US 2023/0407812 A1 · STIRLING ENGINE, AND METHOD FOR ADJUSTING SAME

Abstract

Provided is a Stirling engine whose characteristics can be easily adjusted. In a Stirling refrigerator as a Stirling engine including a piston as a reciprocating body that is configured to be able to reciprocate inside a cylinder having a central axis line X, and a mover of a linear motor and a connector as moving bodies that are coupled to and move together with this piston, since there is provided spacer(s) as an adjustment mechanism capable of adjusting the static position of a tip end of the piston inside the cylinder by adjusting the positional relation between the mover and the piston, the characteristics of the Stirling refrigerator can be easily adjusted.
