Multiple jet spray discharge head - has orifices of graduated dia. in rectangular arrays in sleeve

摘要

The multi-jet discharge nozzle is particularly for sanitary use, and rows of orifices of graded diameter are arranged adjacent to each other around the cylinder surface. They are grouped inside arcuate rectangles congruent and adjacent to each other. The orifice in the body supplying them is also congruent to these rectangles. The seal (38) between the body (31) and the cylindrical orifice sleeve (32) is in one piece, comprising two annular sections in planes at right angles to the axis of rotation of the orifice section, joined together by two bar portions parallel to this axis. These bars are spaced apart in the circumferential direction by a distance roughly equal to the length of the curved side of each rectangle enclosing a particular set of orifices.
