Dette er en oversættelse af den danske udgave, Hydraulik.

Hydraulics gives the reader a look into the world of hydraulics and the possibilities within.


The book begins by introducing principles of physics to provide a better understanding of relationships within elementary hydraulics.


The following sections offer extensive descriptions of the tasks and functions performed by individual hydraulic components — including pumps, motors, cylinders, pressure valves, directional valves, cartridge valves, flow valves, proportional valves, and accumulators. The book additionally discusses measurement technology and maintenance of hydraulic systems.


Hydraulics can be used as a reference for working engineers and service technicians, or as a textbook for those wishing to learn about or refresh their knowledge of hydraulic theory through independent study.


This book was written for use in a range of vocational secondary education programmes (Danish: erhvervsuddannelser), and can also be used by engineers, technicians, mechanics, engineer officers, etc.

This is an English translation of the Danish book Hydraulik (“Hydraulics”), 2nd edition, 2017 (product number: 81057-1).

The book additionally discusses measurement technology and maintenance of hydraulic systems.


To conclude, there is a large reference section containing a collection of formulas and tables.


The publisher believes that in its present form, this book will be of interest to a broad audience; for example, as a supplemental textbook for students, as a reference for working engineers and service technicians, or as a textbook for those wishing to learn about or refresh their knowledge of hydraulic theory through independent study.


This book is ideal for use in the following vocational secondary education programmes (Danish: erhvervsuddannelser) offered in Denmark: Automation engineer, Automation technician, Construction Plant Mechanic, Agricultural Machinery Mechanic and Maritime Service Engineer; as well as in continuing education courses in these fields.


The publisher wishes to thank all the companies that kindly provided materials for use in this edition.


The translation was produced by translation agency eTranslate ApS, with subject-specific terminology checked for quality by Svend Erik Thomsen at Danfoss A/S. Thanks a lot.
