Abstract
The heat engine with transfer-expansion and regeneration (1) includes a compressor (2) which compresses gases in a high-pressure regeneration line (6) of a regeneration heat exchanger (5) from which they emerge preheated via a high-pressure regenerator outlet line (9) which has a heat source (12) that superheats the gases, the latter being then transferred by an admission metering valve (24) operated by a metering valve actuator (25) into a transfer-expansion chamber (16) formed in particular by an expansion cylinder (13) and an expansion piston (15), the gases leaving the chamber (16) after having been expanded via an expanded gas exhaust line (26) and thanks to an exhaust valve (31) operated by an exhaust valve actuator (32) before being cooled down in a low-pressure regeneration line (7) of the regeneration heat exchanger (5).
