Filed:

Jan 30, 2007

Appl. No.:

11/699861

Inventors:

Kerry McLean - Milford MI, US

International Classification:

F16K 31/18

US Classification:

137420, 137410, 251 74

Abstract:

A mechanism for opening or closing a shut off valve, the mechanism having a lever mounted on a spindle to which the valve is attached for mounting the valve from a normally open position to a closed position. A trigger mechanism including the lever and a biasing spring which when activated, rotates the lever, spindle and valve. A retainer mechanism ordinarily holds the trigger mechanism in a cocked position corresponding to the open position of the valve. The float, when subjected to water, releases the retainer mechanism permitting the trigger mechanism to close the valve.

6/319636

Inventors:

Kerry L. McLean - Southfield MI

International Classification:

F02M 2102

US Classification:

123527

Abstract:

A gaseous fuel-air mixture device for an internal combustion engine having an intake for a fuel-air mixture. A chamber for mixing gaseous fuel and air is provided above the intake. The gaseous fuel is uniformly injected into the mixture chamber from an aperture in the chamber wall. The quantity of air mixed with the gaseous fuel in the mixture chamber is controlled by adjusting the height of a control plate disposed above the chamber.

Kerry L. McLean - Southfield MI

International Classification:

F02M 1306

US Classification:

123527

Abstract:

An internal combustion engine dual fuel system for controllably running the internal combustion engine on a liquid fuel, such as gasoline, in the usual manner or, at will, on liquified petroleum (LP) gaseous fuel. The conventional liquid fuel system of the internal combustion engine is unmodified except for the addition of a remotely controlled shut-off valve in the fuel line at the carburetor fuel inlet. An LP gas suction verturi is disposed in the air induction flow to the carburetor inlet, for example by being mounted in the air filter above the carburetor inlet, and is supplied in fuel from the vapor phase of an LP gas, such as butane or propane, above the level of the liquified gas in an appropriate tank. The LP gas tank and the line supplying the gas to the carburetor air inlet are maintained at a substantially constant temperature via a by-pass of the engine coolant circuit, the flow of coolant through the by-pass being automatically controlled by a thermostat. A manual control, in the form of an electrical switch, is provided for shutting off the flow of LP gas while running the engine on conventional liquid fuel, and shutting off the flow of liquid fuel to the carburetor while running the engine on LP gas.
