Abstract
A Stirling engine wherein a pressure variation is provided by a reciprocative movement of a displacer and is effected upon a power piston to obtain an output motive force. A first elastic film is provided at the displacer rod projecting into the crankcase so as to produce a first hermetically sealed space bounded by the expansion cylinder. A second elastic film is provided at the power piston rod so as to produce a second hermetically sealed space below the power piston. A pressure adjusting device equalizes the mean pressure of a reactive space, which includes the first and the second hermetically sealed spaces, and that of the crankcase.
