A push-button for a pressurised liquid distribution system, the push-button including a body onto which an end piece is mounted around an insert so as to form a distribution chamber between said end piece and the insert, the distribution chamber being in communication with a supply channel intended
A push-button for a pressurised liquid distribution system, the push-button including a body onto which an end piece is mounted around an insert so as to form a distribution chamber between said end piece and the insert, the distribution chamber being in communication with a supply channel intended to be mounted on a feed tube for the pressurised liquid, the distribution chamber being successively connected to upstream channels, downstream channels and distribution channels, the distribution channels each converging towards an outlet opening while being designed to enable the impaction of the liquid jets dispensed by the openings, the upstream and downstream channels extending longitudinally while forming an upstream and downstream fluid flow section, respectively, in the distribution chamber, the downstream section having an average transverse surface which is less than the average transverse surface of the upstream section.

1. A push-button for a pressurised liquid distribution system, said push-button comprising a body onto which an end piece is mounted around an insert so as to form a distribution chamber between said end piece and said insert, said distribution chamber being in communication with a supply channel intended to be mounted on a feed tube for the pressurised liquid, said distribution chamber being successively connected to upstream channels, downstream channels and distribution channels, said distribution channels each converging towards one of a plurality of outlet openings while being designed to enable the impaction of the liquid jets dispensed by said outlet openings, the upstream and downstream channels extending longitudinally while forming an upstream and downstream fluid flow section, respectively, in the distribution chamber, said downstream section having an average cross-sectional area of which is less than the average cross-sectional area of the upstream section, characterized in that the upstream and downstream channels are formed at the interface between an interior wall of the end piece and an exterior wall of the insert, a concave impression is formed on at least one of said walls so as to be closed by the other wall while defining said channels, and each wall has at least one bearing surface between which the upstream and downstream channels are formed. 2. The push-button according to claim 1, characterised in that the distribution chamber further has an annular channel which is interposed between the supply channel and the upstream channels. 3. The push-button according to claim 1, characterised in that the number of downstream channels is equal to the number of upstream channels. 4. The push-button according to claim 3, characterised in that each downstream channel is in longitudinal alignment with an upstream channel. 5. The push-button according to claim 1, characterised in that each of the distribution channels have a cross-sectional area which decreases from upstream to down-stream. 6. The push-button according to claim 1, characterised in that the upstream and downstream channels are formed at the interface between an interior wall of the end piece and an exterior wall of the insert, a concave impression being formed on at least one of said walls so as to be closed by the other wall while defining said channels. 7. The push-button according to claim 1, characterised in that each wall has an upstream bearing surface between which the upstream channels are formed, and a downstream bearing surface between which the downstream channels are formed, the diameter of the upstream bearing surfaces being greater than the diameter of the downstream bearing surfaces. 8. The push-button according to claim 7, characterised in that the insert has a base over which a rod extends, the upstream channels being formed around the base and the downstream channels around the rod. 9. The push-button according to claim 1, characterised in that the downstream channels have a cross-sectional area which decreases from the cross-sectional area of the upstream channels to the cross-sectional area of the distribution channels. 10. The push-button according to claim 1, characterised in that the end piece has a seat in which the end of the insert is butt-mounted, said seat and said end each having a truncated cone-shaped geometry, said geometries being designed so as to form the distribution channels and the outlet openings therebetween. 11. The push-button according to claim 1, characterised in that the downstream end of each downstream channel has a truncated cone-shaped geometry designed to form a distribution channel. 12. The push-button according to claim 1, characterised in that the distribution chamber further has at least one intermediate channel, which is interposed between the upstream and downstream channels. 13. The push-button according to claim 12, characterised in that the intermediate channel is annular, the upstream and downstream channels terminating in said annular channel. 14. The push-button according to claim 13, characterised in that the distribution chamber has several intermediate channels connecting the upstream and downstream channels. 15. The push-button according to claim 1, characterised in that the body has a housing in which the insert is arranged, the end piece being connected inside said housing. 16. A pressurised liquid distribution system, comprising a pressurised device for withdrawing the liquid on which is mounted a push-button according to any claim 1, the distribution chamber being in communication with the feed tube for the pressurised liquid coming from said withdrawing device, so as to enable the liquid to be sprayed via impaction of the jets coming from the distribution channels.
