Types of Stirling Engines
Stirling engines are classified to four types with viewpoint of working space. The alpha-type has two power pistons. The beta-type has a displacer and a power pisuton with the same cylinder. The gamma-type has a displacer and a power piston with indipendent cylinders. And the double-acting type has for power pistons and uses both the top and bottom sides of the pistons. Also the alpha-type is colled the two-piston type. The beta- and gamma-type are called the displacer type.
| Technical Terms | |
| Power Piston | This piston changes the volume between the working space and atmosphere. The engine works by this piston. |
| Displacer | The displacer moves the working gas from hot spaceto cold space, and does not change the volume in the engine. |
