摘要： A turbocharger (20) having a sliding piston type variable turbine nozzle includes a tubular piston (40) disposed in a bore (32) of the turbine housing and axially slidable relative to the turbine housing, the piston being slidable between a closed position and an open position for blocking the nozzle (36) opening by an amount dependent on axial positioning of the piston so as to regulate flow into the turbine wheel (30). The turbine housing (32) and piston (40) are structured and arranged to define a cavity (50) therebetween, and there are seals (52a, 52b) between the turbine housing and piston for sealing the cavity, the turbine housing (32) defining a passage (54) connecting with the cavity (50) and adapted to be connected with a fluid source such that application of differential fluid pressure through the passage to the cavity urges the piston to axially slide in the turbine housing.

摘要： A turbine housing assembly includes a tubular piston disposed in a bore of a turbine housing and axially slidable between a closed position and an open position for blocking a nozzle by an amount dependent on axial positioning of the piston. A bypass control member is disposed in the turbine housing and is slidable between a no-bypass position closing a bypass passage and a open bypass opening the bypass passage. The piston is structured and arranged to slide relative to the bypass control member for a part of a full stroke of the piston from the closed position toward the open position thereof, and then to engage the bypass control member and cause the bypass control member to slide together with the piston as the piston further slides toward the open position thereof such that the bypass control member is moved toward the bypass position.

摘要： A non-rotating turbocharger waste gate valve (130) for use in gasoline, diesel or other internal combustion engines. The cross section of the shaft (120) of valve (130) is oblong or otherwise non-circular, thus preventing rotation of valve (130) even under high load conditions. The elimination of valve rotation greatly reduces valve wear and increases the useful life of valve (130).
