Abstract
A rotary machine, such as a rotary engine, a rotary pump and the like, has a plurality of rotors which are so arranged and shaped that they roll over one another and together bound a permanently closed during rotation, working chamber. This working chamber is closed peripherally by the rotors, and axially by covers. The shape of the rotors may be formed by an inner envelope of a square which is connected with an inner larger circle rolling over a smaller circle. The shape of the rotors may also be produced by an inner envelope of a triangle whose inner larger circle rolls over a smaller circle.
