Abstract
To provide a Stirling engine and a control unit for a Stirling engine capable of disposing a displacer unit and a power cylinder unit separately from each other, thereby increasing the degree of freedom of layout thereof. A displacer unit and a power cylinder unit of a Stirling engine E are disposed separately from each other. A compression chamber of the displacer unit is connected to an operation chamber of the power cylinder unit via a pressure conduit. A control actuator capable of arbitrarily controlling the displacer piston of the displacer unit is connected to the displacer piston.
Claims14
A Stirling engine including a displacer unit in which a displacer piston is slidably fitted in a displacer cylinder for partitioning an interior portion of said cylinder into an expansion chamber and a compression chamber, and a power cylinder unit having a power piston slidably fitted in a power cylinder for forming an operation chamber in communication with said compression chamber in said cylinder comprising:
- said displacer unit and said power cylinder unit are disposed separately from each other;
- said compression chamber is connected to said operation chamber via a pressure conduit;
- and
- a control actuator is operatively connected to said displacer piston for arbitrarily controlling the movement of said displacer piston.
