Title
(EN) SPRAY HEAD
(FR) TÊTE DE PULVÉRISATION
Abstract
(EN)
A spray head comprising: a spray plate including at least one aperture; and at least one restrictor in a substantially fixed spaced apart configuration with the spray plate; wherein a spacing between the spray plate and the at least one restrictor, in a vicinity of the at least one aperture, is configured such that, below a predetermined fluid pressure, a fluid is prevented from flowing through the spacing due to its surface tension, whilst above the predetermined fluid pressure the fluid is able to flow through the spacing and pass through the at least one aperture.
(FR)
Cette invention concerne une tête de pulvérisation, comprenant : une plaque de pulvérisation comprenant au moins une ouverture ; et au moins un limitateur dans une configuration espacée sensiblement fixe par rapport à la plaque de pulvérisation ; un espacement entre la plaque de pulvérisation et le(s) limitateur(s), à proximité de la/des ouverture(s), est configuré de telle sorte que, en-deçà d'une pression de fluide prédéfinie, un fluide est empêché de s'écouler à travers l'espacement en raison de sa tension de surface, tandis qu'au-delà de la pression de fluide prédéfinie, le fluide peut s'écouler à travers l'espacement et passer à travers la/les ouverture(s).
