Abstract
A Stirling cycle engine comprises a substantially sealed engine block that defines a working fluid space, a hot path and a cold path. A heat source and a heat sink are configured to keep the hot path and the cold path at different temperatures. The engine includes a valve chamber that is communication with the working fluid space, the hot path and the cold path. A valve is moveably positioned within the valve chamber between at least a first position and a second position. The valve defines a passage that, in the first position, places the working fluid space in communication with the hot path and, in the second position, places the working fluid space in communication with the cold path. A regenerator positioned within the passage.
