Patent ID: 6932101

Claim:
A gas supply control system comprising: a housing formed to define at least first, second, third, fourth, fifth, sixth, seventh, eighth, and ninth chambers, said first chamber communicating with a gas inlet, said fourth and ninth chambers respectively communicating with a pair of gas outlets; a solenoid valve assembly coupled said housing, said valve assembly including a first solenoid valve disposed in said second chamber for selectively controlling communication thereof with said fourth chamber, and a second solenoid valve disposed in said fifth chamber for selectively controlling communication thereof with said seventh chamber; and, a diaphragm assembly coupled to said housing, said diaphragm assembly including a first diaphragm disposed across said third chamber selectively engaging a partition between said first and fourth chambers for controlling communication therebetween, and a second diaphragm disposed across said sixth chamber selectively engaging a partition between said fourth and ninth chambers for controlling communication therebetween; said first diaphragm being deflectable responsive to said first solenoid valve opening communication between said second and fourth chambers; said second diaphragm being deflectable responsive to said second solenoid valve opening communication between said fifth and seventh chambers; whereby when a predetermined voltage is applied to said first solenoid valve, said first solenoid valve will be open thereby enabling gas to flow through said first, second, and fourth chambers and said gas outlets.
