Abstract: An elastic vacuum body of a vacuum gripper 10 for suctioning workpieces comprises a sealing lip 22 defining a vacuum chamber 26 at a side of the vacuum body 20 facing the workpiece. The vacuum chamber 26 is flow-connected to a vacuum supply and ribs 36, 38, 40 project into the vacuum chamber 26. The sealing lip 22 comprises at least one groove 28 on its surface 30 facing the vacuum chamber 26. The vacuum body can hold oily objects without slippage. Sheet metal is securely held without distorted bending.

Abstract: The present invention relates to an ejector for generating negative pressure having a pressure connection discharging into a propellant nozzle, and having a suction connection which discharges via a suction conduit into a receiver nozzle. The propellant nozzle and the receiver nozzle are provided in a suction valve with a first blocking piston for the propellant nozzle. A work conduit communicating with the pressure connection and a control conduit communicating with the pressure connection are provided and a blow conduit discharging via a blow valve into the suction connection communicates with a second blocking piston, and the piston position of the second blocking piston of the blow valve being triggerable via the control conduit.
