Gentlemen,

Many automobiles manufacturers are using a vacuum feed instead of a pressure or gravity system and you know of course, that if it is true that these devices have some advantages, it is also true that a big trouble happens, when the suction in the intake manifold is not enough to carry the petrol up to the level of the vacuum feed.

I just bought lately a patent of a "nipple" which is very simple and very cheap and which permits to double automatically the suction just when it is decreasing.

This device is only a "nipple" to be put between the intake manifold of the motor and the suction line to the vacuum feed system.

It can be made very easely and can be connected to any type of vacuum feed device having a very low chamber. The patent for which it has been applied lately, has a basic point in a knew and very simple fisical principle and avoids all chances of imitation.

Are you interested buying the right to manufacture yourselves these nipples for your automobiles? or do you prefer to buy them from me?

I will be obliged if you will let me know your opinion on this matter.

yours truly,
ALBERTO CHIESA

EB/SC. I enclose a description and drawing of the nipple.
