Abstract
A spray head includes a sleeve provided with sprayers and divided into several chambers by a core element with several internal partitions. Each chamber is fed by passages and the main chamber is fed by a passage which passes through the cap, the cap including at least a spraying device in the form of a mini snow gun operating as nucleator.
Claims12
A snow-making spray head comprising:
- a tubular sleeve,
- a plurality of nozzles arranged radially on a periphery of said tubular sleeve,
- a core element disposed in said sleeve,
- said core element having radial partitions that divide the interior of said tubular sleeve in watertight fashion into a plurality of chambers,
- said nozzles communicating separately with said chambers,
- said core element having internal passages that feed water under pressure to said chambers,
- said chambers being supplied independently in relation to climatic conditions in order to increase quantities of snow produced.

A spray head, comprising:
- a tubular sleeve;
- a plurality of nozzles arranged radially on a periphery of said tubular sleeve;
- and
- a core element disposed in said sleeve, said core element having radial partitions that divide the interior of said tubular sleeve in watertight fashion into a plurality of chambers,
- said nozzles communicating separately with said chambers,
- said core element having internal passages that feed water under pressure to said chambers,
- said spray head adapted to occupy an upright position, said passages emerging into a lower portion of said chambers when said spray head is in said upright position, thus allowing total purge of the chambers once the supply of water to said chambers has stopped.
