The integrated solenoid valve leads the air flow from the primary nozzle into the vacuum port. Together with the solenoid valve flow and air withdrawn from the exhaust an extremely fast blow-off is generated.
When the vacuum approaches atmospheric pressure, the blow-off is successively reduced and releases the work piece gently.The rapidness, small dimensions and low weight makes the ejector suitable for e.g. high speed robot applications.
The invention is patented by AVAC.
