  • Publication number: 20250129803
    Abstract: A vacuum production device includes at least a first ejector having an inlet port and a suction port. The device includes a control member that includes a body having at least one pressure inlet and one suction inlet intended to be connected respectively to a pressurised air circuit and to a vacuum circuit, and a first spool mounted so as to be able to move in the body between a connection position in which the inlet port of the first ejector is connected to the pressure inlet and the suction port of the first ejector is connected to the suction inlet, and a disconnection position in which the inlet port of the first ejector is disconnected from the pressure inlet and the suction port of the first ejector is disconnected from the suction inlet. A handling device includes such a vacuum production device.

  • Publication number: 20250033226
    Abstract: A grip member for a vacuum box includes a tubular body having a first section delimiting a cavity in which a hollow piston is slidingly mounted, a first chamber of variable volume, into which a compressed air conduit opens, the piston being provided with a tubular extension having a free end section projecting from the first cavity and provided with a suction cup, the piston and the tubular extension defining a suction channel having an end which opens into the suction cup and an opposite end which slidingly, sealingly receives a rod, the tubular extension including a suction orifice to connect the suction channel to a second chamber under negative pressure, and the piston being movably mounted in translation with respect to the rod between a rest position in which the rod blocks the suction orifice and a gripping position in which the rod is recessed from the suction orifice.

  • Patent number: 11680586
    Abstract: A Venturi type ejector having a feed duct for feeding fluid under pressure with the duct extending along a central axis. A first expansion chamber is connected to the feed duct; a first mixing chamber is connected to the expansion chamber; a first suction chamber is connected to the mixing chamber; and an exhaust chamber is connected to the first mixing chamber. The ejector where the fluid under pressure penetrates into the first expansion chamber along a plurality of directions extends in a plane that is substantially orthogonal to the central axis. A vacuum generator includes such an ejector.

  • Publication number: 20220339799
    Abstract: The invention relates to a fluid flow device comprising a plurality of fluid flow functional modules each fastened on a respective individual base comprising: two parallel lateral faces via which the bases are adapted to be placed against one another in such a manner that when the bases are placed against one another, two of the bases each have one lateral face that is free; a primary fluid transport channel passing through the base to open out in its two lateral faces in identical positions; and a front face along which the module extends so as to couple an inlet channel of said module with a secondary channel extending in the base from the front face and opening out in the primary channel. According to the invention, the device includes fastener means for fastening the bases to one another and leaktight coupling means for coupling the end of the primary channel opening out in one of the lateral faces to a source of fluid under pressure for feeding the modules.

  • Patent number: 7938466
    Abstract: A suction gripper device comprising a pipe for connecting a suction source to a suction gripper member, the pipe comprising a first channel formed by a downstream chamber (5) and by an upstream duct (7), a seat (9) being provided between the chamber (5) and the duct (7), a valve member (6) being mounted to move with clearance inside the chamber (5) between a bottom abutment (2a, 22) and the seat (9), and a second channel (10) forming a calibrated bypass in parallel with the first channel and bypassing the seat (9), being of section that is smaller than the section (S) of the clearance that exists in the chamber (5) between its inside surface and the outside surface of the valve member (6) that can move therein, wherein the second channel (10) is formed through the center of the valve member (6).
