Abstract
An anti-siphon arrangement for a hydraulic system with a reservoir includes first and second flow paths providing hydraulic communication between the reservoir and a lower area. Each flow path includes an anti-siphon portion extending at least partly above a fluid level of the reservoir. First and second valves are configured, when configured in open states, to allow gas to flow from a gas source to the anti-siphon portions of the first and second flow paths, respectively.
