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.
Claims20
An air conditioning apparatus comprising:
- a case;
- a rotatable member rotatably supported through the case such that a surface of the rotatable member is opposed to a surface of the case, and a closed space is provided between the opposed surfaces of the case and the rotatable member;
- and
- a viscous fluid having a predetermined coefficient of viscosity, wherein the closed space is filled with the viscous fluid.

A passage control device comprising:
- a case defining a passage through which a gas flows, the case having a case engagement portion;
- a rotatable member configured to be rotatable with respect to the case to control the passage, the rotatable member having a rotational engagement portion that is rotatably engaged with the case engagement portion and a closed space is provided between the rotational engagement portion and the case engagement portion;
- and
- a viscous fluid having a predetermined coefficient of viscosity, wherein
- the closed space is filled with the viscous fluid so that a predetermined resistance to rotate the rotatable member is generated.
