Description

駆動部３０は、複数の弁体部（７３）を少なくとも連動して駆動させる。複数の弁体部は、第２層側流路の内部に配置されており、第１層側流路と第２層側流路とを連通する連通路（７５ａ、７５ｂ）を通過する流体の流量を調整する。そして、流路切替装置は、第１層側流路形成部、第２層側流路形成部、及び駆動部がこの順番で積層配置されている。又、第１層側流路及び第２層側流路にて、互いに近接して配置される流路の間には、流路の間における熱伝達を減少させる断熱部（１３）が配置されている。 The drive unit 30 drives a plurality of valve body units (73) at least in conjunction with each other. The plurality of valve body portions are arranged inside the second layer side flow path, and the fluid passing through the communication passages (75a, 75b) communicating the first layer side flow path and the second layer side flow path. Adjust the flow rate. In the flow path switching device, the first layer side flow path forming portion, the second layer side flow path forming portion, and the driving portion are laminated and arranged in this order. Further, in the first layer side flow path and the second layer side flow path, a heat insulating portion (13) for reducing heat transfer between the flow paths is arranged between the flow paths arranged close to each other. to have.

又、第１層側流路形成部、第２層側流路形成部及び駆動部が積層配置されている為、複数の弁体部を相互に近接した位置に配置される。そして、駆動部は、複数の弁体部を少なくとも連動して駆動させる。この為、流路切替装置によれば、各弁体部に対してモータ等の駆動源を配置する場合に比べ、コンパクトで軽量な構成で、流体回路の流路構成の切替を実現することができる。そして、流路切替装置は、断熱部によって、近接して配置された流路の間における熱伝達の影響を抑えることができる。これにより、流路切替装置によれば、各流路を流れる流体の温度を適切に保つことができるので、流体回路における各構成機器を適切に利用することができる。 Further, since the first layer side flow path forming portion, the second layer side flow path forming portion, and the driving portion are arranged in a laminated manner, a plurality of valve body portions are arranged at positions close to each other. Then, the drive unit drives the plurality of valve body units at least in conjunction with each other. Therefore, according to the flow path switching device, it is possible to switch the flow path configuration of the fluid circuit with a compact and lightweight configuration as compared with the case where a drive source such as a motor is arranged for each valve body. it can. Then, the flow path switching device can suppress the influence of heat transfer between the flow paths arranged in close proximity to each other by the heat insulating portion. As a result, according to the flow path switching device, the temperature of the fluid flowing through each flow path can be appropriately maintained, so that each component device in the fluid circuit can be appropriately used.
