Output control apparatus for Stirling engines

摘要

A Stirling engine control apparatus includes a pressure reducing valve provided in a maximum cycle pressure line connecting a working space to a working gas compressor and a working gas tank via a first check valve, a pressure boost valve provided in a minimum cycle pressure line connecting the working space to the working gas storage tank via a second check valve, an operating lever pivotable about a movable fulcrum for controlling opening and closing of the pressure reducing valve and the pressure boost valve, a movable member on which the movable fulcrum of the operating lever is provided, and control means for positionally shifting the movable member upon comparing a target pressure corresponding to displacement of the operating lever and pressure within the minimum cycle pressure line.
