Abstract
A turbine (32) section of a turbocharger (30) includes a turbine wheel (37) disposed in a turbine housing (33), the turbine housing (33) defining a gas inlet (34), a volute configured to direct gas from the inlet (34) to the turbine (32) wheel, and a gas outlet. A rotary diverter valve (100, 200) is disposed in the gas inlet (34) upstream of the volute, and provides three modes of controlling exhaust gas flow about the turbocharger (30).
Claims15
A cylindrical rotary valve configured to control fluid flow through a fluid passage, the valve comprising
- a first end,
- a second end that is opposed to the first end,
- a side surface that extends between the first end and the second end,
- a first inlet opening formed in the side surface,
- a first outlet opening formed in the side surface,
- a first valve passage that connects the first inlet opening to the first outlet opening,
- a second inlet opening formed in the side surface,
- a second outlet opening formed in the side surface, and
- a second valve passage that connects the second inlet opening
- to the second outlet opening,
- wherein
- the second valve passage is separate from the first valve passage,
- the first inlet opening, the first outlet opening, and the second inlet opening are each disposed between the first end and a mid portion of the valve, and
- the second outlet opening is disposed between the mid portion and the second end.

A turbocharger comprising
- a turbine section including a turbine housing and turbine wheel disposed in the turbine housing, the turbine housing defining a gas inlet, a volute configured to direct gas from the inlet to the turbine wheel, and a gas outlet;
- and
- a rotary valve disposed in the gas inlet in such a manner that a rotational axis of the valve extends transverse to a direction of gas flow through the inlet, the valve comprising:
- a first end,
- a second end that is opposed to the first end,
- a side surface that extends between the first end and the second end,
- a longitudinal axis that extends through the first and second ends and coincides with the rotational axis of the valve,
- a first inlet opening formed in the side surface,
- a first outlet opening formed in the side surface,
- a first valve passage that connects the first inlet opening to the first outlet opening,
- a second inlet opening formed in the side surface,
- a second outlet opening formed in the side surface, and
- a second passage that connects the second inlet opening to the second outlet opening,
- wherein
- the second passage is separate from the first passage, and
- the first inlet opening, the first outlet opening, and the second inlet opening are each positioned so as to communicate with the gas inlet for certain rotational orientations of the valve, and the second outlet opening is positioned so as to be able to communicate with the gas outlet for certain rotational orientations of the valve.
