Valves & Valve Gears for Steam Locomotives · 1940 ·

Now that Yodder &?Wharren’s Locomotive Valves &?Valve Gears has gone, this slightly later British  book is about as good as you will easily find on the subject. There may not be so much in the way of formulae and highly technical information, but this book is very accessible, and also has chapters on Poppet and Rotary Cam valve gears. 142 pages. 128 drawings/diagrams. Some B&W?photos. Paperback.
