Abstract
A metering device (30) for controlling the flow of fuel to a fuel pump includes metering valve means (36, 68), having a metering valve inlet (50; 150) and a metering valve outlet (68; 168), for controlling the rate of flow of fuel to the fuel pump, and regulator valve means (36, 62) operable to regulate the pressure of fuel at the metering valve inlet (50). A metering actuator (40) is operable to control the metering valve means (36, 68) and a regulator actuator (40) is operable to control the regulator valve means (36, 62). The metering actuator and the regulator actuator may be one and the same actuator, so that the metering and pressure regulating functions of the device are provided by a common valve member (36). In use, the valve member (36) co-operates with both the metering valve outlet (68; 168) and a pressure regulator valve outlet (62; 162) upon axial movement of the valve member (36) under the control of the actuator (40).
