Abstract
A compression and expansion machine is disclosed that includes a body with at least one chamber about an axis of symmetry, and pistons rotating about the axis of symmetry and dividing the chamber into cells rotating with the pistons. The invention also includes a device for coordinating the movement of the pistons and configured so that, during one rotation cycle, each of the cells performs at least one first expansion/contraction cycle corresponding to a stage of compressing a first stream of gas passing through this cell and at least one second expansion/contraction cycle corresponding to a stage of expanding a second stream of gas passing through this cell.
