Abstract

Claims (51)

1. A carburetor for a high performance vehicle, said carburetor including

a base plate,

first and second valve openings in said base plate for aligning with Venturi openings of a carburetor housing,

a first valve positioned in said first valve opening and a second valve positioned in said second valve opening,

a first valve linkage operatively connected to said first valve and a second valve linkage operatively connected to said second valve,

an actuator lever mounted to said first valve linkage for rotating said first valve linkage and said first valve,

a crank mounted to said second valve linkage for rotating said second valve linkage and said second valve,

a cam mounted to said actuator lever for engaging and moving said crank and rotating said second valve linkage and said second valve in response to the movement of the actuator lever, and

a quick disconnect coupling between said actuator lever and said cam such that the cam is removable from said actuator lever and can be replaced by another cam.

2. The carburetor of claim 1 , wherein

said first valve opening comprises a first pair of valve openings and second valve opening comprises a second pair of valve openings,

said first valve comprises a first pair of valves positioned in said first pair of valve openings, and said second valve comprises a second pair of valves positioned in said second pair of valve openings,

said first valve linkage operatively connected to said first pair of valves and said second valve linkage operatively connected to said second pair of valves,

such that movement of said actuator lever rotates said first pair of valves and said second pair of valves.

3. The carburetor of claim 1 , wherein said quick disconnect coupling comprises:

a lock pin that locks said tongue and said mounting shoe together.

4. The carburetor of claim 1 , wherein said quick disconnect coupling comprises:

said actuator lever includes a mounting shoe defining a recess,

said cam includes a tongue that mates with said recess of said mounting shoe,

a lock pin that extends through said mounting shoe and said tongue and locks said tongue and said mounting shoe together.

5. A carburetor for a high performance vehicle, said carburetor including

a first valve linkage for operative connection to a first pair of valves and a second valve linkage for operative connection to a second pair of valves,

an actuator lever mounted to said first valve linkage for rotating said first valve linkage and said first pair of valves,

a crank mounted to said second valve linkage for rotating said second valve linkage and said second pair of valves,

a cam mounted to said actuator lever for engaging and moving said crank and rotating said second valve linkage and said second pair of valves in response to the movement of the actuator lever, and

a quick disconnect coupling between said actuator lever and said cam such that the cam is removable from said actuator lever and can be replaced by another cam.

6. The carburetor of claim 5 , wherein said quick disconnect includes overlapping parts and a connector for holding the overlapping parts together.

7. The carburetor of claim 5 , wherein said quick disconnect includes

a shoe including a sidewall, a perimeter extending laterally from said sidewall and defining recess with said sided wall,

a tongue sized and shaped to register with said recess, and

a lock element engagable with said shoe and said tongue for locking said tongue to said shoe.

8. The carburetor of claim 7 , wherein

said lock element comprises a lock pin sized and shaped to be insertable through said perimeter and said tongue.

9. A carburetor for a high performance vehicle, said carburetor including

an actuator lever for rotating a first pair of carburetor valves in a base plate of a carburetor housing,

a crank for rotating a second pair of carburetor valves in the base plate of the carburetor housing,

a plurality of cams for mounting to said actuator lever for engaging and moving said crank and rotating said second pair of valves in response to the movement of the actuator lever,

each of said cams having closed cam tracks, with the closed cam track of each cam being of different configuration than the closed cam tracks of the other cams to actuate the second pair of carburetor valves at different degrees of movement of the actuator lever, and

a quick disconnect coupling between said actuator lever and said cam such that the cams are removable from said actuator lever and can be replaced by another cam.

10. The carburetor of claim 9 , wherein said quick disconnect includes overlapping parts and a connector for holding the overlapping parts together.

11. The carburetor of claim 9 , wherein said quick disconnect includes

a shoe including a sidewall, a perimeter extending laterally from said sidewall and defining recess with said sided wall,

a tongue sized and shaped to register with said recess, and

a lock element engagable with said shoe and said tongue for locking said tongue to said shoe.

12. The carburetor of claim 9 , wherein

said lock element comprises a lock pin sized and shaped to be insertable through said perimeter and said tongue.

13. A carburetor for a high performance vehicle including:

an actuator lever mounted to a first valve linkage for rotating a first pair of carburetor butterfly valves,

a crank mounted to a second valve linkage for rotating a second pair of carburetor butterfly valves,

a plurality of cams for interchangeably mounting on the actuator lever for engaging and moving said crank and rotating said second pair of valves in response to the movement of the actuator lever, said plurality of cams comprising cams having different shaped cam tracks for rotating the second pair of carburetor butterfly valves at different degrees of rotation of the actuator lever, and

a quick disconnect coupling between said actuator lever and said cam such that the cam is removable from said actuator lever and can be replaced by another cam.
