    Abstract: 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.

    Abstract translation: 在优选的形式中，本公开涉及一种用于清洁车辆车辆的后挡板窗的窗户清洁系统。 所述窗户清洁系统包括刮水器单元，所述刮水器单元具有由所述后挡板支撑的窗户刮水器，用于通过内侧和外侧行程跨过所述窗户的外表面进行振荡运动;以及驱动装置，用于通过其冲程移动所述刮水器。 驱动装置包括一个流体马达，用于当流体压力传递到其中时，通过其外侧冲程移动刮水器;以及弹簧装置，用于当流体压力未与流体马达相通时，通过其内侧冲程移动刮水器。 窗户清洁系统还包括垫圈单元，其具有用于将洗涤剂流体引导到窗户上的洗涤器喷嘴和用于将洗涤剂流体在压力下输送到洗涤器喷嘴的可手动致动的泵装置。 窗户清洁系统还包括协调器装置，其响应于由泵装置输送的加压流体，以使流体压力源与流体马达连通，由此泵装置的致动使刮水器通过其外侧 冲程和洗涤液喷射到窗户上。

    Abstract: In a preferred form, this disclosure relates to a combined manually actuatable washer pump and control means for controlling operation of a washer and wiper unit of a tailgate window cleaning system for a station wagon vehicle. The combined washer pump and control means comprises a depressible pumping element and a manually manipulatable actuating means including a pair of serially arranged plungers for controlling communication between a pressure source and a fluid motor of the wiper unit and for depressing the pump to initiate washer unit operation. The actuating means is constructed and arranged such that partial depression thereof will cause the plungers to move relative to each other to effect wiper unit operation alone and full depression thereof will cause conjoint energization of the wiper and washer units.

    Abstract translation: 在优选形式中，本公开涉及一种组合的可手动致动的清洗泵和用于控制用于车辆车辆的后门窗清洁系统的垫圈和刮水器单元的操作的控制装置。 组合的清洗泵和控制装置包括一个可按压的泵送元件和一个可手动操纵的致动装置，其包括一对串联布置的柱塞，用于控制刮水器单元的压力源和流体马达之间的连通，并且用于按压泵以启动洗涤器单元操作 。 致动装置被构造和布置成使得其部分按压将导致柱塞相对于彼此移动以实现单独的刮水器单元操作，并且其全压下将引起擦拭器和垫圈单元的联合通电。
