<p>A turbo-charger in which a turbine wheel located in a turbine chamber is driven by an exhaust gas flow. A bypass passageway (6,8,9) extends around the chamber to enable exhaust gas to be diverted away from the turbine wheel. A valve (5) is mounted in the bypass passageway (6,8,9) and controlled so as to selectively open and close the passageway (6,8,9). The passageway (6,8,9) opens into the outlet (3) in a direction such that gas issuing from the passageway (6,8,9) is directed parallel to the direction in which gas flows through the outlet (3) from the turbine chamber. <IMAGE></p> |
