Abstract
A vent device is provided for common venting of exhaust gases discharged from separate apparatus at different vent pressures. The vent device provides a passageway and exhaust gas inlets for combining the exhaust gases and conveying them to a single vent stack. The higher vent pressure exhaust gases are discharged within the passageway using a venturi or jet pump effect to provide a zone of reduced pressure in the passageway for inducing the flow of the lower vent pressure exhaust gases into the device.
