Abstract

Système de nettoyage d’une surface optique La présente invention concerne un système de nettoyage (4) d’une surface optique (8) d’un capteur (2), comprenant un dispositif de soufflage (24) d’un flux d’air comprenant au moins une bouche de sortie (38) du flux d’air configurée pour projeter le flux d’air en direction de la surface optique (8) du capteur (2), et un dispositif de nettoyage par projection de liquide (26), comprenant au moins une buse de projection (62) de liquide, configurée pour projeter un jet de liquide sur la surface optique (8) du capteur (2), le dispositif de nettoyage par soufflage (24) étant configuré pour que le flux d’air en sortie de la bouche de sortie (38) forme une barrière protectrice du jet de liquide projeté par l’au moins une buse de projection du dispositif de nettoyage par projection de liquide (26). (figure 1)System for cleaning an optical surface The present invention relates to a system (4) for cleaning an optical surface (8) of a sensor (2), comprising a device (24) for blowing an air flow comprising at least one outlet mouth (38) for the air flow configured to project the air flow towards the optical surface (8) of the sensor (2), and a liquid projection cleaning device (26), comprising at least one liquid projection nozzle (62), configured to project a jet of liquid onto the optical surface (8) of the sensor (2), the blowing cleaning device (24) being configured so that the air flow at the outlet mouth (38) forms a protective barrier for the jet of liquid projected by the at least one projection nozzle of the liquid projection cleaning device (26). (figure 1)
