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