Abstract

Expansion turbine (1) for the expansion of gas, comprising a housing (7), a substantially annular side channel (13) located in the housing (7) for a gas to be expanded, at least one gas inlet opening (26) which is configured in the housing (7) and is in flow connection with the side channel (13) for introducing the gas to be expanded therein, at least one gas outlet opening (27) configured in the housing (7) to discharge the expanded gas from the side channel (13), the gas outlet opening (27) being in flow connection via the side channel (13) with the gas inlet opening (26), and a wheel (6) rotatably mounted in the housing (7) with at least one wheel blade (5) arranged in the side channel (13) to be driven by the gas flowing into the side channel (13).
