Abstract: An air conditioning diffuser is disclosed which includes two temperature sensitive elements. A first element detects room temperature and a second element ducting temperature. When room temperature increases during supply of cooled air, the first element moves a control unit upwards and this results in a first disc of the control unit moving away from a surface on a pivotally mounted link. The link pivots about its mounting so that a baffle hanger and a baffle move down allowing more cooled air to flow through the diffuser. When heated air is being supplied, the second element displaces the unit in the upward direction so that baffle control is transferred from the first disc and the first link surface to a second disc and a second link surface. The link surfaces lie one radially inwardly and one radially outwardly of the link mountings.
