Abstract
A gas/air mixer assembly provides a Venturi metering system that may draw fuel from a zero governor, mix it with air to form a homogenous gas/air mixture for delivery to an internal combustion engine. The gas/air mixer assembly may also accept fuel under pressure from a gas metering valve or fuel injector for delivery to an internal combustion engine. The mixer includes an air horn, the relative position of which in relation to a shaped restriction body governs the air flow into the engine intake manifold. The flange of the air horn is configured to redirect the flow of air without generating significant turbulence, and providing a maximum velocity perpendicular flow to the injection of fuel to be mixed therein. The relative position of the air horn to the shaped restriction body is determined based on the cubic capacity and speed of the engine with which it is used.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
