Abstract
An arrangement for washing lenses of headlights comprises a source of washing liquid, conveying conduit communicating with the source and arranged for flowing the washing liquid therethrough, a nozzle communicating with the conveying conduit and arranged for admitting the washing liquid from the latter and issuing the same toward the lens to be washed, and a rotary pump communicating with the conveying conduit and operative for inducing the washing liquid to flow from the source of the nozzle through the conveying conduit. The pump has a chamber into which a supply pipe of the conveying conduit is opened, and a rotor which has a projecting portion extending into the supply pipe. The rotor has a plurality of blades which are circumferentially spaced from one another so that a plurality of gaps are formed each between two adjacent blades, and a plurality of ribs which are arranged on the projecting portion of the rotor. Each of the ribs extends into a respective one of the gaps between two adjacent blades and is circumferentially spaced from the latter.
