Abstract

See full text

A vane (234) is provided which reduces leakage of gas in a variable geometry turbocharger (210) from the high pressure side of the vane (234) to the low pressure side of the vane (234). The vane (234) can have a channel (330, 430) along a gas bearing surface (325, 425) for reducing the leakage. The channel (330, 430) can be defined at least in part by sideplates (300, 350). The sideplates (300, 350) can be integrally cast with the rest of the vane (234). At least one of the sideplates (300, 350) can have a hole therein for a vane shaft (228) which allows movement of the vane (234) for gas flow control. The sideplates (300, 350) can have edges (301, 351) that conform to the shape of the gas bearing surface (325, 425).
