Title (EN) IMPROVEMENT IN FREE PISTON STIRLING ENGINES
(FR) AMELIORATION DES MOTEURS STIRLING A PISTONS LIBRES
Abstract: front page image
(EN)The present invention relates to improvements in free piston Stirling engines and more particularly to a spring mounting system for the displace piston (12) of such an engine. A Stirling engine having a cylinder block (10) defining a cylinder (11) a displacer piston (12) located in said cylinder (11) having a heated end and a cooled end, and at least one spring mounting means provided to mount and centre the displacer piston (12) in the cylinder such that the displacer piston (12) is free to oscillate in the cylinder in response to a pressure differential across the displacer piston (12), or other perturbing force, the spring mounting means (17) being located at the cooled end of the cylinder (11) between the cylinder (11) and the piston (12) comprise at least two spring members arranged.
(FR)L'invention concerne des améliorations apportées aux moteurs Stirling à pistons libres et, plus précisément, à un système de fixation de ressort du piston de déplacement (12) d'un tel moteur. Un moteur Stirling est pourvu d'un bloc-cylindres (10) définissant un cylindre (11), un piston de déplacement (12) placé sur ledit cylindre (11) ayant une extrémité chauffée et une extrémité refroidie et au moins un moyen de fixation de ressort conçu pour monter et centrer le piston de déplacement (12) dans le cylindre, ledit piston de déplacement (12) oscillant alors librement dans le cylindre en réponse à une différence de pression traversant le piston de déplacement (12), ou autre force perturbatrice; le moyen de fixation de ressort (17), situé à l'extrémité refroidie du cylindre (11), entre le cylindre (11) et le piston (12), comporte au moins deux éléments de ressort agencés.
