Abstract
A filtration device is disclosed. The device includes a filter inlet, a filter outlet, and a filter flow path from the filter inlet to the filter outlet. A filter in the filter flow path filters contaminants from lubricant flowing from a lubricant supply to a lubricant destination. A bypass flow path bypasses the filter in the event the filter becomes clogged. The bypass flow path has a bypass inlet in fluid communication with the filter flow path at a location upstream from the filter and a bypass outlet separate from the filter outlet and not in fluid communication with the filter outlet. The bypass outlet is normally closed to permit flow along the filter flow path and opens if the filter becomes clogged so that lubricant is directed along the bypass flow path and through the bypass outlet for disposal without going to the lubricant destination.
