    摘要: An apparatus for determining the status of a shut-off valve arrangement (28) forming part of a fuelling system of an engine comprises a metering valve arrangement (24) comprising a metering valve member (32) for regulating fuel flow from a pump (16) forming part of the fuelling system to the engine and means (46) for monitoring the position of the metering valve member (32). The shut-off valve arrangement (28) is operable between open and closed positions and the metering valve arrangement (24) is operable between a maximum flow position, in which the flow of fuel through the metering valve arrangement (24) to the shut-off valve arrangement (28) is a maximum, and a minimum flow position in which the flow of fuel through the metering valve arrangement (24) to the shut-off valve arrangement (28) is a minimum. The position of the metering valve member (32) is controlled by controlling fuel pressure acting on the metering valve member (32). The apparatus futher comprises means (61,63) for varying fuel pressure acting on the metering valve member (32) upon closure of the shut-off valve arrangement (28), and means (46,43) for monitoring the response of the metering valve arrangement to the variation in fuel pressure applied to the metering valve member (32) so as to provide an indication that the shut-off valve arrangement (28) has closed.

    摘要: A fuel control system for a combustion engine, the system being characterised by comprising:

    an electrically driven centrifugal pump (220; 429; 620) operable at a pump speed, wherein the pump is arranged to supply pressurised fuel to the engine, and
    a pressure raising valve (224; 424; 524; 624) for ensuring the pressure of fuel within the fuel control system is maintained above a predetermined, minimum amount, wherein the pressure raising valve is adapted to provide a substantially linear variation of fuel flow rate to the engine with pump speed.

    There is also disclosed a pressure raising valve for use in such a system.

    摘要: A control system is provided for use in controlling fuel supply to at least two sets of burners (18, 22, 26, 28) of an engine. The control system comprises two or more fuel pumps (12a, 12b), each of the pumps (12a, 12b) being driven, in use, by a respective variable-speed motor (14a, 14b). Control means (30) is provided for controlling the speed of the motors so as to regulate the rate of flow of fuel to each of the sets of burners (18, 22, 26, 28).
