摘要:
The transfer - expansion - regeneration combustion engine (1) comprises a compressor (2) which delivers gases into a high-pressure regeneration pipe (6) of a regeneration heat exchanger (5) from which pipe the gases emerge preheated via a regenerator high-pressure outlet pipe (9) which comprises a heat source (12) which superheats said gases, the latter then being transferred by an intake metering valve (24) operated by a metering valve actuator (25) to a transfer - expansion chamber (16) notably formed by an expansion cylinder (13) and an expansion piston (15), said gases re-emerging from said chamber (16) having been expanded via an expanded-gases exhaust pipe (26) and via an exhaust valve (31) operated by an exhaust-valve actuator (32) before being cooled in a regeneration low-pressure pipe (7) that the regeneration heat exchanger (5) comprises.

摘要:
A compressed-air energy storage system according to embodiments of the present invention comprises a reversible mechanism to compress and expand air, one or more compressed air storage tanks, a control system, one or more heat exchangers, and, in certain embodiments of the invention, a motor-generator. The reversible air compressor-expander uses mechanical power to compress air (when it is acting as a compressor) and converts the energy stored in compressed air to mechanical power (when it is acting as an expander). In certain embodiments, the compressor-expander comprises one or more stages, each stage consisting of pressure vessel (the “pressure cell”) partially filled with water or other liquid. In some embodiments, the pressure vessel communicates with one or more cylinder devices to exchange air and liquid with the cylinder chamber(s) thereof. Suitable valving allows air to enter and leave the pressure cell and cylinder device, if present, under electronic control.
摘要:
An auxiliary power system for providing electrical power and heat to an indoor area includes an external combustion engine, such as a Stirling cycle engine (101), for generating mechanical energy and thermal energy. The external combustion engine (101) burns a fuel with substantially complete combustion such that exhaust emissions from the external combustion engine (101) are below a predetermined exhaust level. A generator (102) is coupled to the external combustion engine (101) and converts the mechanical energy produced by the external combustion engine (101) to electrical power. A first power output is used to provide the electrical power produced by the generator (102). The external combustion engine (101) and generator (102) are disposed within a housing such that the external combustion engine (101), generator (102) and housing combination is a portable size. The thermal energy generated by the external combustion engine (101) may be used to heat the atmosphere surrounding the housing.
摘要:
Un moteur rotatif comprend un carter (10) possédant une surface interne cylindrique pourvue de joints empêchant l'écoulement des gaz des espaces entre deux pistons rotatifs sur des axes séparés mais concentriques. Trois groupes d'engrenages (27, 28, 29) commandent la rotation relative des pistons qui s'écartent et se rapprochent pour comprimer les gaz entre les pistons. Un arbre d'entraînement (33) est relié par le premier groupe d'engrenages (27) au premier axe concentrique (18). L'arbre d'entraînement est également relié par un deuxième groupe d'engrenages (28) à l'autre arbre concentrique (16). Le troisième groupe d'engrenages (29), comprenant des engrenages non circulaires, relie l'arbre d'entraînement à un arbre de sortie (38).
摘要:
The present invention refers to the technical field of thermodynamic engines, and more specifically to a heat engine that operates with gas in closed loop in differential configuration which is characterized by performing a thermodynamic cycle eight transformations or otherwise explain, it performs two thermodynamic cycles simultaneously, each with four interdependent, additional transformations, two of these transformations "isothermal" and two "adiabatic" in mass transfer in phases of adiabatic processing to provide a new performance curve no longer dependent solely on temperature but the mass transfer rate which allows the construction of machines with high yields and low thermal differentials.
