Title:
VIBRATION CONTROL DEVICE IN MODEL ENGINE
Document Type and Number:
Japanese Patent JP3923619
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To effectively absorb and relieve the vibration, by absorbing the vibration in a vertical direction and a rotating direction generated on an engine, by a vibration absorption elastic device, and absorbing and relieving the vibration in the rotating direction and the repulsion generated on an elastic body by a buffer means of a vibration absorption damping device.
SOLUTION: The vibration is generated on a single-cylinder engine at a low speed rotation such as the idling of the engine or the like, a high speed rotation, or the like. The vibration is absorbed by the elasticity of the circular rubbers 23, 27 of the vibration absorption elastic devices 20, 24 mounted on the supporting parts of both edges of an engine body 1. Further the vibration in a rotating direction, and the repulsion generated on the circular rubbers 23, 27 are acted on a vibration absorption damping device 28, and a piston 30 is advanced and retreated to a cylinder 32, so that the oil in an oil chamber 33 is moved left and right through an orifice 34 of the piston 30 to absorb the vibration by the oil, whereby the vibration of the engine is absorbed and relieved. Whereby the vibration can be prevented from transmitted to a machine body, the stable flight can be kept, and the generation of the failure and abnormality of various devices in an airplane can be prevented.
