Abstract
A venturi valve assembly, having a flow tube, an upper port integrally formed with flow tube, a flow cavity disposed within the flow tube, an inlet formed as part of the flow tube such that the inlet forms a part of the flow cavity, an outlet formed as part of the flow tube such that the outlet forms a part of the flow cavity, and a venturi nozzle disposed in the flow tube. Pressurized air flows into the flow cavity from the inlet such that the pressurized air flows around the venturi nozzle. Purge vapor flows into the flow cavity from the upper port, and the flow rate of the pressurized air is increased after flowing around the venturi nozzle, increasing the flow of the purge vapor after the purge vapor is mixed with the pressurized air in the flow tube.
