FIELD: machine building.SUBSTANCE: invention relates to production of shutoff valves and accessories. Fuel tank valve comprises the body composed by float chamber and disc chamber communicated via intermediate flow channel. Float chamber is composed of the valve inlet bores communicated with said fuel tank and fluid inlet to intermediate flow channel. Disc chamber is composed by fluid discharge outlet from said intermediate flow channel and the valve discharge opening. Fluid inlet is stopped by the float shutoff element displacing axially in said float chamber. Fluid discharge outlet is stopped by the float shutoff element to maintain the pressure displacing axially in the disc chamber. Said pressure maintenance element is composed of rarefaction compensation valve displacing between shutoff compensation valve position whereat it is closed and position "Open" whereat it is opened to allow fluid flow there through.EFFECT: higher reliability in operation.20 cl, 16 dwg |
