Abstract

L'invention concerne un système à piston alternatif, en particulier un moteur à combustion interne, comprenant au moins un cylindre (1) et un unique piston (2) qui se meut dans ce cylindre (1) et qui permet, en particulier, de comprimer des fluides gazeux, et un arbre d'entraînement (C1), en particulier en forme d'arbre de vilebrequin, auquel une extrémité d'une bielle (3) est reliée de manière excentrée. A son autre extrémité, la bielle (3) est accouplée cinématiquement au piston (2) et l'accouplement cinématique entre la bielle (3) et le piston (2) est formé par un premier et un deuxième système d'excentrique (4.1, 5.1, 6.1, 4.2, 5.2, 6.2) et chaque système d'excentrique (4.1, 5.1, 6.1, 4.2, 5.2, 6.2) présente au moins un support d'excentrique (4.1, 4.2) sur lequel est disposé un excentrique (5.1, 5.2) à une certaine distance par rapport à son axe de rotation (6.1, 6.2). Dans le premier système d'excentrique (4.1, 5.1, 6.1), l'axe de rotation (6.1) du support d'excentrique (4.1) est fixe par rapport à la bielle (3) et l'excentrique (5.1) est fixe par rapport au piston (2) et, dans le deuxième système d'excentrique (4.2, 5.2, 6.2), l'axe de rotation (6.2) du support d'excentrique (4.2) est fixe par rapport au piston (2) et l'excentrique (5.2) est fixe par rapport à la bielle (3). Les deux axes de rotation (6.1, 6.2) des supports de rotation (4.1, 4.2) des deux systèmes d'excentrique (4.1, 5.1, 6.1, 4.2, 5.2, 6.2) sont en particulier espacés parallèlement l'un de l'autre et perpendiculaires à la ligne centrale (Z) du piston se trouvant dans la direction de mouvement linéaire.
