ROTARY MACHINE Russian patent published in 1998 - IPC

FIELD: mechanical engineering; compressors, pumps and internal combustion engines. SUBSTANCE: rotary machine has hollow cylindrical housing divided by two blades 2,3 with shafts and rollers into four closed spaces. Housing is provided with end face covers. Synchronizing mechanism in form of shaft with solid cross is installed eccentrically relative to axis of rotation of blades 2,3. Bending torque at cantilever mounted shafts engaging with coupling mechanism cross 13 is eliminated by fitting the shafts on two supports by changing design of blades 2,3. Blades are made detachable, consisting of set of shaped inserts, cover plates and disks with holes and segment cutouts. EFFECT: enlarged operating capabilities; reduced bending loads. 4 dwg
