Document Type and Number:
WIPO Patent Application WO2004083725
Kind Code:
A3
Abstract:
According to the invention, which applies to a gas-operated apparatus comprising a first chamber (11) for the precompression of a combustible gas (12) injected thereinto and generation of a flame, and a second, propulsion, chamber (15), and means (16, 17) for placing the two chambers in communication, these means being designed to allow the flame to pass, the power of the apparatus is adjusted by adjusting (17) the communication between the two chambers (11, 15). The volume of gas injected directly (42) into the propulsion chamber (15) can also be adjusted. Alternatively, the rotational speed of the fan (13) with which the first chamber (11) is equipped can be adjusted.
