A compressor wheel for a turbocharger comprising a wheel (5) having a thrust surface (54) and a hub (56) and a seal ring groove (52) for receiving a ring seal (7) to resist lubrication oil leakage and sealingly engage the center housing.

An integrated bearing system with journal and thrust bearings is incorporated in a single unit centrally pinned to the bearing housing and having integral thrust surface lubrication grooves and journal surface lubrication grooves in combination with turbin...

A compressor for a turbocharger comprising a wheel (5) having a thrust surface (54) and a hub (56) and a bore for attachment to a shaft, wherein the bore has a threaded portion (60).

The invention recites a microturbine system comprising a housing and a turbine including a rotary element having a shaft supported by the housing and rotatable about a rotary axis. A starter wheel is coupled to the shaft and rotatable in response to a stre...

In the layout of two concentric shafts (15,16) a sleeve (38) surrounding the shafts carries two sealing joints (23,39). A bearing (18) supports the external line of shafts near the front end and a bearing retaining nut (19) is screwed on the front end. A s...

An improved turbocharger for railway locomotive sized engines includes, in a preferred embodiment, first and second axially spaced ball bearings supporting a rotor with the first bearing being a hybrid ceramic ball bearing mounted to accept both radial and...

The bearing chamber, for the turbine shaft (1, 2), is sealed inside the turbine. It has an oil outlet line (11) going to an oil collection cavity. Due to the design of the outlet line and the sealing elements (8a, 8b), the pressure in the bearing chamber i...
