A fluid flow device including a plurality of fluid flow functional modules each fastened on a respective individual base includes: two parallel lateral faces via which the bases are adapted to be placed against one another; a primary channel passing through the base to open out in its two lateral faces; 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; a check valve closing the secondary channel when the base is not provided with a module; and a top face in which there extends a tertiary channel opening out in the primary channel. The device further includes a fastener for fastening the bases to one another, leaktight couplers for coupling the primary channel and the tertiary channel to a source of fluid under pressure.

Fluid device for suction gripping

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.

Supersonic ejector with annular chamber

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 () and by an upstream duct (), a seat () being provided between the chamber () and the duct (), a valve member () being mounted to move with clearance inside the chamber () between a bottom abutment () and the seat (), and a second channel () forming a calibrated bypass in parallel with the first channel and bypassing the seat (), being of section that is smaller than the section (S) of the clearance that exists in the chamber () between its inside surface and the outside surface of the valve member () that can move therein, wherein the second channel () is formed through the center of the valve member ().
