  • Stirling engine
    Patent number: 7257949
    Abstract: Through stroke control whereby the stroke of a piston is detected and controlled to be equal to a target stroke, the piston is prevented from colliding with a displacer, and the refrigerating performance of a Stirling refrigerator is enhanced. Different target strokes corresponding to different operation conditions of the Stirling refrigerator are stored in a storage portion in a control box, so that a linear motor can be driven with a target stroke that suits the current operation condition. Thus, the piston is prevented from colliding with a displacer, and the refrigerating performance of a Stirling refrigerator is further enhanced.

  • Stirling engine
    Publication number: 20050039454
    Abstract: Through stroke control whereby the stroke of a piston 1 is detected and controlled to be equal to a target stroke, the piston 1 is prevented from colliding with a displacer 2, and the refrigerating performance of a Stirling refrigerator 40 is enhanced. Different target strokes corresponding to different operation conditions of the Stirling refrigerator 40 are stored in a storage portion 111 in a control box 30, so that a linear motor 13 can be driven with a target stroke that suits the current operation condition. Thus, the piston 1 is prevented from colliding with a displacer 2, and the refrigerating performance of a Stirling refrigerator 40 is further enhanced.
