THIS paper outlines the advantages and disadvantages of present-day hydraulic systems.
Included in the discussion are: the blocked return line system for single-acting cylinders, the blocked pump inlet, and the basic open-center-valve system. More advanced designs mentioned are: open-center-valve systems with cylinders in series and with parallel cylinders, close-centered valve systems with pressure regulator, and the central hydraulic and accumulator systems.
The author points out that the advantages and disadvantages of each system depend to a great extent upon the design in which it is used.
