Some historic examples of gravity feed systems include the Porsche 356 and early Volkswagens, which have a petcock with off, on, and reserve positions, much like a motorcycle petcock.
32.
An Argand lamp used whale oil, colza, olive oil or other vegetable oil as fuel which was supplied by a gravity feed from a reservoir mounted above the burner.
33.
He co-invented an automated loading system for nuclear fuel elements with a gravity feed conveyor, which permitted individual fuel pins to roll along a constrained path perpendicular to their respective lengths.
34.
There was a pump that brought the water to a holding tank on the third floor that sent water, via gravity feed, to main house's water tank to provide running water.
35.
The 21st and 22nd floors also contain a water tank which held reserve water for a gravity feed to the fire suppression system in case the city water main was breached.
36.
This enables the marker to have a higher rate of fire than a gravity feed without the addition of a battery operated loader ( at the cost of air efficiency ).
37.
This was intended to supply fuel to the engine by gravity feed in the event of an engine fuel pump failure; it contained enough fuel for thirty minutes on full power.
38.
Much of the foregoing applies equally to a gravity feed system; if vapor forms in the fuel line, its lower density reduces the pressure developed by the weight of the fuel.
39.
The Falcon was replaced by one of Rolls-Royce's new F . XI ( later known as the wing drag low, also allowing a gravity feed to the engine and reducing fire risks.
40.
Gravity Feed hoppers often get jammed up with balls at the feed neck, which can result in a marker'dry firing'( firing without paint ) or chopping balls due to the timing of the ball entering the marker.
