  "abstract": "A pneumatic vacuum gripping assembly for attachment to a suction gripper device is coupled by way of a fluid flow link to a venturi for controlling the vacuum of the suction gripper device comprises an integrated housing assembly having a venturi and a pneumatic fluid-flow control valve unit. The valve unit controllably interrupts fluid communication between a main supply inlet port and the venturi and is controlled by the output of a pressure sensor that is integrated within the housing assembly. The assembly further includes a reset valve arranged in a compact, stack configuration with the other components of the valve unit and ported to the venturi vacuum line for controllably `blowing off` the suction gripper device from a gripped object.",
