Abstract (en)

[origin: WO2005010322A1] The invention relates to a compressed air engine comprising a stator (1) and a rotor (2), cylinders and concentrics describing a volume chamber (V), at least one pipe (P) for supplying compressed air to at least one decompression chamber (Va) belonging to said volume (V) and defined by a piston (7) and retractable bottom (8) and at least one pipe (6) for removing residual air (R) at the end of a decompression cycle. The inventive engine is characterised in that each air supply pipe (5) is connected to means for injecting a defined quantity and volume of compressed air into the decompression chamber when the piston (7) moves on the supply pipe (5).
