Abstract
An apparatus () has a compressor (), heat rejection heat exchanger (), heat absorption heat exchanger (), and expansion-compression device (). The expansion-compression device couples the heat absorption heat exchanger to the heat rejection heat exchanger and to the compressor. The expansion-compression device comprises first (A), second (B), third (C), and fourth (D) variable volume chambers and a pivoting member. The pivoting member () is mounted for reciprocal rotation in opposite first and second directions about an initial orientation and is coupled to the chambers so that: rotation from the initial orientation in the first direction expands the first and third chambers and compresses the second and fourth chambers; and rotation from the initial orientation in the first second direction compresses the second and third chambers and expands the second and fourth chambers.
