Patent number: 4767288Abstract: A fuel injection pump is proposed in which the fuel supply quantity supplied to the injection location is determined by metering the quantity of fuel aspirated. The metering of the aspirated quantities is effected with the aid of at least one magnetic valve which is located in the fuel supply line leading to the fuel injection pump and with the aid of a control edge moved in synchronism with the rotation of the fuel injection pump, which controls the communication between the fuel supply line and the pump work chamber in series with the magnetic valve. The opening times of the two control locations are each longer than the maximum metering time, the overlapping time of the two control times determining the opening time of the communication between the fuel supply and the pump work chamber. The metering time is thus determined on the one hand by the switching time of the control edge moved in synchronism with the rpm and the other by a switching process of the magnetic valve.Type: GrantFiled: May 21, 1982Date of Patent: August 30, 1988Assignee: Robert Bosch GmbHInventor: Max Straubel

Patent number: 4765693Abstract: A valve assembly for an anti-skid brake system has at least two valves disposed parallel to one another. Both valves are embodied in the manner of check valves having closing springs. To open the valves, there is an armature displaceable by an electromagnet; the armature opens the first valve automatically via a rigid opening tappet and opens the second valve, via another opening tappet and a spring associated with it, only when a pressure urging the second valve in the closing direction does not exceed a preselected pressure difference relative to an armature chamber. This has the advantage that despite the high pressure drop, the quantity of pressure fluid per unit of time that flows through the valve assembly does not exceed a preselected threashold value in the anti-skid regulation situation; on the other hand, without anti-skid operation, a rapid buildup of brake pressure is possible by furnishing a larger flow cross section.Type: GrantFiled: January 21, 1987Date of Patent: August 23, 1988Assignee: Robert Bosch GmbHInventor: Alwin Stegmaier

Patent number: 4764048Abstract: A lightweight ball-and-socket joint that is for instance capable of being assembled by a robot. The ball-and-socket joint has a ball head, a CIRCLIP and an outer structural part forming a socket, in which there is a circumferential groove the bottom of which forms a support face for the circlip. The support face is substantially defined by a hollow cone and surrounds the CIRCLIP like a jacket, and a flare angle of the support face opens toward the center of the ball head. The CIRCLIP presses with radial bias against the support face and therefore migrates in the direction of its largest diameter and hence toward the center of the ball head until it rests thereon.Type: GrantFiled: December 29, 1986Date of Patent: August 16, 1988Assignee: Robert Bosch GmbHInventors: Georg Kehl, Ernst-Dieter Schafer
