Abstract:
A diffuser for controlling flow of air in an air conditioning system, the diffuser including an air flow control baffle, a first temperature sensitive element for sensing room temperature and having a first part which moves in response to changes in room temperature, first and second operating members connected to said first part for movement therewith in response to changes in room temperature, said members serving to move said baffle in opening and closing movements when they are themselves displaced by said first part of said first element, and a second temperature sensitive element for sensing the temperature in ducting through which heated and cooled air flows and having a second part which moves in response to ducting temperature variations, movements of said second part displacing said members between a first position in which one of them is effective to move the baffle in said opening and closing movements when cooled air is supplied to the ducting and a second position in which the other of said members is effective to move said baffle in said opening and closing movements when heated air is supplied to the ducting, there being means for adjusting the positions of said members with respect to said parts of said temperature sensitive elements.
