Claim:
Device for cleaning vehicle surfaces such as headlamps, comprising: at least one nozzle carrier for mounting on a cleaning liquid supply tube, the nozzle carrier defining at least one cleaning liquid supply conduit for a pressurized cleaning fluid and being provided with at least one cleaning fluid distribution chamber, said chamber communicating with said cleaning liquid supply conduit and with at least one spray nozzle mounted on said nozzle carrier, wherein said distribution chamber is provided with at least one inlet port which in a non-pressurized state is closed by a fluid valve and wherein said fluid valve is designed as a springless valve, wherein said valve comprises a resilient diaphragm-type sealing member, wherein the sealing member comprises a cup-shaped diaphragm provided with a peripheral mounting flange, the diaphragm defining a substantially flat sealing surface yieldingly engaging the sealing seat and being displaceable relative to the mounting flange upon the action of the fluid pressure, wherein the sealing member forms the bottom of the cleaning liquid distribution chamber, and wherein the peripheral mounting flange is held in the valve housing by a cup-shaped cover, which is snap-fitted in a receiving opening of the nozzle carrier, the cover defining a compensation volume allowing displacement of the sealing member.
