Rapid closing valve for fuel storage tank - moves from fully open to shut at pre-determined fuel level

Abstract

Abstract A valve plate (7) is normally in the open position and attached to a spindle (5) which projects through the housing (1) to engage the arms of a stirrup (12) carrying counterweights (11). The stirrup (12) has a pin (13) which normally fits in the notch in the cam (15a) forming part of the lever (15) which pivots on the pin (16). When the fuel reaches the pre-determined level, the float (18) rises and causes the lever (19) to rotate about the pivot (17) so that the pin (22) rotates the lever (15) freeing the pin (13) and pushing the stirrup (12) upwards to bring the valve plate (7) down on to the valve seat (3).
