Abstract: The invention relates to a vapor seal member adapted to be received within the filler neck of a fuel tank. Normally, such filler necks are cylindrical in shape and sufficiently long to receive a corresponding discharge tube section of a fuel dispensing nozzle. The filler tube further includes a terminal rim at the outer edge to removably receive a closure cap. The vapor seal member includes a peripheral lip which firmly engages said terminal rim of said filler tube. A central resilient segment of the seal member defines an access opening adapted to slidably receive the discharge tube of the nozzle whereby to form an annular vapor tight seal with the latter and thus avoid passage of fuel vapors from the tank.

CPC classification number: B67D7/48
Abstract: An automatically operating fuel dispensing nozzle adapted to function within a sealed fuel system. In particular a signal system incorporated within said nozzle which functions to permit a topping-off operation for filling a fuel tank, or for automatically discontinuing a filling operation in response to an excessive pressure which might build up within the fuel tank or other parts of the closed system.

CPC classification number: B67D7/48 , Y10T137/7287
Abstract: An automatic tank filling nozzle involving a device responsive to the surge of fluid about the end of the nozzle for closing the main valve, having, in addition thereto, a flow-regulating valve normally in full-flow position but which is caused by the initial surge of fluid about the nozzle, to move to a secondary valve position where fluid flow is restricted to a relatively low rate suitable for ''''topping.'''' In the second or relatively restricted flow position of the flow-regulating valve the final rise of fluid about the nozzle acts to close off the main control valve.

CPC classification number: B67D7/48
Abstract: An automatic dispensing nozzle having means, in addition to the conventional vacuum responsive means for closing the main valve to reinstitute flow thru the nozzle at a relatively slow, predetermined rate suitable for carrying out the final or ''''topping-off'''' operation. With subsequent rise of fluid around the nozzle spout the resulting vacuum signal finally shuts off the operation. There is a predetermined time delay following initial closure of the main valve and prior to reinstitution of flow, sufficient to permit initial subsidence of fluid from about the spout of the nozzle.

CPC classification number: B67D7/48
Abstract: An automatic liquid dispensing nozzle wherein a lever, used to activate a control valve and regulate the rate of flow therethrough, is engaged by a holding means against the control valve, being released therefrom by automatic means upon the liquid being dispensed reaching a predetermined level, and subsequently being engaged by manual operation against a restraining member which permits the filling operation to be completed at a predetermined low rate of flow.

CPC classification number: B67D7/48 , Y10T137/7287
Abstract: An automatic fuel tank filling nozzle which, in addition to a main valve which automatically closes in response to a suction set up by the rise of fluid about the end of the nozzle, comprises a rotary flow-regulating valve having two alternate rotational positions, one permitting full flow of fuel thru the nozzle and the other permitting only a restricted flow suitable for topping, the rotary valve being rotated into the next alternate position in response to each vacuum signal whereas the main control valve is responsive only to the signal which follows the end of the topping operation.

CPC classification number: B67D7/48
Abstract: An automatic dispensing nozzle for liquid fuel of the type in which a main valve control lever is mounted on a fulcrum held in place by a quick release latch, responsive to a vacuum signal, wherein the latching device releases the fulcrum successively in two stages, in the first of which the main valve is closed to the point where flow is quite restricted, and in the final stage wherein the plunger is released to permit complete closure of the valve.
