<p>A sealing element fora heat exchanger with thermal storage and transfer rotor, consist of a sealing plate with anti-friction layer and a chamber formed by a corrugated tube. The chamber communicates with the upper face of the anti-friction layer through a duct, which passes through the anti-friction layer in such a direction that as the mouth of the duct wears away and the layer becomes thinner, the mouth moves towards the zone of higher pressure. This movement leads to higher pressure inside the chamber, which compensates for the reduced elastic force exerted by the corrugated tube.</p> |
