This was the first link I looked at and what I saw is wrong. How disappointing.

Don't believe everything you see on the web. In my research I see lots of information that is pure garbage. Especially the academic stuff that ignores reality.

Anything positive to report Peter?

As I've been saying for 20+ years Fluid Power needs Trained/Dedicated persons so this type material is not contaminating all the correct information.

Oh well, someday maybe.

No. Rant follows.

George Keller published a book in 1968 called 'Hydraulic Systems Analysis'. I have provided links to it and it is available on the H&P book store. What about Jack Johnson? He as taught hydraulics for many years. I provided links to to his books a few days ago. The information is out there. One must be able and willing to understand them. THAT IS THE PROBLEM!!

Peter;

I thought I had George Kellers book but can't find it now. However I do have a large library as follows:

I have "Fluid Power Design Handbook," by Frank Yeaple, "Fluid Power Technology" by Don Norvelle, "Fluid Power Theory and Application" by James Sullivan, "Power Hydraulics" by Miachel J. Pinches & John G.Ashby, "Principles of Hydraulic System Design" by Peter J.Chapple, "Fluid Power Systems and Circuits" by Russ Henke, "Fluid Power Maintenance Basics and Trouble Shooting by Richard J. Mitchell and John J. Pippenger, "Basics for the Fluid Power Mechanic" by John J. Pippenger and Greg Godon, "Zero Downtime Pneumatics" by Dr. Z.J. Lansky P.E. and John J.Pippenger P.E., "Fluid Power the Hidden Giant by John J. Pippenger,P.E., "Fundamentals of Fluid Power" by William D. Wolansky,John Nagahosian & Russel W. Henke, "Basic Fluid Power" by Dudley A. Pease & John J' Pippenger, 'Designing Basic Pneumatic Control Circuits by Bruce McCord, "Hydraulics" by Deere & Company, "Trouble Shooting Hydraulic Circuits" by Rory McLaren, "Industrial Hydralic Contols" by Peter Rohner, "Industrial Fluid Power Vol's. 1,2 &3 by Womack Machine Supply Co., "Fluid Dynamics" by W.F. Hughes &J.A. Brighton, "YourGuide to the Electronic Control of Fluid Power by the National Fluid Power Association, all the company training books from Parker, Rexroth, Vickers Double A, one from Vickers from 1962 and I had an older one I can't find at present.

A 49 year collection of information and catalogs on Fluid Power that I have read at one time and a couple I have used for training classes many times.

Many times I have had to refer to the older catalogs I have also to figure out some problems on machines that were bulilt in the 40's.

I have no idea what my kids will do with them when I get to start Real Life.

Enough reminiscing but gives an idea of my background in Fluid Power.

And, What is the magical way to understand something that has no formal training and if it did no place to apply for work from anyone asking for trained persons??????????????????????????

Get enough people asking for Trained/Dedicated Fluid Power persons and the Colleges and Universities will provide them.

However the real problem is, most companies don't realize they have a need since they have Trained/Dedicated Electrical and Mechanical types that can work around the LEAKY, NOISY, TROUBLESOME, HOT RUNNING HYDRAULICS that cost so much to maintain since they don't have anyone who has knowledge in how it is supposed to operate.

Any discipline that depends on the Manufacturer, Distributor or their Salesman to implement, trouble shoot and maintain the equipment they produce or sell will stay in the Dark Ages until they change their ways or other equipment with Trained/Dedicated persons eliminates the need for that equipment.

My main hope is that I live long enough to see the day that Fluid Power is recognized, and not as John Pippenger put it in a book on Fluid Power, aptly called, "The Sleeping Giant."

It is more of a History of Fluid Power with a nostalgic look at the beginnings of the industry. What is so surprising is how much of the eqipment has anything but cosmetic changes when you see it applied today.

Also, except for what the Electrcal types have added, how little the applications have changed.

Fluid Power has been an interesting carreer to say the least and very rewarding to this country boy with two years of Tech School and a mechanical aptitude. A person that saw the life of a salesman as something to be desired and answered the first ad for such occupation which happily was from Miller Fluid Power. Who answered correctly when the interviewer put the Symbol for a 4-Way valve and got hired almost on the spot. That was in 1959 and as they say "The rest is history."

I still would like to see Fluid Power WAKE UP and become the force that is used correctly by Trained/Dedicated individuals and moves ahead like other disciplines that have Trained/Dedicated persons who apply and improve it.

Found another book shelf that had a few more Fluid Power offerings from different Autors.

"Pneumatics and Hydraulics by Henry L. Stewart, "Hydraulic Cartridge Valve Technology: by John J. Pippenger, "Electronically Controlled Proportional Valves" by Michael J.Tonyan, "Industrial Hydraulic Systems" by D.D. Banks & D.S. Banks, "Zero Downtime Hydraulics by John J. Pippenger and "Fundamentals of Hydraullic Engineering by Ned C. Whang and Carlos E. Hita, Actually this last book is on true HYDRAULICS, WATER systems. I did'nt know this when I bought it.

BTW, several of the books in my collection came from Friends and Students deceased Fathers Libraries. Also some came from EBay Autions.

I found a list of Electrical/Electronic training books below. Now, Compare the list of training material from a discipline that has TRAINED/DEDICATED persons applying it.

To a list of Fuid Power Training Books.

Plus the three I have proffered.
