second translation of said collapsible members from said collapsed dimension to said enlarged dimension; means to communicate gas discharged from each said internal cavity, to a common reservoir, only during a portion of said first time duration; means to communicate gas from the atmosphere into said internal cavity only during a portion of said second time duration; whereby said gas from said plurality of collapsible members between each said pair of planar members, is communicated to said common reservoir for storage in a pressurized state.
