Patent number: 7178511Abstract: In an apparatus (12) for controlling a pressure in a fuel inflow line of a motor vehicle, a shutoff valve (20) and a pressure limiting valve (21) are arranged in a connection (19). The connection (19) is arranged between an inflow junction (16) which leads to the inflow line and an outflow junction (17) which is led into a fuel container. The pressure limiting valve (21) opens above a first pressure and throttles the flow of the fuel through the connection (19). The shutoff valve (20) closes above a second pressure, the second pressure being higher than the first pressure. This ensures that, when a fuel delivery unit is at a standstill, the pressure in the inflow line does not exceed the first pressure and that, during operation of the delivery unit, the pressure in the inflow line can rise above the second pressure and an internal combustion engine of the motor vehicle is supplied sufficiently with fuel.Type: GrantFiled: January 20, 2005Date of Patent: February 20, 2007Assignee: Siemens AktiengesellschaftInventors: Lothar Dickenscheid, Bernd Herzog

Patent number: 6708673Abstract: In a fuel feed unit, two anti-surge pots are connected to one another within a fuel tank by means of a connecting element. For installation, the anti-surge pots are introduced into the fuel tank singly through an installation opening, and are then connected to one another. This means that only a single installation opening is required in the fuel tank for two anti-surge pots.Type: GrantFiled: December 12, 2002Date of Patent: March 23, 2004Assignee: Siemens AktiengesellschaftInventors: Bernd Herzog, Helmut Nather

Publication number: 20030226548Abstract: A fuel feed unit for a motor vehicle, having a pressure-limiting valve arranged in a working fluid line of a suction jet pump which is arranged within a surge chamber of a fuel tank. Excess fuel therefore passes directly into the surge chamber via an outlet of the pressure-limiting valve. Unnecessary circulating of the fuel in the fuel tank is therefore avoided.Type: ApplicationFiled: April 8, 2003Publication date: December 11, 2003Applicant: Siemens AGInventors: Bernd Herzog, Helmut Nather
