Abstract
An arrangement for controlling flow of fluid to a component of a gas turbine engine, the arrangement comprising: a conduit, coupled to a supply of fluid, for providing fluid to the component of the gas turbine engine; a magnetic valve for at least partially restricting the conduit and having a valve member with at least a first configuration in which the conduit is at least partially restricted and a second configuration in which the conduit is relatively open, wherein the configuration of the valve member is controlled by magnetic flux in a magnetic circuit which includes at least one member comprising ferromagnetic material, whereby the configuration is responsive to the temperature of the ferromagnetic material.
