  • Patent number: 11951611
    Abstract: A vacuum device for a material handling system includes a vacuum device body and a sealing element. The vacuum device body has a vacuum passageway in which H vacuum is generated in response to activation of a pressurized air supply that forces pressurized air through a venturi device. The sealing element moves to a sealing position to substantially seal the vacuum passageway when the air supply is activated, and is urged toward the sealing position via pressurized air that is diverted from an inlet of the vacuum device to the sealing element. The sealing element moves to substantially vent the vacuum passageway when the air supply is deactivated. The vacuum passageway may be in fluid communication with a vacuum cup, which seals against the object when the sealing element is at the sealing position and the vacuum generating device generates at least a partial vacuum in the vacuum passageway.
