Abstract
A turbine includes a rotary shaft; a turbine impeller attached to the rotary shaft; a housing including a turbine housing that accommodates the turbine impeller; and a bearing that rotatably supports the rotary shaft. The turbine housing includes a first discharge path configured to discharge gas in a space, in which the bearing is provided, to an exhaust gas outlet port in the turbine housing. A bottom surface of the first discharge path is constituted of an inclined portion descending from a first inlet opening toward a first outlet opening, or is constituted of the inclined portion and a horizontal portion that continuously extends horizontally from the inclined portion.
Claims20
A turbine comprising:
- a rotary shaft;
- a blade attached to the rotary shaft;
- a housing including a turbine housing that accommodates the blade;
- and
- a bearing provided in the housing to rotatably support the rotary shaft,
- wherein the housing includes a first space in which the bearing is provided and the turbine housing includes a second space fluidly coupled to the first space, the second space at least partially surrounding the blade in the turbine housing,
- the turbine housing includes a discharge path configured to discharge gas contained in the first space to the second space,
- the discharge path includes an inlet that is located adjacent to the first space and opens into the first space and an outlet that is located adjacent to the second space and opens into the second space, and
- a bottom surface of the discharge path includes an inclined portion that descends from the inlet at a non-perpendicular inclined angle with respect to the rotary shaft, the inlet positioned at a higher elevation than the outlet.
A turbine comprising:
- a rotary shaft;
- a blade attached to the rotary shaft;
- a turbine housing that accommodates the blade;
- and
- a center housing which is connected to the turbine housing,
- wherein the center housing includes a first space and the turbine housing includes a second space fluidly coupled to the first space, the second space at least partially surrounding the blade in the turbine housing,
- the turbine housing includes a discharge path configured to discharge gas in the first space to the second space,
- the discharge path includes an inlet that opens into the first space and an outlet that opens into the second space, the outlet positioned at a lower elevation than the rotary shaft, and
- the discharge path descends from the inlet toward the outlet so as to discharge condensate water from the first space to the second space.
A turbine comprising:
- a rotary shaft;
- a blade attached to the rotary shaft;
- a center housing in which the rotary shaft is disposed;
- and
- a turbine housing which is connected to the center housing,
- wherein the center housing includes an inside space and the turbine housing includes an exhaust gas outlet port disposed downstream of the blade,
- the turbine housing includes a discharge path that fluidly couples the inside space to the exhaust gas outlet port,
- the discharge path includes an inlet that is located adjacent to the inside space and opens into the inside space and an outlet that is located adjacent to the exhaust gas outlet port and opens into the exhaust gas outlet port, and
- at least part of the discharge path descends from the inlet toward the outlet, the inlet positioned at a higher elevation than the outlet.
