摘要

The double acting stirling engine has two independent working gas zones, where the double acting piston-units are replaced by the double acting bellows systems. The double acting bellows system is comprised of a pair of bellows (1) for a piston side, and another pair of bellows (2) for another piston side. An actuator of the working gas zones hydraulically defines and is connected a piston rod (5). A filling body (4) is placed in the working gas zones to minimize a dead zone.
