摘要： The invention concerns a device (12) for controlling an air flow (F) circulating in a first heat exchanger (4) for a motor vehicle comprising at least two screens (14), the control device (12) being configured to go from a closed configuration in which the screens (14) obstruct the passage of the air flow (F) completely to an open configuration in which the screens (14) are positioned in such a manner as to allow the air flow (F) to pass with a maximum flow rate, and any intermediate configuration. According to the invention, the two screens (14) are adapted to be moved away from one another when the control device (12) goes from the closed configuration to the open configuration and to be moved toward one another when the control device (12) goes from the open configuration to the closed configuration.

摘要： 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.
