Patent number: 5301874Abstract: In electromagnetically actuatable valves, an adjusting sleeve is pressed into the flow bore of a core in order to adjust the spring force of a restoring spring. Because the known adjusting sleeves, for instance having two beads, have a sharp-edged embodiment in the region toward the flow bore, chips can be produced when they are pressed into the flow bore. The novel adjusting has a transitional region on its circumference, between the at least one bead and an end segment oriented toward the valve closing body; at least one rounded portion is provided between the transitional region and the adjacent bead. Thus when the adjusting sleeve is pressed into the flow bore of the core, chip formation at the adjusting sleeve and flow bore is prevented. The adjusting sleeve is particularly suitable for injection valves of fuel injection systems of mixture-compressing internal combustion engines with externally supplied ignition.Type: GrantFiled: May 10, 1991Date of Patent: April 12, 1994Assignee: Robert Bosch GmbHInventors: Dieter Vogt, Ferdinand Reiter, Martin Maier

Patent number: 5295467Abstract: A known fuel distributor, which has continuous valve receptacle openings for fuel injection valves. The fuel distributor prevents vapor bubbles that cause difficulties in engine starting to form. The novel fuel distributor has a fuel supply line split by a partition into a first conduit and a second conduit; the second conduit serves as a reservoir and communicates both with the first conduit, through a through opening, and with the various valve receptacle openings. In the fuel reservoir, fuel free of vapor bubbles can collect after the shutoff of the hot engine; upon hot starting of the engine, this makes it possible to inject fuel that is free of vapor bubbles and is readily ignitable through the fuel injection valves. The fuel distributor according to the invention is especially well-suited for fuel injection systems of mixture-compressing internal combustion engines with externally supplied ignition.Type: GrantFiled: May 8, 1992Date of Patent: March 22, 1994Assignee: Robert Bosch GmbHInventor: Udo Hafner
