CA 2477972

A rotary engine, pump or compressor (102) with a framework is provided with intake/exhaust ports in end plates (219) and a rotatably mounted block mounted there-between. In the four cylinder embodiment of this invention, first and second opposing cylinder sets (113, 114) are mounted in the block and each cylinder set includes first and second opposing cylinders (130, 140) with proximal ends and terminal ends (143, 134), and with transfer ports (132, 142) disposed to alternately form passageways with the intake and exhaust ports as the cylinders rotate with the block. Each crankset includes a crankpin (161) eccentrically mounted to the piston set to rotate about a crankpin axis, a crankpin gear (163) fixed to the crankpin, an internal gear (162, 220) fixed relative to the first cylinder set, the internal gear having an internal gear configured to mate with the crankpin gear as the crankpin gear rotates within the internal gear, wherein the eccentric rotation of the crankpin offsets the rotation of the crankpin gear within the internal gear to provide approximately linear movement of the piston heads within the first and second cylinders and such that the crankpin also rotates about a crank-set axis; and an inward side of the crankpin being eccentrically mounted to an inner crank gear (167, 171), such that the rotation of the crankpin also rotates the inner crank gear about the crank-set axis (117); wherein the generally linear movement of the circular base aperture (160, 212, 370) of the piston set drives the crankpin gear to rotate around within the internal gear, thereby driving the crankpin to rotate about the crankpin axis; the inner crank gear mating with a drive-shaft gear (172) such that the rotation of the inner crank gear rotates the drive-shaft. The rotation of the block is provided by any one of a number of different mechanisms.

L'invention concerne un moteur, une pompe ou un compresseur (102) rotatif, pourvu d'une structure et d'orifices d'admission/d'évacuation dans des plaques (219) d'extrémité, et d'un bloc monté de manière rotative entre celles-ci. Dans un mode de réalisation de l'invention à quatre cylindres, un premier et un second ensemble de cylindres opposés (113, 114) sont montés dans le bloc et chaque cylindre comprend un premier et un second cylindre opposés (130, 140) avec des extrémités proximales et des extrémités terminales (143, 134), et avec des orifices (132, 142) de transfert disposés de manière à former des passages en alternance avec les orifices d'admission et d'évacuation tandis que les cylindres tournent avec le bloc. Chaque ensemble manivelle comprend un maneton (161) monté excentriquement sur l'ensemble piston pour tourner autour d'un axe de maneton, une transmission (163) de maneton fixée au maneton, une transmission interne (162, 220) fixée au premier ensemble de cylindres, la transmission interne étant formée d'une transmission interne configurée pour s'adapter à la transmission du maneton lorsque la transmission du maneton tourne dans la transmission interne, et un côté intérieur du maneton étant monté excentriquement dans une transmission (167, 171) de manivelle interne, de manière que la rotation du maneton génère également la rotation de la transmission de manivelle interne autour de l'axe (117) de l'ensemble manivelle. Le mouvement généralement linéaire de l'ouverture de base circulaire (160, 212, 370) de l'ensemble piston entraîne la rotation de la transmission du maneton autour de la transmission interne, entraînant ainsi la rotation du maneton autour de l'axe du maneton, la transmission de manivelle interne étant adaptée à la transmission (172) d'un arbre de transmission de manière que la rotation de la transmission de manivelle interne génère la rotation de l'arbre de transmission. La rotation du bloc est obtenue à l'aide d'une diversité de mécanismes différents.
