ROTOR-PISTON ENGINE HOUSING Russian patent published in 2008 - IPC F02B55/08 F02B55/10 

FIELD: engines and pumps.

SUBSTANCE: invention relates to motor industry, particularly to rotor-piston internal combustion engines (RPE). The casing of, at least, one-section RPE incorporates a stator, a rotor, a cam shaft, stator covers bolted- or pinned-together. Coupling bolts or pins pass through the stator inner loop to come as close to the rotor inner working surface as possible. In the hot zone with the inner wall-shell heating to the temperature of 240°C÷260°C, the distance to the center of coupling bolts or pins lies in the range S=1.2...1.5d, where d is a diameter of the said coupling bolt or pin. The stator is cooled by cooling liquid forced through narrow slot-like channels formed by holes in stator and coupling bolts or pins, the slot width making h=0.1...0.2d. In the said hot zone, nearby the spark plug, the said coupling bolts or pins with slot-like channels surrounding them are located in the stator inner loop close to each other. The cooling liquid channels are located in the stator central part, that is, in the said hot zone. The channels feeding cooling liquid to the stator covers make a continuation of those feeding the stator cooling liquid. The stator is furnished also with channels to feed air or fuel-air mixes passing through the stator hot zone into the RPE intake.

EFFECT: decreased bending moment deforming the stator inner wall-shell and the stator covers.
