摘要： A valve assembly and air flow management assembly for use in an exhaust gas recirculation system capable of providing substantially zero air flow at closure, is described. The valve assembly includes a valve housing having a central axis bore, a rotatable support shaft disposed centrally within the housing, a flapper having an outer circumferential edge, the flapper operably connected to the support shaft and, a ring seal integral with the outer circumferential edge of the flapper, wherein the ring seal closes an opening between the flapper and the bore when the flapper is in the closed position. The outer circumferential edge of the flapper further includes a groove having the ring seal disposed within the groove, wherein the seal floats within the groove, eliminating thermal stress and providing improved sealing capabilities.

摘要： A compressor assembly (304) includes a compressor housing (312) having a main air inlet (324) and an annular wall (328) defining an inducer bore (325). A secondary inlet passage (322) is disposed around the inducer bore (325). The secondary inlet passage (322) has an inlet slot (320) operatively intersecting the inducer bore (325) to permit the entry of a fluid thereinto through an inlet port (327). The inlet slot (320) advantageously defines an augmented inducer diameter region (331). Preferably the secondary inlet passage (322) may be selectively partially or completely isolated from the main air inlet (324). A compressor wheel (318) is located in the compressor housing (312) and has a stepped portion (330) formed by at least one plurality of vanes (238) operatively associated with the augmented inducer diameter region (331) adjacent to the inlet slot (320) of the housing (312) to receive fluid therefrom.
