DRIVE Russian patent published in 1994 - IPC

FIELD: mechanical engineering. SUBSTANCE: heating and cooling means are made in the form of two hollow guide bolts with oppositely positioned slots for feeding hot and cold heat-transfer agents. Heating element is located between these slots. Each band is perforated and unilateral cross recesses are made between perforations to ensure their interlacing with each other. In this design bolts serve simultaneously as fasteners of bands, means for feeding heat- transfer element and as guides for displacement of output link. To avoid barren expenditure of heat-transfer agent use is made of bellows, which exclude feed of heat-transfer agent beyond band zone. EFFECT: improved efficiency. 3 dwg
