FUEL TANK Russian patent published in 1994 - IPC

FIELD: automotive industry. SUBSTANCE: fuel tank has reservoir with fuel. Connected to hydrodynamic distributor arranged in reservoir and made up of body with spaces and diaphragm with double-acting valve at one side is suction pipeline and at two other sides- overflow pipe branches. Hydrodynamic distributor operates as follows; when one of overflow pipe parts gets exposed, air passes to body space, thus decreasing depression in space which causes displacement of diaphragm. Valve, moving, prevents passage of air from one space into another. Roughness of surfaces at place of contact of valve with body partition should be sufficient to provide gradual suction out of air from part of overflow pipe. As soon as depressions in spaces get equalized, valve will return to initial position. EFFECT: enlarged operating capabilities. 4 cl, 4 dwg
