  • Patent number: 6913439
    Abstract: An exhaust gas turbocharger for an internal-combustion engine has a turbine housing and compressor housing in which a turbine wheel and a compressor impeller are connected with one another shaft. The turbine housing has a spirally-extending inlet duct for the exhaust gases. Devices for the flow deflection can be provided in the inlet duct. As a result, the thermal stress as well as the efficiency of an exhaust gas turbocharger with a spirally extending inlet duct for the exhaust gases are improved.
    Type: Grant

  • Patent number: 4527517
    Abstract: A water pump for a reciprocating piston internal combustion engine is driven by a shaft located between the camshaft and crankshaft. The intermediate shaft which is driven by and coupled to the crankshaft at one wall of the crank housing. The water pump is located in a remote wall of the crank housing, which itself forms one half of the pump containment. A dish-shaped housing half screws into the remote wall to contain the pump. The intermediate shaft is connected to the pump wheel of the water pump by a hollow shaft which passes longitudinally through the crank housing. Together with the bearings, securing elements, sealing rings and a bearing flange, the shaft forms a structural unit which may be pre-assembled and easily inserted into the engine.
