摘要： A turbocharger includes an annular bypass passage with an annular bypass valve disposed therein. The bypass valve includes a fixed annular valve seat and a rotary annular valve member disposed against the valve seat. The valve member is rotatable about the axis for varying a degree of alignment between orifices in the valve seat and valve member so as to form flow passages having a flow area A for exhaust gas. The orifices are shaped to provide a first phase of evolution of the flow area A from zero up to a value A1 and then a second phase of evolution from the value A1 up to a value A2, and such that the first and second phases have distinctly different slopes on a curve of flow area versus rotational position of the valve member, with a distinct break point in the curve between the first and second phases.

摘要： A turbocharger includes an annular bypass volute to allow exhaust gas to bypass the turbine wheel. An annular bypass valve is disposed in the bypass volute. The bypass valve comprises a fixed annular valve seat and a rotary annular valve member arranged coaxially with the valve seat. The valve member is disposed against the valve seat and is rotatable about the axis for selectively varying a degree of alignment between respective orifices in the valve seat and valve member. The valve member is rotatably driven by a rotary actuator and drive linkage that rotates about an axis parallel to and offset from the axis about which the valve member rotates.
