Abstract
A vacuum cup assembly has a vacuum device with a vacuum passageway and a venturi. A vacuum cup is configured to engage an object. The venturi generates an at least partial vacuum at the vacuum cup when the vacuum cup is engaged with an object. The vacuum cup seals against the object when the venturi device generates the at least partial vacuum. A noise reducing device is at a discharge of the venturi. The noise reducing device has a housing defining a chamber, a plurality of spaced exit openings and a movable cap. Air discharged at the venturi is diverted in the chamber and flows out through the exit openings. The movable cap covers the exit opening to override the vacuum to enable the vacuum cup to be positioned or repositioned on the object.
