Quite a few years ago I had a limited experience of maintening pheumatic filling machines ect. I now find myself in a new job which requires a reasonable understanding of both pheumatics and hydraulics. Wishing to brush up on the little knowledge I obtained then I found this book to be an excellent read. It is both practical and also explains the theory of fluid power systems extremely well. I particulary found the circuit diagrams, symbols and explanation of how various components operate very useful. I would reccommend this book for anyone (student or otherwise) who is wishing to gain a good sound understanding in this field of fluid engineering.
