HARSH ENVIRONMENT SENSOR ENCLOSURE AND CLEANING SYSTEM

A harsh environment sensor housing and cleaning system includes sensor enclosures with a rotationally symmetrical lens that can be cleaned in a lens washing space defined by the sensor enclosure. Each sensor enclosure includes a motor coupled to the lens to rotate the lens within the sensor enclosure, allowing a dirty portion of the lens move through the lens washing space for cleaning, and a clean portion of the lens to be placed in front of a sensor or camera within the sensor enclosure. A sensor enclosure and cleaning system incorporates a control unit, fluid control valves, a manifold, and fluid conduits to deliver wash fluid to each sensor housing. The fluid control valves have a reduced part count and can be used to control flow of liquids or gasses such as air.
