Title: Cutoff valve device for liquid
Inventor: MIZUMACHI SHOJI
IPC: B60K15/077
Filed: 1997-03-25
Abstract: PROBLEM TO BE SOLVED: To achieve a large flow of exhaust gas and prevent fuel from leaking during overturning, by equipping relief rod which transmits valve opening action of a relief valve to a float valve. SOLUTION: When pressure in a fuel tank 101 is more than valve-opening setting pressure of a relief valve VR, a valve element 3a opens downward. By releasing pressure of the fuel tank 101 to an exhaust chamber 2d through a gap between a valve sheet 7a and the valve element 3a, and pressing the valve element 3a of a float valve VF with a relief rod 8b, 'sticking phenomenon' is eliminated. During overturning, energization force which is caused by pressure of a fuel L impressed on the float valve VF and directs in the closing direction of the float valve VF, and energization force which is caused by pressure of fuel L entering into a pressure passage and directs in the opening direction of the relief valve VR are balanced with the relief rod 8b, and therefore valve opening pressure of the relief valve VR is increased.  Thus, by enlarging diameter of the float valve VF, large amount of exhaust gas flows and fuel is prevented from leaking from the relief valve.
