    Abstract: IN PREFERRED FORM, A COMPRESSOR HAVING AN OPEN ENDED HOUSING ADAPTED TO BE CONNECTED TO A CAM PORT ON AN ENGINE BLOCK. AN OPERATING ARM IS DRIVEN BY AN ENGINE CAM TO RECIPROCATE A PISTON WITHIN AN OIL FILLED CYLINDER WHICH INCLUDES AN INTAKE VALVE TO A SUMP IN THE HOUSING AND A RELIEF VALVE FOR FLOW OF EXCESSIVE OIL FROM THE CYLINDER BACK TO THE PUMP. A PUMP DIAPHRAGM IS OPERATED BY RECIPROCATION OF THE PISTON IN THE CYLINDER TO DRAW AIR INTO AND DISCHARGE AIR FROM AN AIR PUMPING CHAMBER WHICH INCLUDES A PLURALITY OF SHALLOW, NORROW RELIEF PASSAGEWAYS THEREIN TO REDUCE RE-EXPANSION OF COMPRESSED AIR IN THE CHAMBER. AN IMPROVED OIL BAFFLING ARRANGEMENT PREVENTS AERATION ON THE OIL SIDE OF THE DIAPHRAGM.

    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 preferred form, a fully automatic electrically operated leveling system for a vehicle having an undamped height sensing electric switch on one of a pair of air springs that operates to indicate vehicle height. An electric motor driven air compressor and electronic control circuit are mounted as a unit in a sealed storage tank along with a solenoid operated valve. The air compressor exhausts air from the springs into the tank to lower the vehicle chassis when it is unloaded. The solenoid operated valve directs air from the tank to the springs to raise the vehicle chassis when it is loaded. The electronic control circuit includes time delay means to prevent energization of the motor or solenoid in response to normal road movements of the vehicle.

    Abstract: In a preferred form, a valve assembly including an inlet and an outlet. The valve includes an oscillatable, damped shaft and a cam operator member coupled thereto by unidirectional clutch means that couple the sleeve and shaft for concurrent movement in a first direction and decouples the sleeve with respect to the shaft on movement of the sleeve in a second direction. In a first control position, the cam operator conditions a valving element to an open position so as to communicate the inlet and outlet. In a second control position, the cam operator is positioned to maintain the valve closed. Further, in the second position, the valve includes means responsive to a predetermined pressure at the inlet to open the valving element independently of the cam operator so as to relieve the pressure buildup by communicating the inlet with the exhaust.
