Pressure control valve for a fuel injection system provided with an accumulator

摘要

A pressure regulating valve for a reservoir-type fuel injection system for internal combustion engines serves to regulate the pressure in a fuel reservoir (common rail). The pressure regulating valve is designed in simplified form; the fuel reservoir is embodied as a closed reservoir and its supply and return lines are disposed inside a liquid level in such a way that without further action by the pressure regulating valve, it is not possible for the fuel reservoir to run empty.
