Abstract:
A hydraulic cylinder contamination prevention system for preventing large and small contaminants from entering into a hydraulic cylinder, including a hydraulic cylinder rod cover for underwater use with at least one automatic valve for preventing water circulation between the outside environment and the enclosed environment of the cylinder rod cover when the cylinder is stationary, egress of water from the cylinder rod cover when the cylinder is retracted, and ingress of water into the cylinder rod cover when cylinder is extended, and an external and abrasive cylinder rod scrubber.
