Abstract
A sensor aperture cleaning system includes a fluid dispensing arm movable between a stowed position in which the fluid dispensing arm is outside a field of view of a sensor aperture and a cleaning position in which the fluid dispensing arm is disposed within the field of view of the sensor aperture. The system further comprises a piston mechanism, a housing sized to slidably receive the piston mechanism, and a biasing member disposed within the housing and configured to bias the piston mechanism. The piston mechanism is coupled to the fluid dispensing arm and is configured to move the fluid dispensing arm from the stowed position to the cleaning position in response to pressure on the piston mechanism from a pressurized fluid.
