The object of this invention is to propose a variable capacity turbine, requiring neither adjustment process of the full-opening position and the perfect closing position nor the dedicated full position stopper, in which the adjustment works for setting up...

The variable-capacity turbine according to this invention is provided with a nozzle adjustment mechanism (100), having a nozzle drive components, a lever (1) and nozzle vane (2), would all be housed at the inner side of the scroll (11) in the turbine casin...

Variable nozzle drive mechanism with a link plate (112), which can operate all the nozzle vanes smoothly and synchronously. The nozzle vanes (104) are supported in such a way that the nozzle vanes are free to rotate between the open and closed positions on...

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 ...

A variable geometry turbocharger in which a bill-like projection portion is arranged in a part of an outer periphery of a flow passage spacer, and the projection portion is protruded to a turbine rotor side at a predetermined angle or the projection portio...
