Abstract:
A windshield wiper protector mounted to a windshield wiper assembly to lift a wiper blade from a windshield, said protector, comprising a pressurized fluid container, a plunger installed in said pressurized fluid container, a solenoid operated device provided at one side of said plunger in said pressurized fluid container, a coil spring connected to said plunger at the same side of said solenoid operated device, while the other side of said plunger being adjacent to a pressurized fluid chamber, a push bar connected to said plunger at the opposite side of said pressurized fluid chamber, and an adjustable screw combined to an extended end of said push bar such that said adjustable screw being able to extend or retract, a fixing nut for screw combining said adjustable screw and said push bar,with such a structure, as said solenoid operated device is energized, a magnetic force is produced to attract said plunger with the result that the fluid pressure in the pressurized fluid chamber is lowered due to increase of volume, and said push bar retracts inwardly into said chamber, on the other hand, if said solenoid operated device is de-energized, the magnetic force produced therefrom disappears causing said coil spring to be released from a tensile force and stretched to reject said plunger outwardly, as a result, said push bar is forced to extend outwardly due to increase of fluid pressure caused by decreased volume of said pressurized fluid chamber.
