A pneumatic mechanism designed to power the oscillatory movement of a vehicle’s window cleaning apparatus, employing compressed gas, typically air, as its energy source to drive the wiping blades across the windshield. This system was commonly found in older vehicles and industrial applications where readily available compressed air sources existed.
Such a device offers a method for windshield clearing that, historically, provided a simpler alternative to early electric motor systems. Its operation depended on the availability of a compressed air supply, making it suitable for vehicles equipped with onboard air compressors. The systems reliability, especially in environments where electrical components might be vulnerable, was also considered a benefit. However, factors like inconsistent wiping speed affected by air pressure fluctuations, and the potential for air leaks, led to its eventual replacement by more refined technologies.
