Claims

[Scope of utility model registration request]

One or two chambers that communicate with the low temperature gas flow path and two or one chamber that communicate with the high temperature gas flow path, and two chambers that selectively communicate with either the low temperature gas flow path or the high temperature gas flow path. While the chambers are arranged alternately in a row with intervening chambers, a switching shaft passing through these chambers is provided so as to be movable in the axial direction, and valve holes that act in mutually opposite directions are formed in the partition wall of each chamber that the shaft passes through. At the same time, a valve is attached to the shaft, and the valve of the chamber communicating with the low temperature gas flow path is a movable valve that can be moved relative to the shaft within a certain range when the valve hole is closed, and the high temperature gas A four-way valve for switching a flow path between high-temperature gas and low-temperature gas, characterized in that a valve of a chamber communicating with the flow path is fixed to the shaft.
