Abstract

Moteur à combustion interne à deux ou à quatre temps et à allumage par bougie ou par compression, dans lequel la transmission de la pression des pistons est centralisée. Il peut trouver des applications dans les domaines les plus divers: l'industrie de l'automobile et des tracteurs, les locomotives, les navires, les machines agricoles automotrices, les générateurs, etc. Afin d'augmenter l'efficacité de la transformation du mouvement linéaire des pistons en mouvement rotatif du vilebrequin, les points centraux des ponts de liaison (6) sont articulés aux éléments diagonaux d'équilibrage (8) par des boulons (7), lesquels éléments oscillent de manière coaxiale par rapport aux tourillons du vilebrequin (9) sur le maneton duquel s'appuie librement par l'intermédiaire de bagues (11) la tête d'une bielle (10), tandis que la crosse d'une bielle s'appuie librement sur l'un des boulons de piston (5).
