Title (EN) STIRLING CYCLE MACHINE
(FR) APPAREIL A CYCLE DE STIRLING
Abstract:
(EN) A Stirling cycle machine has a piston (11) which reciprocates in a cylinder (12) and defines a hot chamber (23) between the piston (11) and end of cylinder (12). Heat exchange for the working fluid in the hot chamber (23) is effected while the working fluid is outside the hot chamber (23) in a flow path (24) communicating with that chamber (23). The piston (11) has a concave crown forming a surface (31) of the hot chamber (23). A seal is provided by a land (33) of larger diameter than the general diameter of the piston (11) formed around the upper periphery of the piston (11) and at least one annular groove (36) formed in the land (33) to disrupt free flow of working fluid along the gap between the land (33) and the cylinder wall.
(FR) On décrit un appareil à cycle de Stirling qui comprend un piston (11) alternatif placé dans un cylindre (12) et une chambre chaude (23) située entre le piston (11) et l'extrémité du cylindre (12). L'échange thermique pour le fluide de travail dans la chambre chaude (23) s'effectue pendant que le fluide de travail se trouve hors de la chambre (23) dans un circuit d'écoulement (24) communiquant avec cette dernière. Le piston (11) comporte une couronne concave formant une surface de la chambre chaude (23). Un joint d'étanchéité est constitué par un appui (33), de diamètre supérieur au diamètre général du piston (11), formé autour de la périphérie supérieure du piston (11); et au moins une rainure annulaire (36) est formée dans l'appui (33) pour empêcher un écoulement libre du fluide de travail le long du passage entre l'appui (33) et la paroi de cylindre.
