Patent number: 6470855Abstract: A high-pressure fuel reservoir is proposed in which the hydraulic connection between the connection fitting and the reservoir chamber is produced by a number of connecting bores. This reduces the stress peaks in the vicinity of the intersections of the connecting bore and reservoir chamber so that the compression capacity of the high-pressure fuel reservoir increases.Type: GrantFiled: September 7, 2001Date of Patent: October 29, 2002Assignee: Robert Bosch GmbHInventors: Kurt Frank, Helmut Knoedl, Henning Kreschel, Friedrich Boecking, Steffen Jung

Publication number: 20020139869Abstract: A high-pressure fuel system for internal combustion engines, having a housing that contains two high-pressure bodies. The high-pressure bodies rest with contact surfaces at least indirectly against each other and are pressed against each other by means of a tensioning device. A supply conduit is embodied in the high-pressure bodies, which carries highly pressurized fuel and passes through the contact surfaces of the two high-pressure bodies. A sealing film is disposed between the two high-pressure bodies, which encompasses the passage of the high-pressure conduit and thus assures a favorable seal.Type: ApplicationFiled: March 26, 2002Publication date: October 3, 2002Applicant: Robert Bosch GmbHInventors: Michael Kurz, Kurt Frank, Juergen Hanneke, Marcus Haefele, Friedrich Boecking

Patent number: 6092500Abstract: A delivery device for fuel to an internal combustion engine, which includes a fuel reservoir. After the engine is shut off or in the event of an accident, there is the danger that the pressurized fuel present in the fuel reservoir will escape from the delivery device. A blocking device is provided on the fuel reservoir, which after the engine is shut off or after an accident, the blocking device engages with an actuation rod that is provided with detent teeth, by means of an electromagnetically actuated locking pin and thus prevents a force impingement of a compression spring on the movable wall of the fuel reservoir. By use of the blocking devices the pressure in the fuel line is completely reduced even after the escape of small fuel quantities. The delivery device is suited for mixture-compressing internal combustion engines with externally supplied ignition.Type: GrantFiled: November 6, 1998Date of Patent: July 25, 2000Assignee: Robert Bosch GmbHInventors: Kurt Frank, Detlef Classe, Albert Gerhard, Ulrich Projahn
