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.

Push-button for a pressurized liquid distribution system

A spray nozzle designed to be mounted in a push button of a liquid distribution system, including a body equipped with an assembly tube that is defined by a front wall in which a distribution orifice is formed, wherein the inside face of the front wall is equipped with a vortex chamber that communicates with the distribution orifice, at least two radial tubes to supply liquid to the vortex chamber, and an annular duct to supply liquid to the upstream end of the tubes, in which the lateral inside wall of the tube is equipped with at least two axial grooves which respectively extend between an upstream end opening onto the rear edge of the tube and a downstream end opening onto the annular duct, wherein the grooves are positioned angularly so that each downstream end of a groove is equidistant from the two upstream ends of the tube adjacent to it on either side along the length of the annular duct.

Spray nozzle comprising axial grooves to provide a balance supply to the vortex chamber

The push-button is made up of two parts which fit into each other and define between them a whirl chamber, a part of which is formed by a cavity (38) defined inside the outer part on a face of the latter that is tilted in a direction and at a sufficient angle (&#x221d;), suitable for making it possible to remove the outer part from the mould 'along the axis' without damaging the cavity.
