An eductor apparatus (1) having an air gap (2) and a venturi (3), a bypass channel (8) and a spray protection device (10) in the form of a deformable porous body to prevent splash back produced at the inlet to the venturi from escaping through the air gap (2). The spray protection device (10) may also function to absorb the energy of a misaligned water jet and provide an emergency flow path.
L'invention concerne un appareil mélangeur-éjecteur (1) comprenant un espace d'air (2) et un venturi (3), un canal de dérivation (8) et un dispositif de protection de pulvérisation (10) sous la forme d'un corps poreux déformable destiné à empêcher un retour d'éclaboussure, qui se produit à l'entrée du venturi, vers l'espace d'air (2). Le dispositif de protection de pulvérisation (10) peut aussi fonctionner afin d'absorber l'énergie d'un jet d'eau mal aligné et constituer un trajet d'écoulement d'urgence.
