Abstract
A recycling secondary reservoir of a hydraulic system is charged with clean fluid from a primary hydraulic circuit. The secondary reservoir maintains clean fluid for use by a backup pump to cycle a hydraulic device. The secondary reservoir recaptures fluid used by the backup pump to maintain clean fluid that can be reused an indefinite number of times.
