20120025053 | SUCTION CUP HAVING REPLACEABLE SEALING SURFACES - A suction cup for a tool driven by vacuum is presented, the suction cup in a first or upper end arranged to be brought into fluid flow communication with a vacuum source and in its opposite end arranged to be brought tightly into contact with the surface of an object to be handled. The suction cup is in its lower end arranged to be coupled to a sealing ring having a sealing surface arranged between an outer periphery and a through-opening defined by an inner periphery, and the sealing ring in the region of its inner periphery having a lip arranged to engage with the suction cup, to which purpose the suction cup in its lower end has a circumferentially running groove) in which the peripheral region and the lip of the sealing ring is insertable under form fitting engagement and in a radially overlapping relation between the groove and the lip in the region (r) of engagement. | 02-02-2012 |
20100290925 | VACUUM GENERATOR, DRIVEN BY HIGH-PRESSURE AIR, AND HAVING MEANS ARRANGED THEREWITH FOR THE ACTIVE RELEASE OF AN OBJECT THAT IS GRIPPED IN A VACUUM-GRIPPER - A vacuum generator driven by compressed air and arranged to supply vacuum to a vacuum gripper element, wherein a chamber ( | 11-18-2010 |
20100045057 | EJECTOR DEVICE WITH VENTILATION ACTION - An ejector device adapted to generate a negative pressure with compressed air, which via a compressed-air duct is fed to an ejector, the device including a valve member arranged in the compressed-air duct and controllable in order to, in the open position, allow flow of compressed air to the ejector, an air suction duct arranged between the ejector and a gripping member driven by negative pressure, and a vent valve fluidly arranged with the air suction duct and that, in an open position, places the gripping member in communication with the atmosphere. The valve member embraces: a primary valve arranged in the direction of flow of compressed air; a secondary valve arranged downstream of the primary valve; a flow section of compressed-air duct between the primary and secondary valve, the vent valve communicating with the flow section so that, in the open position of the primary valve, is continuously being subjected to a closing air pressure, independently of the open or closed position of the secondary valve. | 02-25-2010 |
20090295170 | EJECTOR DEVICE - An ejector device effective to generate a negative pressure by element of compressed air fed to an ejector of the device via a compressed-air duct includes an air suction duct, a pressure sensor and an electrically activatable valve member arranged in the compressed-air duct for regulating the flow of compressed air to the ejector, as well as electrically supplied control electronics ( | 12-03-2009 |
