The invention concerns a device consisting of at least a valve comprising a body ( 1 ) with a through channel ( 5 ), provided with several orifices and in particular orifices ( 4 ) serving both as intake and/or through passage, which orifices ( 4 ) are provided to enable, by means of accessory compo

The invention concerns a device consisting of at least a valve comprising a body ( 1 ) with a through channel ( 5 ), provided with several orifices and in particular orifices ( 4 ) serving both as intake and/or through passage, which orifices ( 4 ) are provided to enable, by means of accessory components, two bodies to be juxtaposed, and provide a common supply to several valves. The communication between the intake channel ( 5 ) and the outlet port ( 9 ) is provided by means of a cylindrical bore and a slide valve mobile in said bore. The outlet port ( 9 ) is located above the channel ( 5 ) and a bleed orifice ( 16 ) is located beneath said channel. Said bleed orifice ( 16 ) is in communication with the outlet port by means of the slide valve.

1. A supply device for a snow gun comprising at least one valve for circulating either pressurized water or pressurized air, which valve contains, in a single piece body:a through channel forming a fluid intake and also serving as a through passage for fluid;a fluid outlet port situated above the through channel;a bleed orifice located beneath the through channel;a cylindrical bore arranged according to an axis perpendicular to a longitudinal axis of the through channel and including a slide valve therein; said slide valve being mobile under the effect of a control member between a first position in which the through channel is placed in communication with the outlet port, and a second position in which the outlet port is placed in communication with the bleed orifice. 2. The supply device for a snow gun according to claim 1, wherein said body is arranged at the level of both ends of the through channel, in an identical fashion. 3. The supply device for a snow gun according to claim 1, wherein the slide valve comprises a bleed channel consisting of an axial bore located at its lower section, leading via a conduit into an outlet duct of the outlet port to perform the bleeding; said bleed channel adapted to be open or closed according to the position of the slide valve via a plug extending axially from a lower end of the body. 4. The supply device for a snow gun according to claim 3, wherein the slide valve is guided at its lower end into a jacket integral with the body; said jacket comprising a punched bottom for enabling fluid to flow during the bleeding; said bottom supporting the plug which closes the bleed channel when the slide valve is in said first position. 5. The supply device for a snow gun according to claim 3, wherein the cylindrical bore of the body between the through channel and the outlet duct of the outlet port comprises an intake zone shaped as a mixer enabling, in cooperation with a cylindrical section forming the plug of the slide valve, to vary the fluid flow rate as the slide valve moves between a completely open position and its closed position. 6. The supply device for a snow gun according to claim 3, wherein the control member comprises a reduction gear located in a cap that is attached to the top of the body in a tight fashion; said cap containing a mechanism plate on which are gathered in the form of an integrated circuit, various control systems of the reduction gear, circuits associated with limit switches triggered by a finger attached to an upper end of the slide valve, a control circuit of a resistor serving to reheat the body to prevent frost problems, and water pressure measuring circuits in the through channel and in the outlet duct, whereas the body is fitted with a connector or a tight grommet orifice. 7. The supply device for a snow gun according to claim 1, further comprising intake orifices of the through channel which comprise a double cylindrical bore, including an internal bore and an external bore, and fastening means for accessories associated with the body; said fastening means comprising keys in the form of needles adapted to be placed in diametrically opposite holes opening into the external bore and to cooperate with a groove provided on a corresponding cylindrical section of an accessory. 8. The supply device for a snow gun according to claim 7, wherein the keys are interconnected together, and form a U that can be secured to the body. 9. The supply device for a snow gun according to claim 7, wherein the accessory has the shape of a plug. 10. The supply device for a snow gun according to claim 7, wherein the accessory has the shape of a tubular socket which enables associating and juxtaposing two valve bodies.
