Patent ID: 8292261

Claim:
A water and/or air dispenser for a snowmaking system in connection with water and/or air supplying ducts ( 6 , 7 ), comprising: at least one valve ( 9 ) associated with an electric actuator ( 10 ), said actuator ( 10 ) being connected to a electric power source ( 12 , 19 ) and associated with a management means ( 11 ) to ensure operation of said valve ( 9 ) between open and closed configurations thereof, said electric actuator ( 10 ) being connected to the electric power source ( 12 , 19 ) via a charger module ( 17 ), followed by a capacitor unit ( 16 ) and a voltage up-converter unit ( 18 ), said capacitor unit ( 16 ) configured to store, and then return, a quantity of energy necessary for complete actuation of said valve ( 9 ), said charger module, capacitor unit and voltage up-converter unit forming security means that is configured, upon an occurrence of a voltage cut-off at the power source ( 12 , 19 ), to return said quantity of energy from said capacitor unit and cause said valve to be positioned into a pre-determined security configuration.
