Abstract
The present invention is a thermally self-regulating nozzle for a snowmaking machine. The invention also relates to a system including the nozzle and method of snowmaking using the nozzle. The nozzle includes an outer housing made of a first material and a thermally separated inner housing, and a nozzle assembly attached to the outer housing by a member made of a second material having a thermal coefficient of expansion lower than the first material. The size of the nozzle outlet being dependent upon the expansion/contraction of the outer housing to accommodate more efficient snowmaking over a range of temperatures.
