Patent ID: 8042569

Claim:
A fuel selector valve in communication with at least first and second fuel tanks and an engine, the fuel selector valve comprising: (a) a motor drive system configured to provide rotary movement; (b) a fuel draw valve coupled to the motor drive system, the fuel draw valve comprising: (i) a first fuel tank draw port adapted to be coupled to the first fuel tank and a second fuel tank draw port adapted to be coupled to the second fuel tank; (ii) an engine draw port adapted to be coupled to the engine; (iii) a first ball valve closure element operably coupled to the motor drive system, the first ball valve closure element being selectively rotatably displaceable between a first position, wherein the first ball valve closure element sealingly engages the first fuel tank draw port, a second position, wherein the first ball valve closure element sealingly engages the second fuel tank draw port, and a third position in which the first and second fuel tank draw ports remain open; and (iv) a cam assembly for biasing the first ball valve closure element into the first or second position based on a rotational position of the first ball valve closure element and in a manner such that the first ball valve closure element cannot physically come into substantial contact with the first or second fuel tank draw port when being moved into the first or second position.
