Abstract
A pneumatically-operated gas demand apparatus coupled in interruptible fluid communication between a recipient and a first source of a pressurized first gas controls delivery of the first gas to the recipient and comprises a supply valve and a sensing valve. The supply valve has a first interior chamber divided by a flexible first diaphragm into supply and control chamber regions.
The sensing valve has a second interior chamber divided by a flexible second diaphragm into venting and sensing chamber regions. When the recipient inhales, the second diaphragm moves to cause a second gas to flow into the environment and causes the first diaphragm to move to deliver the first gas to the recipient. When the recipient exhales, the second diaphragm moves to prevent the second gas to flow into the environment and causes the first diaphragm to move to prevent delivery of the first gas to the recipient.
The sensing valve has a second interior chamber divided by a flexible second diaphragm into venting and sensing chamber regions. When the recipient inhales, the second diaphragm moves to cause a second gas to flow into the environment and causes the first diaphragm to move to deliver the first gas to the recipient. When the recipient exhales, the second diaphragm moves to prevent the second gas to flow into the environment and causes the first diaphragm to move to prevent delivery of the first gas to the recipient.
