Push button for a pressurised liquid distribution system

摘要

The push-button has a distribution chamber communicated with a supply conduit (10) and connected to upstream channels (11), downstream channels (12) and distribution channels (13). Each distribution channel converges towards an outlet opening (14) while enabling impaction of the liquid jets dispensed by the openings. The upstream and downstream channels extend longitudinally while forming upstream and downstream fluid flow sections in the chamber. An average transverse surface of the downstream fluid flow section is less than the average transverse surface of the upstream fluid flow section.
