  • Pressure regulating valve
    Patent number: 7721712
    Abstract: A pressure regulating valve in a fuel injection system for internal combustion engines for regulating the pressure in a fuel reservoir in which the operating pressure is adjusted by the dimensioning of an adjusting disk, whose function-determining axial height is ascertained with high precision by a force measuring system and by a travel measuring system by way of ascertaining a spacing between an end face of a valve member of the pressure regulating valve and a reference face of a housing of the pressure regulating valve.
