Abstract: A refrigeration cycle device includes a flow channel coupling member which constitutes at least one of a branching portion and a joining portion of a third refrigerant passage and a branching portion and a joining portion of a bypass passage. One of three refrigerant ports of the flow channel coupling member is directly connected to one of two refrigerant ports of a first switching device or a second switching device, and a sealing mechanism preventing a refrigerant leakage is provided in a connecting portion between the refrigerant port of the flow channel coupling member and the refrigerant port of the first switching device or the second switching device. The flow channel coupling member is fixed to one of the switching devices at a position different from a position of the sealing mechanism.

Abstract: An air conditioning apparatus has a case and a rotatable member that is rotatably supported by the case. The rotatable member and the case define a closed space between opposed surfaces thereof. The closed space is filled with a high-viscosity fluid having a predetermined coefficient of viscosity so as to generate a predetermined resistance to move of the rotatable member. The rotatable member is, for example, a door and a member of a link mechanism that operates the door, such as a lever plate, a link plate or the like.

Abstract: In a vehicle air conditioner, a defroster opening and a foot opening are provided at both right and left sides of a face opening. An outlet portion of a warm air passage has an enlarged portion offset to right and left side of the outlet portion of the cool air passage. During a bi-level mode, cool air from the cool air passage flows toward the face opening, and warm air from the warm air passage flows toward the foot opening, On the other hand, during a foot/defroster mode, cool air from the cool air passage and warm air from the warm air passage are mixed at an Inlet portion of the foot opening and the defroster opening and the mixed air is introduced into the foot opening and the defroster opening.
