Abstract: A flowpath structure includes: a supply channel in which a fluid to be supplied to an apparatus flows; a discharge channel in which the fluid discharged from the apparatus flows; and a pilot type opening-and-closing valve disposed in either one channel of the supply channel and the discharge channel. The opening-and-closing valve has a main valve arranged in the either one channel, a pilot channel connecting the supply channel and the discharge channel with each other, a back pressure chamber defined in the pilot channel, and a pilot valve that opens and closes a portion of the pilot channel closer to the discharge channel than the back pressure chamber. The main valve opens and closes the either one channel based on a change in an internal pressure of the back pressure chamber caused by an opening-and-closing operation of the pilot valve.

Abstract: A vehicular temperature regulation device includes a refrigeration cycle, a high-temperature cycle, and a low-temperature cycle. The refrigeration cycle includes a heating heat exchanger configured to heat the heat medium in the high-temperature cycle by exchanging heat between the refrigerant and the heat medium, and a cooling heat exchanger configured to cool the heat medium in the low-temperature cycle by exchanging heat between the refrigerant and the heat medium. The vehicular temperature regulation device includes a connection portion that connects the high-temperature cycle and the low-temperature cycle, a regulation portion configured to regulate a flow of the heat medium, and a controller. After the controller stops the compressor, or after the controller receives a stop command of stopping the compressor, the controller controls the regulation portion, a first pump, and a second pump to exchange the heat medium between the high-temperature cycle and the low-temperature cycle.
