  • 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: 20210323175
    Abstract: This two-stage ejector comprises a body (16) including: a compressed air intake (E); a compressed air injection nozzle (17) placed downstream of the air intake; a central duct (18); and an outlet mixer (19). The injection nozzle (17), the central duct (18) and the outlet mixer (19) are disposed along an axis (X-X?) of the ejector so that the ends of the axial duct are respectively spaced apart from the nozzle and from the mixer so as to form a first and a second suction zone (23, 25) that communicates with a single common air suction chamber (21).

  • Publication number: 20100175764
    Abstract: The invention relates to a device for controlling the opening and closing of a compressed gas consuming circuit (U), the device comprising a normally-closed two-position cutoff valve (2), said cutoff valve (2) having a pilot chamber (2a) and a counter-pilot chamber (2b) permanently in communication with a source (P) of compressed gas, directly for the pilot chamber (2a) and via a constriction (6) for the counter-pilot chamber (2b), the counter-pilot chamber including a purge branch connection (8) that is opened or closed by a two-position, two-port valve (9).
