The present inventions concern oscillating piston engines and oscillating piston compressors of high efficiency. This is achieved by an arrangement in which the piston floor (1) lies on a circular cylinder whose centre coincides with centre (2) of the connecting rod bearing and the inner face (4) of the cylinder head lies on a circular cylinder whose centre coincides with the centre (5) of the crankshaft bearing; (1) and (4) are in mutual rolling sealing contact in the vicinity of the top dead centre. Additional measures help to ensure, for an engine, that the crankshaft is driven before the top dead centre or, for a compressor, that optimal compression with regard to flow is achieved with the smallest possible dead volume. Structural details aimed at optimizing this and similar oscillating piston machines are also disclosed.
L'invention concerne des moteurs et des compresseurs à pistons oscillants permettant d'obtenir des rendements élevés. Ce résultat est obtenu grâce au fait que le fond de piston (1) prend appui sur un cylindre circulaire ayant comme centre le centre (2) du coussinet de bielle, et la surface intérieure (4) de la tête de piston prend appui sur un cylindre circulaire ayant comme centre le centre (5) du palier de vilebrequin, les éléments (1) et (4) roulant l'un sur l'a utre, de manière étanche, dans la zone du point mort haut. Grâce à des dispositions complémentaires, on obtient ainsi, pour le moteur, un entraînement du vilebrequin avant le point mort haut et, pour le compresseur, une compression optimale conforme à l'écoulement, avec un volume mort minimal. Des particularités constructives visant à optimiser l'invention, ainsi que des variantes de tels moteurs à pistons oscillants, sont décrites.
