Abstract
A high velocity, multiple-jet spray nozzle for use in carwash systems. Each nozzle comprises the axial unitary combination of a base, a nozzle carrier and a face plate. An inlet and a chamber are formed in the body and axially aligned flow passages are formed in the nozzle carrier and face plate so that when the components are assembled, five parallel jets arranged in a circular pattern are defined between the chamber and the outer surface of the face plate. Stainless steel nozzle inserts are press fit into the flow passages of the nozzle carrier and are held in place by the face plate. Screws hold the assembly together. The nozzles are preferably used in multiples to define a wide stream of washing fluid which can be used to attach mud, ice and other debris on the surfaces of a vehicle as well as on wheels and undercarriage. Each nozzle has an alignment axis marked on the face plate along which the spacing between adjacent nozzle outlets is uniform.
