ABSTRACT:
The rotor housing of a rotary piston internal combustion engine comprises inner and outer walls between which coolant channels are defined. The channels are separated by webs and at least some of these webs, normally in the combustion areas, extend at an angle of 281/2.degree. to the radial direction to achieve a stress distribution which minimizes the risk of web root failure.
