Abstract
Abstract The present apparatus has different combined elements depending on the pressure differential developed between a tube positioned in an air intake manifold system for a compression engine and the ambient atmosphere. If the pressure differential is adequate to provide fluid flow through the fluid reservoir into the air manifold, a regulator member is positioned with the container to control the fluid flow. If the pressure differential is not adequate to provide fluid flow through the fluid reservoir into the air manifold, a flow tube connected with the container is positioned in the air manifold to develop sufficient pressure differential. If the air manifold pressure is greater than that of the ambient atmosphere, an impact tube connected with the container is placed upstream of the flow tube to develop adequate pressure differential by forcing air into the fluid container. Additionally, a check valve may be positioned with the container to prevent fluid flow from the air manifold to the fluid container. Finally, a needle valve may be positioned with the container to constantly regulate the fluid flow from the fluid reservoir to the engine air manifold.

Claim 1
Independent Claim
263 words
An injector apparatus for use in injecting fluid in an air manifold tube air passageway of an engine comprising: a. a fluid flow tube means positioned in the air passageway, said tube means having a plurality of holes therein positioned substantially in transverse relation relative to the flow of air through the air passageway; b. said fluid flow tube means being positioned in the air passageway such that a vacuum is created to remove vapor or fluids from said holes in said fluid flow tube means into the air passageway; c. container means for housing the fluids; d. a first flexible tube means connected at one end with said fluid flow tube means and said container wherein the vacuum removes vapor or fluids from said container through said first flexible tube means and into said fluid flow tube means and out through said holes therein into the air passageway; e. air impact tube means positioned in front of said fluid flow tube means, said air impact tube means having holes therein for enabling air to flow into said air impact tube means; and f. a second flexible tube means mounted at one end with said air impact tube means and extending downwardly into said container and the fluid therein wherein air moves into said impact tube means and through said second flexible tube means and out through the end of said second flexible tube means to vaporize fluid positioned in said container to increase the pressure in said container for enabling vaporized fluids to be removed therEfrom through said first flexible tube means.
