Abstract
A turbine comprising a housing, a turbine wheel and at least one movable member. The housing has an interior, an inlet for allowing fluid to enter the interior and an outlet for allowing the fluid to exit the housing. The turbine wheel has turbine blades located in the housing. The at least one movable member is located within the housing and is positioned in a fluid path between the inlet and the turbine blades for selectively controlling a flow of fluid to the turbine blades in the housing.
Claims41
A turbine comprising:
- a housing having an interior, an inlet for allowing fluid to enter the interior and an outlet for allowing the fluid to exit the housing;
- a turbine wheel having turbine blades located in the housing;
- and
- at least one movable member within the housing and positioned in a fluid path between the inlet and the turbine blades for selectively controlling a flow of fluid to the turbine blades in the housing;
- the at least one movable member being configured to substantially stop the flow of fluid to the turbine blades.

A turbocharger subassembly comprising:
- a housing having a substantially disc-shaped interior, an intake channel having an inlet and an exit leading into the interior, the intake channel being adapted for accepting fluid therein and supplying the fluid to the interior, the housing further having an axial outlet for allowing the fluid to exit the housing;
- a blade wheel in the housing;
- and
- a single rotating throttle plate within the housing and positioned between the inlet of the intake channel and the blade wheel for selectively controlling a flow of fluid to the blade wheel in the housing and a tangential velocity of the fluid in the disc-shaped interior of the housing.

A turbocharger subassembly comprising:
- a housing having an interior, an inlet for allowing fluid to enter the interior and an outlet for allowing the fluid to exit the housing;
- a blade wheel in the housing;
- and
- a single rotating member surrounding the blade wheel within the housing and positioned between the inlet and the blade wheel for selectively controlling a flow of fluid to the blade wheel in the housing;
- the housing including a stationary wall surrounding the blade wheel, the stationary wall including at least one first opening;
- and
- the single rotating member including at least one second opening configured to be selectively aligned with the at least one first opening as the single rotating member is rotated to control an amount of the fluid reaching the blade wheel.
4 more elements
A turbocharger assembly comprising:
- a turbine including a turbine housing having an inlet and outlet, the turbine further including a turbine wheel having turbine blades;
- a compressor including a compressor housing having an inlet and an outlet, the compressor further including a compressor wheel having compressor blades;
- and
- a shaft extending between and into the turbine housing and the compressor housing, the shaft having the turbine wheel connected thereto adjacent a first end of the shaft and the compressor wheel connected thereto adjacent a second end of the shaft;
- wherein the turbine includes at least one movable member within the turbine housing and positioned between the inlet and the turbine wheel for selectively controlling a flow of fluid to the turbine wheel;
- wherein the fluid flowing through the turbine rotates the turbine wheel and the shaft, thereby rotating the compressor wheel in the compressor to compress fluid flowing through the compressor;
- and
- wherein the at least one movable member is configured to substantially stop the flow of fluid to the turbine blades.
