Based on more than 30 years of research and practical experience, this book is the first to combine theory and design guidelines dedicated solely to positive displacement compressors. After introducing the sound- and vibration-producing mechanisms common to different types of compressors, the author discusses free and forced vibrations of compressor housing shells, mainly for hermetically sealed compressors. He then examines vibration in casings and other components, such as suction and discharge tubes, and surging in coil springs. Detailed chapters explore the design and vibrations of automatic plate or reed valves as well as the analysis and design of suction and discharge mufflers.
