Turbocharger With An Annular Rotary Bypass Valve
A turbocharger includes an annular bypass passage with an annular bypass valve (70) disposed therein. The bypass valve includes a fixed annular valve seat (72) and a rotary annular valve member (74) disposed against the valve seat. The valve member (74) is rotatable about the axis for varying a degr...

| description | A turbocharger includes an annular bypass passage with an annular bypass valve (70) disposed therein. The bypass valve includes a fixed annular valve seat (72) and a rotary annular valve member (74) disposed against the valve seat. The valve member (74) is rotatable about the axis for varying a degree of alignment between orifices (75) in the valve seat (72) and valve member (74) so as to form flow passages having a flow area A for exhaust gas. The orifices (75) are shaped to provide a first phase of evolution of the flow area A from zero up to a value A 1 and then a second phase of evolution from the value A 1 up to a value A 2 , 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 (74), with a distinct break point in the curve between the first and second phases. |
