ROTOR ENGINE Russian patent published in 1997 - IPC

FIELD: engine engineering. SUBSTANCE: engine has housing with cylindrical bore, cylindrical stator ring coaxially mounted in bearings inside the housing, eccentrically mounted rotor with diametrical grooves, and plates received in the grooves to form working chambers inside the stator ring. The number of plates is even. The inner side of the stator ring is made up as a polyhedron coaxial with its outer side and provided with working sides the number of which is equal to the number of the separating plates. The opposite plates are rigidly interconnected through rods which pass through the rotor and abut against the working sides of the stator ring by their contact surfaces which are at a right angle to the surface of the plate and in width is lager than its thickness. EFFECT: enhanced reliability. 7 cl, 11 dwg
