A few rotary displacer Stirling engines whose displacers have one
gas pocket space at one side, and rotate in a main enclosed cylinder,
which is heated from one side and cooled from the opposite side without
any regenerator have been tried and studied for a considerable time by
the authors. They then tried to improve this engine by equipping them
with regenerators, because without regenerators, pressure oscillation
and efficiency are insufficient. Here, several types of regenerative
rotary displacer piston Stirling engines are proposed. One is the
contra-rotating tandem two disc-type displacer engine, using axial heat
conduction through side walls or by heat pipes and the other are single
disc-types with circulating fluid regenerators or heat pipes. A
contra-rotating type engine has been manufactured and experimented upon
in order to assess the effect of the regenerators. Here, experimental
results of an original rotary displacer Stirling engine without a
regenerator and a contra-rotating tandem displacer engine with a side
wall regenerator using axial heat conduction are reported, accompanied
by many discussions
