Selector valve and cooling system

摘要

A selector valve includes: a first valve element having a through-hole; a first housing having a radial hole through which fluid flowing though the through-hole passes, the first housing accommodating the first valve element; a second valve element having a through-hole; a second housing having radial holes through which fluid flowing through the through-hole passes, the second housing accommodating the second valve element; and a motor configured to integrally actuate the first valve element and the second valve element. A hollow space configured to suppress transfer of heat between the first valve element and the second valve element is formed between the first valve element and the second valve element. A hollow space configured to suppress transfer of heat between the first housing and the second housing is formed between the first housing and the second housing.

1. A cooling system comprising:
a compressor configured to circulate refrigerant; a first heat exchanger configured to perform heat exchange between the refrigerant and outside air; a decompressor configured to decompress the refrigerant; a second heat exchanger configured to perform heat exchange between the refrigerant and air-conditioning air; a first line and a second line connected in parallel with each other between the first heat exchanger and the decompressor, the first line and the second line being paths of the refrigerant; a cooling portion provided on the second line, the cooling portion being configured to use the refrigerant to cool a heat generating source; a third line through which the refrigerant flows between the compressor and the first heat exchanger; a communication line configured to provide fluid communication between the third line and a portion of the second line, the portion of the second line being closer to the decompressor than the cooling portion; and a selector valve connected to the first line, the second line and the communication line, the selector valve including:
a first valve element having a first through-hole,a first housing having a first flow passage through which fluid flowing through the first through-hole passes, the first housing accommodating the first valve element,a second valve element having a second through-hole,a second housing having a second flow passage through which fluid flowing through the second through-hole passes, the second housing accommodating the second valve element,a motor configured to integrally actuate the first valve element and the second valve element,a valve element heat insulating unit provided between the first valve element and the second valve element, the valve element heat insulating unit being configured to suppress transfer of heat between the first valve element and the second valve element, anda housing heat insulating unit provided between the first housing and the second housing, the housing heat insulating unit being configured to suppress transfer of heat between the first housing and the second housing.
