  • Patent number: 7025579
    Abstract: A bearing system for a turbocharger shaft includes an elongated bearing carrier with two anti-friction ball bearings mounted in its ends and with a radially extending flange at one end that cooperates with stationary housing portions and carries thrust loads of the rotor in both directions. The elongated bearing carrier is supported within the housing by axially spaced elastic supports which permit the rotating assembly to rotate about its mass center and provide a shock and vibration cushion. The elongated bearing carrier and housing cooperate to provide a coolant cavity which communicates with the outside periphery of the elongated bearing carrier between the axially spaced elastic supports, which also act as coolant seals between the elongated bearing cavity and the bearing housing.
    Type: Grant

The coolant cavity protects the bearing system and anti-friction ball bearings from heat conducted from the exhaust gas-driven turbine and also cools the housing.

  • Patent number: 6340441
    Abstract: A multi-layered guide wire that uses separate layers to achieve desired guide wire characteristics. Each of the layers may enhance one or more of the desired guide wire characteristics, with the combination of layers providing the desired combination of guide wire characteristics. Each of the layers may be provided over the entire guide wire, or only over selected portions of the guide wire. Further, selected layers may be co-extruded over the guide wire, which may reduce the manufacturing costs associated therewith.

  • Patent number: 4815184
    Abstract: A water-cooled turbocharger is fabricated employing a coreless die casting process. Instead of casting a complete passage in the bearing housing of the turbocharger, an open ended channel is cast into the housing and then sealed off by a mating seal plate. O-rings or other sealing materials are used to seal the mating joints to prevent pressurized cooling water from leaking to the outside or into the internal bearing housing area.

  • Patent number: 4504187
    Abstract: A method of operating turbochargers for use with internal combustion engines and a turbine housing therefor wherein the housing is uniquely configured so as to be able to be mounted in the engine compartment in a variety of modes and wherein the turbocharger may or may not be used in conjunction with a wastegate control. The unique configuration of the turbine housing permits the passage of exhaust gas through the interior of the turbine housing and more specifically through the extent of the internal scroll thereof wherein the exhaust gas imparts to the turbine operation peak efficiency before the driving gas is vented through a wastegate passageway at the terminus of the turbine housing as opposed to the entry thereof. The exhaust gases may also be bypassed from a point between the entry and terminus of the internal scroll.
