Abstract

L'invention concerne une machine à piston comprenant un mécanisme sans bielles, laquelle comprend un corps (1) avec des cylindres (2), des pistons (3) qui sont connectés rigidement entre eux par paires par des tiges (4) couplées via des paliers (5) par les goujons (6, 7) d'un vilebrequin tournant de façon planétaire, lequel se trouve dans un corps (1) et comprend deux manivelles doubles (8, 9) connectées par charnière et disposées dans des ouvertures excentriques (10) de coussinets (11) comportant des couronnes (12), et un arbre de sortie de puissance (13) avec un dispositif de synchronisation de son mouvement qui se compose de deux parties comportant chacune des pignons (14) qui s'engrènent entre eux et les couronnes (12) des coussinets (11). Cette invention permet de faciliter l'assemblage et l'équilibrage des pièces en mouvement tout en réduisant le poids et les dimensions hors-tout de la machine. Il est également possible de diminuer la puissance spécifique que l'on peut obtenir de l'0arbre de sortie de puissance.
