Abstract
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.
Claims16
A windshield wiper blade cleaning system for a vehicle comprising:
- a plurality of wiper blades for movement across a windshield of a vehicle;
- a nozzle body adapted to be disposed in an air intake plenum of the vehicle and connected to a source of fluid;
- and
- said nozzle body having a nozzle and an internal check valve operable to provide fluid communication from the source of fluid to said nozzle when the fluid pressure reaches a predetermined level, said nozzle having a stored position in said air intake plenum and an extended position above the air intake plenum and aimed downwardly and directly at said wiper blades, wherein said nozzle extends to the extended position in response to fluid pressure from said check valve to spray the fluid directly onto said wiper blades to clean said wiper blades while said wiper blades are in a parked, inactive position.
A windshield wiper blade cleaning system for a vehicle having a vehicle body with a window comprising:
- at least one wiper blade for connection to the vehicle body and for movement across the window;
- at least one nozzle body adapted to be disposed below an air intake panel and in an air intake plenum of the vehicle body and connected to the vehicle body and fluidly connected to a washer fluid reservoir containing washer fluid;
- and
- said at least one nozzle body having at least one nozzle and an internal check valve operable to provide fluid communication from the source of fluid to said at least one nozzle when the fluid pressure reaches a predetermined level, said at least one nozzle having a stored position in said air intake plenum and an extended position above the air intake plenum and aimed downwardly and directly at said wiper blades, wherein said at least one nozzle extends to the extended position in response to fluid pressure from said check valve to spray the fluid directly onto said at least one wiper blade to clean said at least one wiper blade while said wiper blade is in a parked, inactive position.
A windshield wiper blade cleaning system for a vehicle having a vehicle body with a window comprising:
- a plurality of wiper blades for connection to the vehicle body and for movement across the window;
- a plurality of nozzle bodies adapted to be disposed below an air intake panel and in an air intake plenum of the vehicle body and connected to the vehicle body and fluidly connected to a washer fluid reservoir containing washer fluid;
- and
- said nozzle bodies each having at least one nozzle and an internal check valve operable to provide fluid communication from the source of fluid to said at least one nozzle when the fluid pressure reaches a predetermined level, said at least one nozzle having a stored position in said air intake plenum and an extended position above the air intake plenum and aimed downwardly and directly at said wiper blades, wherein said nozzle extends to the extended position in response to fluid pressure from said check valve to spray the fluid directly onto said wiper blades to clean said wiper blades while said wiper blades are in a parked, inactive position.
