  • Patent number: 4815302
    Abstract: The refrigerated or heated air flow within the storage chamber of a vending machine is varied by an air flow control device. A baffle plate or cover plate, or combination thereof, is used to control the direction of air flow. The position of these plates in turn is controlled by spring elements. One of the spring elements is formed of shaped memory alloy so that its recoil strength changes in accordance with its surrounding temperature. Thus, the difference in recoil strength between these spring elements changes with temperature. That difference is used to position the baffle and/or cover plates to control air circulation.
