Abstract: A device (100) for producing artificial snow, provided with a body (101) including a pressurized water supply duct (10) and a pressurized air supply duct (20), at least one spray element (130) for spraying water or a mixture of air and water, at least one control valve (140) for adjusting the pressurized water and/or pressurized air supply of the spray element, and operating elements, in the form of at least one camshaft, for operating the control valve (140). The valve (140) is placed on the pressurized water and air supply ducts (10 and 20), and includes, on the periphery thereof, a water chamber (144) for the pressurized water supply thereof and an air chamber (145) for the pressurized air supply thereof. The valve (140) also includes a fixed body (141) in the general shape of a tube defining an inner receiving region (142) wherein a movable body (142) is housed, the body being translatably movable along a translation axis.

Abstract: Gas delivery valve, in particular of the demand-valve type, having a valve body (1) in which is made a main passage (11) for routing gas comprising a gas inlet orifice (12) and a gas outlet orifice (13), valve means (33) arranged on the internal passage (11) for routing gas, between the said gas inlet orifice (12) and outlet orifice (13), making it possible to control the flow of gas in the said main internal passage (11) for routing gas, a line (14) for detecting a pneumatic vacuum co-operating with the said valve means (33) in order to allow, at least temporarily, the flow of gas in the said main internal passage (11) for routing gas between the said inlet orifice (12) and outlet orifice (13). The valve further comprises a secondary passage (8) for routing gas which is fluidically connected to the main gas routing passage (11) upstream (11a) and downstream (11b) of the said valve means (33).
