Abstract:
1. A high-velocity, multiple jet spray nozzle for car wash applications comprising: a base having a fluid inlet in one side and a chamber opening to an opposite side and in fluid communication with the inlet; a nozzle carrier having a first side and a second side and a plurality of parallel straight sided fluid passages formed therein between the first and second sides, each of said fluid passages having an end portion of greater diameter than the rest of the passage so as to define an internal shoulder, the first side of the nozzle carrier being sealingly attached to the opposite side of the base around the open chamber such that the fluid passages are in fluid communication with the chamber; plurality of inelastic nozzle inserts disposed in the end portions of the nozzle carrier fluid passages adjacent the second side and abutting said shoulders and having straight sided passages formed internally therein of substantially smaller internal diameter than the internal diameters of the fluid passages in the nozzle carrier; said inserts having a length which is smaller as compared to the overall length of said passages; and a cover plate sealingly attached to the second side of the nozzle carrier and having a plurality of straight sided fluid passages formed therein in alignment with and in fluid communication with said nozzle inserts; the cover plate fluid passages having diameters which are substantially larger than the inside diameters of the insert fluid passages, but smaller than the outside diameter of the inserts thereby to trap the inserts between said cover plate and said shoulders.
