Abstract (en)
[origin: WO7900157A1] In a rotary pistons machine comprising a cylindrical case and a coaxial driving shaft, the case (5, 18, 19, 20, 21) is provided with a rotary, chamber in which are placed three rotary pistons (15, 16, 17) having a sector shape and provided with seal joints. These pistons are juxtaposed and have angular speeds with periodical variation so that working volumes of which the size changes periodically are formed between the rotary pistons. For this purpose, the driving shaft (1) comprises an eccentric cam (1a) which bears a rotary driving disc (3) with internal toothing (3a). This internal toothing (3a) meshes with a toothed wheel (4). The rotary disc (3) bears driving pins (8, 11, 14) which are each in operating conjunction with a lever (7, 10, 13) and which are each rigidly connected to a rotary piston (15, 16, 17) through a hollow shaft (6, 9, 12).
Abstract (fr)
Dans une machine a pistons rotatifs comprenant un carter cylindrique et un arbre d'entrainement coaxial, le carter (5, 18, 19, 20, 21) est muni d'une chambre de rotation, dans laquelle sont disposes trois pistons rotatifs (15, 16, 17) en forme de secteur et pourvus de joints d'etancheite. Ces pistons sont juxtaposes et ont des vitesses angulaires a variation periodique de sorte que des volumes de travail dont la grandeur change periodiquement se forment entre les pistons rotatifs. A cet effet, l'arbre d'entrainement (1) comprend une came excentrique (1a) qui supporte un disque d'entrainement rotatif (3) a denture interieure (3a). Cette denture interieure (3a) s'engrene sur une roue dentee droite (4). Le disque rotatif (3) supporte des broches d'entrainement (8, 11, 14) qui sont chacune en liaison operationnelle avec un levier (7, 10, 13) et qui sont chacune reliees rigidement a un piston rotatif (15, 16, 17) par l'intermediaire d'un arbre creux (6, 9, 12).
