<p>The present invention relates to a Stirling engine, and more particularly, to a Stirling engine that has a rotary displacer and a piston reciprocating a cooperation with a rotatable shaft of the displacer. The rotary type Stirling engine of the present invention comprises a hollow cylindrical housing that has a compressible working fluid hermetically contained therein and includes a hot heating portion for heating the working fluid and a cold cooling portion for cooling the working fluid in contact with the working fluid; a rotatable shaft rotatably supported by the housing while a portion thereof is accommodated within the housing; a displacer that has one end secured on the rotatable shaft and has an insulation surface placed in close proximity to the heating or cooling portion so as to block heat transfer from the heating portion to the working fluid or from the working fluid to the cooling portion upon rotation of the displacer; a volume-changing means communicating with the housing so that the working fluid flows therebetween, and having a volume varying in response to changes in the pressure of the working fluid; and a power-transmitting means for transmitting power, which is generated through repeated expansion and contraction of the volume-changing means in response to the changes in the pressure of the working fluid upon rotation of the displacer, to the rotatable shaft.</p> |
