ABSTRACT:
A rotary piston machine includes a housing provided with a cylindrical inner wall and at least one piston disposed inside the housing and rotating around a longitudinal central axis of the housing while moving back and forth in a linear manner, under the control of a control mechanism, to periodically enlarge and reduce the size of at least one chamber associated with the piston. The at least one piston moves linearly parallel to the longitudinal central axis of the housing.
