Joerg Wuerz 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).

  • Fuel injection system for an internal combustion engine
    Patent number: 8371267
    Abstract: The invention relates to a high-pressure fuel pump comprising a drive shaft supported by bearings, and fuel flows through the bearings in a forced manner in such a way that the mechanical and thermal load-carrying capacity of the bearings, and thus the entire high-pressure fuel pump, is significantly increased.
    Type: Grant
    Filed: May 8, 2006
    Date of Patent: February 12, 2013
    Assignee: Robert Bosch GmbH

  • Vane pump with housing end wall having an annular groove and a pressure groove that communicate via a curved connecting groove
    Patent number: 7878779
    Abstract: The vane pump has a housing containing a rotor driven by a drive shaft. A number of grooves are distributed over the rotor circumference and extend in a substantially radial direction of the rotor, in each of which grooves a wing-shaped delivery element is guided in sliding fashion. The rotor is surrounded by a circumferential wall that extends eccentrically in relation to its rotation axis against which the radially outer ends of the delivery elements rest. Housing end walls of the pump housing adjoin the rotor in the direction of its rotation axis. An annular groove encompassing the rotation axis of the rotor is provided in at least one of the housing end walls and is situated opposite the radially inner regions of the grooves of the rotor and communicates with the pressure region via a connecting groove in the housing end wall. The connecting groove extends from the pressure region radially inward in the rotation direction of the rotor to the annular groove.
