Abstract: A limiter device is provided in a variable displacement compressor capable of varying a discharge displacement per revolution and compressing a fluid in a cycle. The limiter device includes an operating characteristic acquiring means for acquiring a predetermined characteristic during a compression operation of the compressor, and a varying means for varying the discharge displacement of the compressor to a minimum side when the predetermined characteristic obtained by the operating characteristic acquiring means exceeds a predetermined value. Thus, the limiter device can prevent the compressor from being brought into trouble such as locking and can protect a driving belt and other auxiliary equipment on a side of an engine, while it is unnecessary to provide a pulley with a limiter function.
