Engine operated machine system

摘要

In an engine operated machine system including a hollow support rod connected at one end to an engine through a vibration insulator, an auxiliary weight is mounted at the other end of a crankshaft for generating a centrifugal force in the same direction as an inertia force of a piston, when the piston reaches top and bottom dead centers. Thus, it is possible to bring a center of gravity of the engine closer to the position of the vibration insulator, thereby suppressing the application of the vibration from the engine to the support rod to the utmost.
