Patent number: 4915350Abstract: In known electromagnetically actuatable valves, a connecting tube connected to the armature has a valve closing element secured to its other end. The connecting tube has fuel flowing through it, which can exit again in the vicinity of the valve closing element via radially extending openings. To make such tubes additional work steps are required. There is proposed a novel connecting tube intended to assure easy manufacture and simple assembly with minimum weight and maximum stability. The novel connecting tube is provided with a slit extending from one end to the other, which provides the connecting tube with resilient elasticity and provides a large-area hydraulic cross section. The manufacture of the connecting tube can be accomplished easily by rolling of a sheet-metal blank. The embodiment of the connecting tube is suitable for electromagnetically actuatable valves of all kinds.Type: GrantFiled: August 23, 1989Date of Patent: April 10, 1990Assignee: Robert Bosch GmbHInventors: Rudolf Babitzka, Ferdinand Reiter

Patent number: 4916494Abstract: A monolithic integrated semiconductor device is described, wherein for the adjustment of the breakdown voltage a cover electrode (7) is disposed in the area of the pn-junctions and a corresponding potential is applied through a voltage divider (1) for adjusting the breakdown voltage. For maintaining a temperature independent breakdown voltage it is provided that the voltage divider (1) consists of resistors (R1, R2) in the form of diffused zones which have different doping levels. The resulting different temperature coefficients of the resistors (R1,R2) of the voltage divider cause a temperature dependent potential change of the cover electrode potential, whereby a temperature stabilization of the breakdown voltage is obtained.Type: GrantFiled: October 6, 1987Date of Patent: April 10, 1990Assignee: Robert Bosch GmbHInventors: Peter Flohrs, Hartmut Michel

Patent number: 4913115Abstract: When motor vehicles are driven, discontinuities that lead to load spikes arise between overrunning and running under load. The load spikes are avoided by means of a discontinuous increase in fuel quantity, which makes it possible for the engine to come gently to rest in its suspension, to bypass the drive play, and to convert the changes in increased fuel quantity without bucking. By incorporating drag elements into the connection between the arbitrary actuation of an intermediate lever, which affects the fuel injection quantity, and an idling stop, a discontinuous adjustment of the intermediate lever is attained.Type: GrantFiled: April 7, 1989Date of Patent: April 3, 1990Assignee: Robert Bosch GmbHInventors: Karl Konrath, Claus Koester, Manfred Schwarz, Klaus Krieger, Helmut Tschoeke, Ulrich Stratemeier

Patent number: 4912968Abstract: Motor vehicle components that function in accordance with the operating state of a fuel injection pump require a load signal from the pump that represents an accurate quantity relationship, so that they can function in a properly adapted manner. The accurate quantity relationship is attained in that initially, by mechanical means, two additional stops, temporarily lengthened by a spacer gauge, on the pump limit the rotation of an adjusting lever. The conversion into an electrical signal is effected via a potentiometer coupled to the adjusting lever, the characteristic curve of the potentiometer being effected in such a way, in a calibration process by means of laser trimming of two compensating resistors connected in series with the potentiometer, that the set-point voltages with which predetermined quantities are associated are attained at both stops. This reference voltage is suitable for triggering succeeding components of the fuel injection pump.Type: GrantFiled: March 22, 1989Date of Patent: April 3, 1990Assignee: Robert Bosch GmbHInventors: Heinz Northdurft, Karl-Friedrich Ruesseler, Wolfgang Braun, Wolfram von Huelsen
