Abstract
An attachment structure includes expansion valves used in a vehicle, and a housing to which the expansion valves are attached. The housing includes a flow path through which heat medium circulating in a heat pump cycle of an air conditioner of the vehicle flows, and the flow path is opened and closed by the expansion valves.
Claims12
An attachment structure for expansion valves, comprising:
- the expansion valves used in a vehicle;
- and
- a single housing to which the expansion valves are attached, wherein
- the single housing includes a flow path through which heat medium circulating in a heat pump cycle of an air conditioner of the vehicle flows,
- the flow path is opened and closed by the expansion valves,
- the expansion valves are aligned,
- the flow path includes an internal flow path through which two of the expansion valves communicate with each other, and a branch flow path through which the heat medium flows into the internal flow path from an outside of the single housing, and
- the expansion valves include a first expansion valve configured to open and close one end of the internal flow path, and a second expansion valve configured to open and close another end of the internal flow path.
