摘要：The invention relates to a device for protection of an optical sensor, comprising—at least one nozzle () for projection of air in front of the optical sensor (), the projectionnozzle being arranged on a side of the optical sensor and linked to an air discharge pump
() via a discharge conduit () such that the air projected by the air projection nozzle is flushwith the optical sensor,—and at least one suction conduit () arranged on the oppositeside of the optical sensor to the projection nozzle. The suction conduit is linked to thedischarge conduit of the pump, downstream of the pump, such that the suction in thesuction conduit is achieved by a Venturi effect.
