Abstract (en)
The invention relates to a device for lifting objects (15) by making use of a sub-atmospheric pressure, whereby the device is provided with a chamber (42) in which a sub-atmospheric pressure can be generated. A valve (45) located in said chamber has a valve stem (44) extending to a point beyond the chamber (42), through a passage (43) provided in the bottom wall (40) of the chamber. The lower end of the valve stem (44) is located near an opening (11) surrounded by resilient material (10), which is located at the bottom side of the device. The valve (45) and the valve stem (44) can be put from a first position, in which the passage (43) in the bottom wall (40) of the chamber (42) is closed by the valve, into a second position, in which the valve is located spaced from the bottom wall, and in which the chamber (42) is in open communication with the opening (11) surrounded by the resilient material (10). The valve (45) is secured to the lower end of a bellows-shaped means (46) disposed in the chamber (42), said bellows-shaped means being retained between the valve (45) and a fastening means (47, 48) located spaced from the bottom wall (40) of the chamber (42). The interior of the bellows-shaped means (46) is in open communication, via a passage (49) provided in the valve (45) and in the valve stem (44), with the opening (11) surrounded by the resilient material (10).
