Abstract

Variable turbocharger apparatus (2) comprising a housing (4), a compressor (6) mounted for rotation in the housing (4), a turbine (12) mounted for rotation in the housing (4), a first inlet (16) for enabling air to be conducted to the compressor (6), an outlet (18) for air from the compressor (6), a second inlet (20) for enabling exhaust gases from an engine to be conducted to the turbine (12), a chamber (22) which surrounds the turbine (12) and which receives the exhaust gases from the second inlet (20) before the exhaust gases are conducted to the turbine (12), and a piston (24) which is positioned between the turbine (12) and the housing (4) and which is slidable backwards and forwards to form a movable wall separating the turbine (12) from the chamber (22) which surrounds the turbine (12), the piston (24) having a plurality of vanes (102), the piston (24) being such that in its closed position it terminates short of an adjacent part of the housing (4) so that there is always a gap between the end (30) of the piston (24) and the adjacent part (26) of the housing (4), the piston (24) being biased to its closed position against pressure from exhaust gases in the chamber (22), and the piston (24) being movable by fork means (21) which locates in a groove (36) in the piston (24).
