Automatic air inlet damper

摘要

An improved automatic inlet damper is disclosed which is particularly suited for use in oil burners. A flexible coupling (16-44) is connected between rotating shafts (10, 12) and supports an automatically actuated closure (64) which is moved into and out of engagement with an aperture (14) by a centrifugally actuated linkage (46-62, 78-110). See FIG. 1.
