Hans-Jurgen Rudolph has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 6766645
    Abstract: This invention relates to configuration of at least two exhaust gas turbochargers on an internal combustion engine with a plurality of cylinders, in particular in a motor vehicle, in which the two turbine housings are connected to the exhaust gas system of the internal combustion engine and are immediately adjacent to each other and one turbine is always connected to one compressor by means of a drive shaft, the drive shafts being rotatably mounted in corresponding bearing housings. In order to prepare a design which is advantageous from the viewpoint of structure and production technology, it is proposed that the turbine housings are oriented such that the drive shafts be positioned at least approximately in alignment with each other and that the bearing housings be connected to the turbine housings on both sides.

  • Patent number: 6189396
    Abstract: The invention concerns a control arrangement for an automatic electrohydraulically controlled transmission. In order to reduce expenditure on parts and assembly, the hydraulic control system and electronic control system are mounted directly adjacent each other and plug-in connections are provided between the solenoid valves of the hydraulic control system and the electronic control system. The hydraulic control system (20) substantially comprises two duct panels (28,30) in which control ducts, piston slides and solenoid valves (not shown) are disposed for controlling the conical plates and couplings of the transmission. The pressurized hydraulic fluid is fed directly into these duct panels from the pump (29). The electronic control system (22) has a single central connection (36) which is secured in the transmission housing cover (42) by an annular seal. Rotational speed sensors for the transmission shafts and temperature and pressure sensors are integrated into the control unit.
