Abstract
Abstract Apparatus and method for use associated with an internal combustion engine whereby drainage of fuel, vapor and oil drainage from the crankcase thereof is recovered and introduced in a metered fashion into the principal fuel line of the engine. A dual-chambered device is employed having an upper chamber connected to the crankcase for accumulating drainage, and a lower chamber serving as a mixing chamber connected in series with the principal fuel line. At the top of the mixing chamber there is mounted a diffuser plate for receiving and dispersing the drainage as it falls from a valve assembly in the drainage chamber directly above. The diffuser plate acts to disperse the drainage in a thin film over the surface of the plate after which the drainage falls off the sides of the plate and mixes readily with the fuel from the principal fuel supply in the mixing chamber. Also provided across the top of the diffuser plate is a channel which acts as a baffle to enhance the mixing action of the drainage with the fuel.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
160 words
In a device for distributing drainage and the condensed vapor thereof from the induction system of an internal combustion engine to the fuel mixture delivered by a fuel system to the engine, said device including a mixing chamber having an inlet and an outlet passage, said mixing chamber being adapted to be connected in series with the fuel system, a drainage chamber adapted to receive drainage from the engine, means providing passage for drainage from said drainage chamber to the upper portion of said mixing chamber, the improvement of which comprises diffuser plate means located directly below said drainage passage means at a fixed elevation in the upper end of said mixing chamber, said diffuser plate means having an upper surface for receiving the drainage flowing from said passage means and dispersing said drainage in a thin film which descends from the periphery of the diffuser plate means, whereby said drainage mixes readily with the fuel in said mixing chamber.
Claim 2
Dependent Claim
160 words
In a device for distributing drainage and the condensed vapor thereof from the induction system of an internal combustion engine to the fuel mixture delivered by a fuel system to the engine, said device including a mixing chamber having an inlet and an outlet passage, said mixing chamber being adapted to be connected in series with the fuel system, a drainage chamber adapted to receive drainage from the engine, means providing passage for drainage from said drainage chamber to the upper portion of said mixing chamber, the improvement of which comprises diffuser plate means located directly below said drainage passage means at a fixed elevation in the upper end of said mixing chamber, said diffuser plate means having an upper surface for receiving the drainage flowing from said passage means and dispersing said drainage in a thin film which descends from the periphery of the diffuser plate means, whereby said drainage mixes readily with the fuel in said mixing chamber.
Claim 3
Dependent Claim
46 words
A device as recited in claim 1 wherein said upper surface of said diffuser plate means extends in a substantially horizontal direction throughout the interior of the mixing chamber with said periphery of the diffuser plate means being spaced from the walls of the mixing chamber.
Claim 4
Dependent Claim
69 words
A device as recited in claim 2, wherein said diffuser plate means comprises a generally disc-shaped plate having a longitudinal channel which is raised above the surface of said plate and extends across the diameter of said plate, whereby the drainage flowing from said passage means falls on to the top surface of said channel after which it disperses in a thin film over the top of said plate.
Claim 5
Dependent Claim
32 words
A device as recited in claim 3, wherein said diffuser plate means is mounted near the top of said mixing chamber at substantially the same level set by a fuel level valve.
Claim 6
Dependent Claim
66 words
A device as recited in claim 4 wherein said device has a partition wall directly above said diffuser plate means for separating said drainage chamber from said mixing chamber, said means providing passage for drainage including at least two valves mounted in said partition wall through which said drainage flows to said upper surface of said diffuser plate means, said valves being spaced from each other.
Claim 7
Dependent Claim
48 words
A device as recited in claim 5 wherein said diffuser plate means includes a plate on which the drainage is dispersed in a thin film, and a baffle for the fuel in the mixing chamber, said baffle including a longitudinal channel extending along the top of said plate.
Claim 8
Dependent Claim
46 words
A device as recited in claim 6, wherein said diffuser plate means is positioned near the top of said mixing chamber by an extension means securely mounted to the inside wall of said mixing chamber, with the longitudinal channel resting on top of said extension means.
Claim 9
Dependent Claim
67 words
A device as recited in claim 2, further comprising valve means associated with said passage means for blocking said passage means upon there being less than a predetermined level of drainage in said drainage chamber and allowing the flow of drainage from said drainage chamber to said mixing chamber through said passage means upon there being more than a predetermined level of flow in said drainage chamber.
Claim 10
Dependent Claim
29 words
A device as recited in claim 8 wherein said valve means includes a check valve for preventing the backup of fuel from said mixing chamber into said drainage chamber.
