ABSTRACT:
When an expansion mechanism (60) having an expansion chamber (62) is equipped with a backflow prevention mechanism (80) to suppress the outflow of fluid from the expansion chamber (62) to a communication path (72), it is possible to reduce dead volume in the expansion chamber (62) during operation with the circulation control mechanism (73,75,76) closed.
