Title:
雪フィルタ
Document Type and Number:
Japanese Patent JP2007500655
Kind Code:
A
Abstract:
A snow filter for an airplane cabin air supply system is provided with a coned inlet screen which allows some air to pass through and some snow to be retained. The coned configuration diverts much of the air and snow toward a downstream conical retaining and collecting screen positioned toward the outlet of the snow filter. Snow is retained and collected at this point while air is able to pass through the screen. Downstream of the coned inlet screen and upstream of the conical retaining and collecting screen is an open air flow mid-portion that enables tortuous flow of air as the snow is directed toward the conical retaining and collecting screen in an annular collection volume. The outlet of the snow filter is provided with a contact sleeve that allows the snow filter to be fittingly received by a surrounding corresponding air duct. Thus a snow filter is provided that effectively separates snow from a flow of air while maintaining a clog-free path.
