ROTARY MACHINE Russian patent published in 2001 - IPC

FIELD: mechanical engineering; compressors, pumps and integral combustion engines. SUBSTANCE: rotary machine has cylindrical housing accommodating two blades with shafts and rollers dividing housing space into four closed spaces, and synchronizing mechanism in form of shaft with solid cross installed eccentrically to axis of rotation of blades. Fastening of shafts with rollers in engagement with cross is provided by fitting the shafts on two supports in detachable blades consisting of set of shaped inserts, cover plates and disks provided with holes and segment cutouts. Spring-loaded shafts with rollers on end are fitted in blades through holes. Disk in middle part of shaft is made integral with shafts. Cylindrical surface of disk is shaped to hexahedron. Parallel flats engaging with plane surface of elongated holes in blades cut in radial direction are made on shafts from both sides of device. Segment cutouts are provided in blades for symmetrical outlet of shaft extensions. EFFECT: reduced specific loads, eliminated wedging of mechanism. 3 dwg
