<p>The ejection duct consists of an insertion chute, opening into a refuse shaft, and having a fire-retardent door. The door is pivoted or displaceable in hinges or guides, in the lower region of the chute. It has an associated suspended flap, to close an opening into the duct. The flap is operated by elements, dependant upon movements of the insertion door. The flap is pivoted at the top, and opened by sacks. It is located opposite to, resp. on the same plane as the insertion door. When the door is closed, and a sack has passed, the elastic/flexible connection and locking elements lock the flap in position, thereby sealing the ejection duct relative to the refuse shaft.</p> |
