Motor vehicle headlamp lens washer - has fluid released through multiple nozzles from high pressure warmed supply container

摘要

The container is heated to a temp of over 50 deg. and has an overpressure of at least 5 atm. The reservoir is mutated in the flow circuit of the vehicle engine cooling fluid. Alternatively the reservoir can be heated by the vehicle exhaust gas. the overpressure is achieved by compressed air and the reservoir is thermally insulated. It is made from elastic, deformable material. The jets are operated by the driver by means of magnetically actuated valve, to spray directly onto lamp lenses.
