Abstract
A pneumatic windshield wiper includes a compressed air motor provided with a piston which mounts a pair of actuator vanes one of which functions with a fixed electric sensor on the motor housing to establish the 'park' position of the wiper blade. The other sensor actuator vane is adjustable along the length of the piston rod and functions with the sensor to establish the extended, adjustable position of the wiper blade. The sensor is included in an electronic circuit which controls operation of an electric solenoid valve and hence delivery of compressed air to the wiper motor.
