Oil Hydraulic Systems : Principles and Maintenance
"Bruce Burdette, Former Director of Maintenance Pan Am; Instructor Aviation High School for 10 years, "Explanation of contaminates in the system and resulting damage of hydraulic system components is presented in filters and filtration. The point of how a filtration engineer would design the location of an applicable filter or filters in a hydraulic system is well made. Hydraulic pumps were described in detail with good accompanying illustrations. Selection of pump types, by an engineer, based on efficiencies, flow rate and power, pressure, and displacement are well defined. The principle of flow control is well presented supported by mathematics and diagrams with a good description of check valves, pressure relief valves, and sequence valves.
