A windshield wiper blade cleaning system for a vehicle includes a plurality of wiper blades for movement across a windshield of a vehicle. The windshield wiper blade cleaning system includes a nozzle body adapted to be disposed in an air intake plenum of the vehicle and connected to a source of fluid. The nozzle body has a nozzle to extend above the wiper blades in response to fluid pressure from the source of fluid to spray the fluid through the nozzle and onto the wiper blades to clean the wiper blades.

Windshield wiper blade cleaning system

A windshield washer nozzle for an automotive vehicle, including a housing for retaining the nozzle, at least one fluid input port defined by the housing; and at least a first flow path and a second flow path defined by the housing in fluid communication with the fluid input port. Separate pressure flow control valves are retained in the first flow path and the second flow path, wherein fluid at a pressure below a pressure P can be directed through the input port and caused to flow through the first flow path, although flow is blocked through the second flow path. Alternatively, fluid in excess of a pressure P can be directed through the input port and caused to flow through the second flow path while flow is blocked through the first flow path.
