A turbocharger in which a turbine wheel located in a turbine chamber is driven by an exhaust gas flow. A bypass passageway extends around the chamber to enable exhaust gas to be diverted away from the turbine wheel. A valve is mounted in the bypass passageway and controlled so as to selectively open and close the passageway. The passageway opens into the exhaust gas outlet in a direction such that gas issuing from the passageway is directed in a substantially annular form and in a substantially downstream direction.
