[0002]

2. Description of the Related Art In recent years, an air conditioner for a vehicle has been proposed, which is equipped with a four-way valve and air-conditions the interior of a vehicle by heat pump cooling and heating.

Conventionally, this type of heat pump has been used for cooling and heating.
As the method of supporting the one-way valve, for example, as in the method of supporting the four-way valve of a home air conditioner, a pipe connected to the four-way valve is used so that vibration from the compressor is not transmitted to the four-way valve. Was supported.

However, when the heat pump cooling and heating apparatus is mounted on a vehicle, the vibration of the road surface or the like is large, so that the above supporting method causes a large vibration to be transmitted to the four-way valve, which is disadvantageous in terms of durability of the four-way valve. Furthermore, since the pipe connected to the four-way valve has a bent structure, it is disadvantageous in terms of dimensions.
