sensor cleaning device

摘要

A sensor apparatus includes a cylindrical sensor window defining an axis and a tubular annular member fixed relative to the sensor window and substantially centered about the axis. The annular member includes a plurality of first nozzles and second nozzles disposed alternately around the annular member. The first nozzles each have a discharge direction in a radially inward and axial direction forming a first angle with the axis. The second nozzles each have a discharge direction in a radially inward and axial direction forming a second angle with the axis, the second angle being different from the first angle.
