Logic element technology, which was originally given a euphoric reception as being the substitute for all conventional control units, has now established a firm niche for itself as an extension to spool valve technology. In many instances, it is an economic alternative to conventional circuitry. Particularly where the system must be made extremely compact, this technology shows considerable advantages.
In many cases, experiences gained with spool valves can be carried over directly into logic element technology without considering specific characteristics. However, in contrast to spool valve technology, logic element technology requires a certain amount of abstract thought. One must think in terms of pressure. In this respect, this book will certainly prove its worth.
The author clearly illustrates the points to be observed in planning, designing, and producing hydraulic systems when using logic elements. Diagrams and illustrations explain the multiplicity of functions which can be achieved with these valves, while lesser known, overly specialised models and variations have been deliberately excluded.
The design of a circuit using logic elements is given its own chapter, as are the examples of the practical examples controls already in use.
These two chapters are certainly not the only ones which will provide practical help to both users and those involved in both basic training and further education when moving into this area of technology.
Hydraulic control and drive technology encompasses an ever broadening area in career based education and training.
This book should provide the basis to provide those interested with up to date information on this
technology.
