Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
175 words
In combination with an internal combustion engine having a carburetor, an apparatus for injecting fluid into said carburetor, said apparatus comprising: plate means connected to the carburetor of an internal combustion engine; a pump for providing a flow of pressurized air; conduit means secured to the plate means for providing a flow of fluid and pressurized air to the plate means; a first intake line secured to the conduit means and to the pump for providing a flow of pressurized air to the conduit means; a second intake line secured to the conduit means and disposed directly above the first intake line for providing a flow of fluid to the conduit means; a mixer chamber in the conduit means at the juncture of the first and second intake lines and spaced apart from the plate means for mixing the flow of pressurized air and the flow of fluid together; and an opening at the juncture of the conduit means and the plate means through which the flow of fluid and air flows into the carburetor.
