  • Pneumatically operated airflow valve
    Patent number: 4221575
    Abstract: A novel, automatic, pneumatically operated bypass valve is provided in an r duct connecting a fan powered gas-particulate filter unit and an air conditioner unit. The bypass valve contains a bellows, which is automatically inflated by pressurized air transmitted thereto from the filter unit through a separate conduit, thereby closing the bypass valve when the filter unit fan is in operation. When the filter unit fan is turned off, the pressure in the filter unit falls to ambient, which automatically deflates the bellows and opens the bypass valve to provide a fresh air path to the air conditioner unit.
