ROTARY MACHINE Russian patent published in 2001 - IPC

FIELD: mechanical engineering; compressors, pumps, internal combustion engines. SUBSTANCE: rotary machine has follow cylindrical housing with end face covers and synchronization mechanism in form of shaft with monolith cross. Housing accommodates blades with rollers which divide its space into four closed chambers. Shafts with rollers are fitted into blades through holes. Shafts with rollers are provided with eccentrics. Cylindrical surfaces are formed to shape in end face covers symmetrically in diametrically opposite directions with radius displaced from center of blade rotation in vertical in coordinate grid by eccentricity plus-minus value and radius displaced in horizontal symmetrically relative to center of rotation. Additional rollers are installed on ends of eccentric shafts. Diameters of these rollers are less than diameters of rollers in contact with profiled surface in end face covers in which segment projections are formed to shape in diametrically opposite directions from center of blade rotation by eccentricity minus value. EFFECT: elimination of unbalance. 2 dwg
