Abstract

L'invention concerne un système de nettoyage à haute pression (10) comprenant un appareil de nettoyage à haute pression (12), lequel possède une pompe (34) et un moteur (32) ainsi qu'une entrée de pompe (36) et une sortie de pompe (38) et un dispositif de commande (46), et comprenant au moins une unité d'éjection (16, 18, 20, 22, 24, 26) qui peut être amenée en liaison fluidique avec la sortie de pompe (38) pour l'éjection du liquide de nettoyage mis sous pression. Selon l'invention, en vue de perfectionner ce système de nettoyage à haute pression de manière à pouvoir obtenir le meilleur résultat de nettoyage possible de façon plus simple, ledit système de nettoyage à haute pression (10) possède une unité de détection (104) au moyen de laquelle peut être détecté le type de l'unité d'éjection (16, 18, 20, 22, 24, 26) qui se trouve actuellement en liaison fluidique avec la sortie de pompe (38) et qui est reliée en vue de la transmission de signaux au dispositif de commande (46). Au moins un paramètre de refoulement de l'appareil de nettoyage à haute pression (12) peut être adapté automatiquement par le dispositif de commande (46) en fonction du type détecté d'unité d'éjection (16, 18, 20, 22, 24, 26). L'invention concerne en outre une unité d'éjection pour un tel système de nettoyage à haute pression.
