Vacuum Control Valve

The vacuum control valve is attached to the injection pump and connected to the adjusting lever by means of a driver. With supply vacuum connected (central connection), the valve modulates under increasing load with a drop in pressure. This modulated pressure is processed still further by a pressure converter.
