Operating device for a tube lifter, and tube lifter

An operating device for a tube lifter that comprises an end effector and a lifting tube having a tube interior, the lifting tube being able to be shortened by applying a vacuum to the tube interior and being able to be extended again by ventilating the tube interior, the operating device comprising:

• a lifting tube port for fluidic connection to the tube interior of the lifting tube;
• an end effector coupling for coupling the end effector to the operating device;
• a valve device for controlling fluidic connections;
• and
• an operating mechanism for actuating the valve device, wherein
• the valve device comprising a ventilation valve for ventilating the lifting tube port, and
• the ventilation valve has a valve flap, which is adjustable between an open position and a closed position, in the open position a flow path from the lifting tube port to the surroundings being released and in the closed position this flow path being closed, the operating mechanism comprising a first operating element and a second operating element, the first and the second operating element being mechanically coupled to the valve flap in such a way that by actuating the first and/or the second operating element an opening angle of the valve flap is adjustable.
