## Abstract

A turbocharger (300) having a rotatable shaft (312) passing through a bearing housing (303) with a turbine-end bearing support (580) with a support bar (600). A turbine-end bearing support (580) may include the support bar (600) with radial supports (610) and (620) connected to each opposite side (492) and (494) of cavity (496) of the bearing housing (303) wherein oil can flow in recesses (640) and (650) above the radial supports (610) and (620). Each radial support (610) and (620) of the support bar (600) is preferably integrated in the corresponding side (492) and (494). A turbine-end bearing support (580) may also include the support bar (600) with a rod portion (622) forming a bottom tie support bar (612) that supports the bottoms of both bearing supports (490) and (580), which are top-supported by the bearing housing (303). Each support bar (600) is preferably integral with the bearing support (580).

## Claims

### Claim 1

A turbocharger (300) having a rotatable shaft (312) passing through a bearing housing (303), the bearing housing having a turbine end and a compressor end and comprising:
a turbine-end bearing support (580) for supporting a journal bearing of the rotatable shaft (312) in the bearing housing (303), the turbine-end bearing support including a support bar (600) having radial supports (610, 620) extending from the turbine-end bearing support (580) and connected respectively to opposite sides (492, 494) in a cavity (496) of the bearing housing (303) wherein oil can flow in recesses (640, 650) of the cavity (496) above the radial supports (610, 620) adjacent to the bearing support (580).

### Claim 2 (depends on 1)

The turbocharger of claim 1 wherein the support bar (600) is integral with the turbine-end bearing support (580) and the radial supports (610, 620) of the support bar (600) are each integral with the respective side (492, 494).

### Claim 3 (depends on 1)

The turbocharger of claim 1 further comprising a compressor-end bearing support (490) for a compressor-end journal bearing (316) wherein the turbine-end bearing support (580) supports a turbine-end journal bearing (320) in the bearing housing (303).

### Claim 4 (depends on 1)

The turbocharger of claim 1 wherein a portion of the support bar (600) with its radial supports (610, 620) forms a substantially planar portion (630) above a portion of the cavity (496).

### Claim 5 (depends on 1)

The turbocharger of claim 1 wherein a cavity portion (606) in the bearing housing (303) extends above the turbine-end bearing support (580).

### Claim 6

A turbocharger (300) having a rotatable shaft (312) passing through a bearing housing (303) (303), the bearing housing having a turbine end and a compressor end and comprising:
a turbine-end journal bearing support (580) supporting a turbine end journal bearing (320) for the rotatable shaft (312) in the bearing housing (303) with a support bar (600) having radial supports (610, 620) integral with opposite sides (492, 494) of a cavity (496) of the bearing housing (303) wherein oil can flow in recesses (640, 650) above the radial supports (610, 620) adjacent to the journal bearing support (580), and
