VALVE

摘要

A cut-off valve for stopping flow of a fluid comprises a valve body in which is defined a fuel flow passage (12) between an inlet (2) and an outlet (4). A valve member (6), which is of paramagnetic material is moveable along the passage between a first position (121) allowing fluid to flow from the inlet to the outlet, and a second position (122) in which the valve member blocks the outlet to stop flow of fluid. First magnetic means (10) are provided for holding the valve member in the first position, and second magnetic means (8) are provided for holding the valve member in the second position.
