<p>A magnetic valve arrangement for controlling flow of fluid, the magnetic valve arrangement having at least one ferromagnetic element (28, 42, 52) forming a portion of a magnetic circuit, a valve member (28, 50) and a valve seat (35); the valve member (28, 50) has a passage (31) therethrough for the flow of fluid and is moveable between a first position, in which the valve member (28, 50) abuts the valve seat (35) to restrict a fluid flow (26), and a second position, in which the valve member (28, 50) is spaced from the valve seat (35) to allow a fluid flow (26) into and through the passage (31) in the valve member (28, 50), wherein the position of the valve member (28, 50) is dependent on the temperature of the ferromagnetic element (28, 42, 52).</p> |
