  • Patent number: 6076872
    Abstract: The present invention relates to a vacuum manipulating device with a suction device, which can be connected via a lifting hose with a device generating a vacuum and which, for creating a suction on an object to be lifted or transported, can be placed on the latter. The suction device includes a control valve device with an opening which can be unblocked and blocked for controlling the vacuum prevailing in the interior of the suction device. The control valve device has a control element, which unblocks or blocks the opening and can be pivoted or rotated in the one or the other direction which, in the non-actuated state, takes up a settable neutral position with a degree of opening corresponding to the setting. In order to be able to set a defined poise, the device in accordance with the present invention is embodied such, that the control element is prestressed against a force-guided movable component in such a way that in the non-actuated state it rests against the latter with a detent area.
