摘要： Disclosed is a turbine comprising a turbine wheel, a turbine scroll passage defined in a turbine casing around the turbine wheel for introduction of gas to the turbine wheel, and an axial central passage defined in the turbine casing for ejection of gas from the turbine wheel, wherein: a plurality of variable nozzles are arranged outside of a throat section having a locally minimum cross section which is defined in the turbine casing around the turbine wheel. The variable nozzles may be defined by fixed vanes and moveable vanes which cooperate with each other in such a manner that each of the moveable vanes and the corresponding fixed vane define a substantially smooth and continuous airfoil. The moveable vanes may be pivotally supported by a back plate of the casing while the fixed vanes may be integrally provided with a fixed vane member having a disk portion which defines a surface opposing the inner surface of the back plate. The moveable vanes may rotate along and between these mutually opposing surfaces for varying the cross section of the nozzles defined between the fixed vanes and the moveable vanes.

摘要： In a variable nozzle structure for a turbine, moveable vanes for controlling variable cross section nozzles which lead to a turbine wheel are actuated by a drive unit which comprises an actuator for causing a linear motion to a rod member, a lever arm member which is pivotally supported by a part of the turbine casing and is connected to the rod member at its one end so as to be able to rotate about its pivot point with respect to a turbine casing when the rod member is driven linearly, a crank arm member which is integrally connected to a pin shaft which is securely attached to each of the moveable vanes and pivotally supports the corresponding moveable vane, and an engagement member which is fixedly attached to the lever arm member and is engaged with the crank arm member so as to cause the rotational motion of the crank arm member when the lever arm member is rotatively driven by the rod member. Thereby, accurate control of the variable nozzles can be accomplished with a simple structure.
