Title (EN) VACUUM EJECTOR DEVICE
(FR) DISPOSITIF D'ÉJECTION DE VIDE
Abstract:
(EN) A vacuum ejector device (2) for generating at least partial vacuum to be supplied to a gripping member (4), comprising a device body (6) having an elongated shape along a longitudinal axis A. A movable sealing and venting element (24)is provided and is structured to selectively substantially close and seal,in a sealing position,a vacuum duct (16)when the air supply is activated, and to open or vent said vacuum duct to release or vent via a venting duct (26), in a venting position,the vacuum within the gripping member (4)when the vacuum source or air supply is deactivated. The sealing and venting element (24) is arranged essentially at the longitudinal axis A, and that the venting duct (26) is arranged and provides for fluid communication between the sealing and venting element (24) and a venting outlet port (28) provided at a long side of said elongated device body (6).
(FR) L'invention concerne un dispositif d'éjection de vide (2) pour générer un vide au moins partiel devant être appliqué à un élément de préhension (4), comprenant un corps de dispositif (6) ayant une forme allongée le long d'un axe longitudinal A. Un élément d'étanchéité et de ventilation mobile (24) est prévu et est structuré pour fermer et sceller de manière sélective et étanche, dans une position d'étanchéité, un conduit de vide (16) lorsque l'alimentation en air est activée, et pour ouvrir ou ventiler ledit conduit de vide pour libérer ou ventiler, par l'intermédiaire d'un conduit de ventilation (26), dans une position de ventilation, le vide à l'intérieur de l'élément de préhension (4) lorsque la source de vide ou l'alimentation en air est désactivée. L'élément d'étanchéité et de ventilation (24) est disposé sensiblement au niveau de l'axe longitudinal A, et le conduit de ventilation (26) est agencé et assure une communication fluidique entre l'élément d'étanchéité et de ventilation (24) et un orifice de sortie de ventilation (28) disposé sur un côté long dudit corps de dispositif allongé (6).
