Abstract
Moteur thermique à piston de travail double effet, solidaire d'un piston de pré-compression double effet, ceci afin d'obtenir deux explosions par tour s ur une seule bielle. L'invention concerne un moteur thermique doté d'un ou plusieurs pistons quadruple effet, destiné à faire travailler la (ou les) bielles (209) à la compression et à l'extension sous l'effet de deux explosions par bielle et par tour. Les chambres de pré-compression (320) (32 1) sont équipées de clapet d'entré (238) et de clapet de sortie (282) (203). Le s gaz pré-comprimés sont destinés à gaver les chambres de travail (323) (324) lorsque simultanément les soupapes d'admission (213) et d'échappement (229) sont ouvertes. Le moteur selon l'invention est destiné aux mêmes utilisation s que les moteurs thermiques actuels.Double-acting working piston heat engine, integral with a double-acting pre-compression piston, in order to obtain two explosions per revolution on a single connecting rod. The invention relates to a heat engine provided with one or more quadruple-acting pistons, intended to work the connecting rod (s) (209) in compression and extension under the effect of two explosions per connecting rod and per revolution. . The pre-compression chambers (320) (32 1) are equipped with an inlet valve (238) and an outlet valve (282) (203). The pre-compressed gases are intended to force-feed the working chambers (323) (324) when simultaneously the intake (213) and exhaust (229) valves are open. The engine according to the invention is intended for the same uses as current heat engines.
