Abstract
The object of this invention is to eliminate the quantity of exhaust gas supplied to the turbine without going through the channels between the nozzle vanes provided in a variable-capacity turbocharger. The nozzle unit 100 in the turbocharger 10 has; a mounting plate 102 and a side plate 104 installed in a recession 20 provided in the housing 20 in such a way that the side plate can move in the recession, both of which are provided parallel to the turbine shaft; a pushing means 116, 150 to push the side plate toward the mounting plate 102; and a limiting means 108 to limit the movement of the side plate parallel to the turbine shaft toward the mounting plate 102.
Claims4
A variable-capacity turbocharger which controls the opening degree of the nozzle vanes, comprising:
- a turbine provided in a housing, which is free to rotate on a turbine shaft;
- a plurality of nozzle vanes arranged in nozzle units around said turbine in said housing;
- a link plate which rotates freely around said turbine provided in said housing, which is connected to said nozzle vanes by means of a plurality of levers, and which continuously moves said nozzle vanes synchronously between the open and closed positions;
- an actuator outside the housing, which is connected to said link plate through a transmission mechanism;
- wherein said nozzle unit comprises:
- a mounting plate fixed to the housing and a side plate installed in a recession provided in the housing in such a way that said side plate can move in said recession, both of which are provided parallel to the turbine shaft;
- a pushing means to push said side plate toward said mounting plate;
- and
- a limiting means to limit the movement of said side plate parallel to the turbine shaft toward said mounting plate.
