FUEL FILLING COLUMN Russian patent published in 1998 - IPC

FIELD: road transport; dispesing of fuels. SUBSTANCE: invention relates to fuel dispensing systems and is designed for condensing of gasoline fumes formed when gasoline passes through fuel filling column. Fuel filling column has series-connected intake valve, filter, pump, gas separator, fuel flow rate reducing valves and cutoff valve and fuel meter. Fuel filling column has ultrasonic diaphragm device in form of cylinder made of organic glass and provided with longitudinal capillaries and channels connecting the capillaries and located square to longitudinal capillaries near upper base of cylinder along its radii. Fuel filling column has also ultrasonic radiator connected with ultrasonic generator, tube plate to absorb ultrasonic oscillations secured on lower base of cylinder, and ring seals arranged between inner surface of outlet branch pipe and side surface of cylinder of diaphragm device. One of seals is arranged close to upper base of cylinder, and the other, lower than channels located close to upper base. Drawout branch pipe is connected to outlet branch pipe in space between ring seals. Pump of fuel filling column is connected with motor, and fuel meter is connected to cutoff device. To enhance cooling of gasoline fumes, inlet pipeline is closed at end faces, is provided with holes arranged below fuel level, is covered with gauze or cloth and extends to bottom of float chamber. Float chamber with ultrasonic diaphragm device is covered by heat insulating material. EFFECT: more complete utilization of fuel fumes. 2 cl, 6 dwg
