A magnetic valve arrangement for controlling flow of fluid, the magnetic valve arrangement having at least one ferromagnetic element forming a portion of a magnetic circuit, a valve member and a valve seat; the valve member has a passage therethrough for the flow of fluid and is moveable between a first position, in which the valve member abuts the valve seat to restrict a fluid flow, and a second position, in which the valve member is spaced from the valve seat to allow a fluid flow into and through the passage in the valve member, wherein the position of the valve member is dependent on the temperature of the ferromagnetic element.

1. A magnetic valve arrangement for controlling flow of fluid, the magnetic valve arrangement comprising: at least one ferromagnetic element forming a portion of a magnetic circuit;a valve member; anda valve seat, wherein the valve member is disposed substantially fluid conduit,the valve member has a passage therethrough configured to allow passage of a flow of fluid,the valve member is moveable between a first position, in which the valve member abuts the valve seat to restrict the flow of fluid, and a second position, in which the valve member is spaced from the valve seat to allow the flow of fluid into and through the passage in the valve member,whether the valve member is in the first position or the second position depends on a temperature of the at least one ferromagnetic element, andthe valve member comprises a tube. 2. The magnetic valve arrangement as claimed in claim 1, wherein at least a portion of the valve member comprises a part of the magnetic circuit. 3. The magnetic valve arrangement as claimed in claim 1, wherein at least a portion of the valve member comprises the at least one ferromagnetic element. 4. The magnetic valve arrangement as claimed in claim 1, wherein a magnet selected from the group consisting of a permanent magnet and an electromagnet forms a portion of the magnetic circuit. 5. The magnetic valve arrangement as claimed in claim 4, wherein the magnet is coaxial with the valve member. 6. The magnetic valve arrangement as claimed in claim 1, wherein the valve member has an axis of symmetry perpendicular to a direction of fluid flow in the fluid conduit. 7. The magnetic valve arrangement as claimed in claim 1, further comprising: a sealing means. 8. The magnetic valve arrangement as claimed in claim 7, wherein the sealing means is selected from the group consisting of a sliding seal between the tube and a wall of the fluid conduit, and at least one poppet valve seal. 9. The magnetic valve arrangement as claimed in claim 1, further comprising: at least one locating feature selected from the group consisting of a leaf spring and a Belleville washer. 10. The magnetic valve arrangement as claimed in claim 1, wherein the at least one ferromagnetic element is thermally coupled to one of the flow of fluid in the fluid conduit, a second flow of fluid, and a component of a gas turbine engine. 11. The magnetic valve arrangement as claimed in claim 10, wherein the at least one ferromagnetic element is thermally coupled by means of at least one duct to deliver the fluid to the at least one ferromagnetic element. 12. A gas turbine engine including the magnetic valve arrangement as claimed in claim 1, wherein the at least one ferromagnetic element is thermally coupled to a component of the gas turbine engine. 13. The magnetic valve arrangement as claimed in claim 1, wherein the flow of fluid in the fluid conduit is directed to one of the group consisting of a component of a gas turbine engine and a re-entrance of the fluid conduit. 14. The magnetic valve arrangement as claimed in claim 1, wherein the fluid conduit is substantially restricted when the at least one ferromagnetic element is above or near Curie temperature of the at least one ferromagnetic element. 15. A gas turbine engine including the magnetic valve arrangement as claimed in claim 1, wherein a component of the gas turbine engine is thermally coupled to the flow of fluid.
