ROTOR INTERNAL COMBUSTION ENGINE Russian patent published in 1995 - IPC

FIELD: engine engineering. SUBSTANCE: engine has housing provided with the cylindric space, at least two rotatable blades being mounted at the space to define chambers of varying volume, side disks, working shafts, output shaft, and mechanism for converting motion which has two pairs of elliptic gears. One of the gears of each pair is mounted on the output shaft. The other one is coupled with the blades each of which is fixed to one of the working shafts and one of the side disks. The engine is provided with a bushing, the space of the bushing being provided with coaxial working shafts. Each of the blades is fixed to the opposite working shaft and side disk, The elliptic gears coupled with the blades are set in bearings inside the hosing and secured to the side disks, the side surface of which is mated with face surface of the bushing and mounted concentrically to the working shafts. The engine also has liquid cooling system which includes cooling spaces in the blades and supplying and discharging passageways. The supplying and discharging passages of each blade are axially alined and their outlets are arranged at the opposite sides of the working shafts. EFFECT: improved design. 2 cl, 4 dwg
