摘要
In a preferred form, this disclosure relates to a window cleaning system for cleaning a tailgate window of a station wagon vehicle. The window cleaning system includes a wiper unit having a window wiper which is supported by the tailgate for oscillatory movement across the outer surface of the window through inboard and outboard strokes and a drive means for moving the wiper through its strokes. The drive means includes a fluid motor for moving the wiper through its outboard stroke when fluid pressure is communicated thereto and a spring means for moving the wiper through its inboard stroke when fluid pressure is not communicated to the fluid motor. The window cleaning system also includes a washer unit having a washer nozzle for directing the washer fluid against the window and a manually actuatable pump means for delivering washer fluid under pressure to the washer nozzle. The window cleaning system further includes a coordinator means which is responsive to pressurized fluid being delivered by the pump means to cause a source of fluid pressure to be communicated to the fluid motor whereby actuation of the pump means causes the wiper to be actuated through its outboard stroke and washer fluid to be squirted against the window.
