<p>A shut down mechanism which in one aspect is suitable for shutting down a fuel supply line of an apparatus, the mechanism comprising a releasable lock which is movable between a lock position in which position the fuel supply line is in an operating mode and a release position in which position the fuel supply line is in a shut down mode. The mechanism further includes a lock activating device activation of which is caused by manual activation or activation as a result of abnormal operating conditions of the apparatus. The shut down mechanism further includes a reservoir an interior which, in use, is at a lower pressure relative to a normal operating pressure of the fuel line. The reservoir includes an inlet which is in fluid communication with a downstream end of the fuel line when the lock is in the shut down mode enabling fuel in the downstream end of the fuel line to pass into the reservoir. Other aspects of the invention are concerned with shut down mechanisms for shutting down an electric circuit or other energy supply system.</p> |
