摘要

A gas source (3) at a temperature below 200K is connected to a working gas pipe (4) supplying a user circuit (1, 2). An exchanger (6) transfers heat from a hot gas to the intermediate portion (5) of the gas pipe. At least one catalyst bed (8) can be floated by a mixture of fuel and combustive gases from a source (9), to generate the hot gas passing through the exchanger The fuel is an inferior alkyl or hydrogen and the combustive gas is oxygen. The catalyst contains at least one metal from platinum, palladium and rhodium. The sources of fuel and combustive gas are gas bottles (10, 11). The working gas is helium, with the helium source temperature between 4 and 90K. An Independent claim is included for a starting stage for a cryogenic motor which has an ergol reservoir (1) connecting to the working gas supply line for a system as described above
