Shutter for closing opening in bulkhead of vehicle, has fixing units fixed to opening, shutter surface slid on fixing units, and moving unit moving surface of shutter toward opening with respect to rise temperature

摘要

The shutter (202) has a fixing unit i.e. hook (206), fixed to an opening, and a shutter surface (204) slid on the fixing unit. A moving unit moves the surface of the shutter toward the opening with respect to rise in temperature. The shutter surface is made of an expansible material. A body (208) is provided with a cavity (210) with the moving unit. A piston is mounted in the cavity, and the shutter surface is bound rigidly with the piston. The fixing units comprise legs (212) for guidance of the shutter surface, where the legs include bearing surfaces on a bulkhead.
