ABSTRACT:
A gravity actuated thermal motor which includes a rotor preferably in the form of a ring-shaped annulus which is filled with water. A plurality of collapsible bellows are connected to and extend inwardly from the outer peripheral wall of the annulus into the water-filled chamber. In communication with each of the bellows and extending outwardly from the outer peripheral wall of the annulus are a plurality of refrigerant-containing tanks, one tank being in communication with the interior portion of one bellows. A source of heat in the form of a hot water trough is positioned at the lower portion of the rotor so as to be intercepted by the refrigerant containers upon rotation of the annulus. The vapor produced by the volatile refrigerant expands the bellows and a locking device secures the bellows fully extended on the ascending side of the annulus. An automatic lock release is positioned near the top of the path of travel to release the bellows to enable same to contract during the time that the bellows at the bottom position is expanding. The constantly expanded bellows on the ascending side of the annulus ensures that the water within the annulus remains on the descending side to thereby impart rotary motion to the annulus which may be coupled out via a centrally positioned shaft.
