Abstract
An adjustable device for exhaustion and/or supply of gases and gas supported particles, the device comprising at least one exhaustion and/or supply conduit which is pivotable in at least a vertical direction, whereby at least one force-producing balancing device is provided for balancing the exhaustion and/or supply conduit. In order to provide at such an adjustable device that the balancing device generates balancing forces which correspond with the correct balancing requirement, the force-producing balancing device cooperates with a compensating device which compensates for the differences between the balancing force that the force-producing balancing device exerts on the exhaustion and/or supply conduit and the force required for balancing the exhaustion and/or supply conduit in substantially all its positions.
