Patent ID: 7318426

Claim:
A fuel-control manifold, comprising: a non-integral body comprising at least three pieces joined together and including an upper body segment, a middle body segment, and a lower body segment; a tank port in the upper body segment; an engine supply port in the upper body segment; a fueling port in the upper body segment; a shutoff valve in the upper body segment, the shutoff valve including a controllable shutoff valve closure having a shutoff-valve first side in fluid flow communication with the tank port and a shutoff-valve second side in fluid flow communication with the engine supply port and with the fueling port; a defueling port in the lower body segment; a vent port in the upper body segment; and a defuel/vent valve in the middle body segment, the defuel/vent valve comprising a controllable ball-valve defueling closure having a defueling-valve first side in fluid-flow communication with the shutoff-valve second side and a defueling-valve second side in fluid-flow communication with the defueling port, and a controllable ball-valve vent closure having a vent-valve first side in fluid-flow communication with the vent port, and a vent-valve second side in fluid-flow communication with the defueling-valve second side, wherein the defuel/vent valve has no elastomeric materials therein, wherein the defueling closure and the vent closure are mounted on a common defuel/vent valve stem, and wherein the defueling closure and the vent closure cannot be open at the same time.
