Definitions
- the invention relates to a pressure regulating valve according to the preamble of claim 1.
- High-pressure accumulator (Common Rail) is the fuel system pressure in
- High-pressure accumulator held substantially constant by means of a pressure control valve. As soon as the pressure in the high-pressure accumulator exceeds the system pressure, the pressure regulating valve opens, when the pressure has fallen below the system pressure, the pressure regulating valve closes. This ensures that the fuel injection into the cylinders of the internal combustion engine takes place under constant conditions. The fuel pressure drops in the
- High-pressure accumulator under the vapor pressure of the air dissolved in the fuel, the air is exhausted, so that in addition to the liquid fuel and a gas phase in the high-pressure accumulator is included.
- the gas contained in the high-pressure accumulator must be through the
- High-pressure pump are compressed so that builds up in the high-pressure accumulator necessary for the operation pressure. Depending on the starting temperature of the internal combustion engine this several engine revolutions are necessary, causing startup delays occur. To a gassing of the
- a pressure control valve in which at standstill of the internal combustion engine, the pressure regulating valve is open, that is, in that a connection from the high-pressure accumulator to a low-pressure line is released by a closing element.
- the pressure regulating valve has a magnetic actuator, which is energized to close the closing element by an armature, the closing element in a valve seat.
- Closing element is a spring element provided that against the
- Magnetic force of the magnetic actuator acts and thereby moves the armature and an anchor bolt attached thereto in the opening direction, whereby the
- Closing element lifts off the valve seat and a hydraulic
