Gravity feed ball-in-seat valve with extension unit for dosing fuel additives
First Claim
1. A simple, reliable system for automatically dosing fuel tanks with a fuel additive, particularly a concentrate containing a fuel borne catalyst (FBC) using gravity as the means of injection and is operable by insertion of a filler hose into the filler spout of a fuel tank, comprising:
- a supply line for feeding fuel additive by gravity from an additive reservoir and opening into a filler spout of a fuel tank;
a ball-in-seat valve at the end of the supply line biased in normally closed position and operable to an open position by mechanically pressing a release on the ball-in-seat valve;
a pivotable lever positioned within the filler spout and including a projection capable of mating with the ball-in-seat valve release upon pivotable movement, wherein the pivotable lever is configured to move from an initial position wherein it interferes with the insertion of a filler hose into the filler spout but movable by the spout by the insertion of a filler hose to a position wherein the projection presses the release on the ball-in-seat valve.

Abstract
A simple, reliable system is provided for automatically dosing vehicle fuel tanks with a fuel additive, particularly a concentrate containing a fuel borne catalyst (FBC), using gravity as the means of injection, preferably with no electronics or complex mechanical parts. The system includes a supply line for feeding fuel additive by gravity from an additive reservoir and opening into a filler spout of a fuel tank, a ball-in-seat valve at the end of the supply line biased in normally closed position and operable to an open position by mechanically pressing a release on the ball-in-seat valve, and a pivotable lever positioned within the filler spout and including a projection capable of mating with the ball-in-seat valve release upon pivotable movement. Upon insertion of a filler hose into the filler spout, the filler hose moves the lever and projection to press the release on the ball-in-seat valve thereby dispensing additive.

- 4. A mechanical ball-in-seat valve liquid dispensing system for the addition of fuel additives into a fuel tank containing gasoline, diesel or alternative fuels used to power an internal combustion engine, wherein such ball-in-seat valve is opened to dispense additive into the fuel tank by the inserting of a fuel delivery nozzle into the fuel fill spout of a fuel tank and said valve is closed by removing the fuel nozzle.
