Title:
【発明の名称】振動挙動を改良したポンプまたはコンプレッサ等のマルチピストンエンジン
Document Type and Number:
Japanese Patent JP2003517534
Kind Code:
A
Abstract:
The invention relates to a piston engine which is essentially comprised of an engine shaft and a set of modules, each of which comprises a cylinder and a piston powered by the engine shaft in the cylinder, each module resulting in vibratory excitation of the engine at a determined fundamental frequency. Rather than introducing phase differences between the various vibratory excitations, as is the case in prior art, the invention introduces a frequency offset between the fundamental frequencies thereof in order to avoid a high-amplitude vibration at a common excitation frequency, arising from the spectral spread thus obtained.
