Oscillating washbox for cylinder head utilizing echelon formation nozzle alignment and an improved nozzle plate design

摘要

A bottom wall, a pitched top wall, and sidewalls cooperate to define a washbox for washing a part. The pitched top wall has an interior surface and an exterior surface. The exterior surface is pitched with a maximum distance from the bottom wall at a peak of the pitched top wall. The exterior surface is smooth and free from projections. The washbox further includes ports that extend through the sidewalls to provide fluid to the washbox. A plurality of bores extend through the pitched top wall and are arranged in a row echelon pattern for spraying the part.
