本発明は配管の制振構造に係り、とくに空調機器用圧縮
機などに用いられる配管の制振要素に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a vibration damping structure for piping, and particularly to a vibration damping element for piping used in compressors for air conditioning equipment.

There is a method of stipulating the length of the piping as described in Japanese Patent Laid-Open No. 153974, or a method of shifting the natural frequency by attaching a weight to the piping as described in Japanese Patent Application Laid-Open No. 62-81792. There are also structures in which the piping is damped; for example, there is a method of covering the piping with a viscoelastic material, as disclosed in Japanese Patent Laid-Open No. 145262/1983. Also,
As disclosed in Japanese Patent Application Laid-Open No. 58-1.57842,
Another method is to attach a suction device made of a spring and mass to the piping to reduce vibration.

力に対しては粘性減衰の効果は小さい。Piping receives excitation force from a pressure generating source connected to it, such as a compressor, pump, or engine. The above-mentioned conventional techniques are less effective when the frequency of the excitation force changes. That is, it is difficult to avoid resonance for an excitation force whose frequency changes over a wide band, and the effect of viscous damping is small for an excitation force at a high frequency.

この母材を配管に係合する手段を設けたものである。In order to achieve the above object, the present invention includes at least one movable body inserted into the hollow part of a base material having a hollow inside,
Means for engaging this base material with the piping is provided.

で、周波数が変化する加振力に対して振動が小さい配管
を提供することができる。The operation of the present invention will be explained using FIG. 10. The base material 1 is attached to the pipe 5 by engagement means. The vibrations of the pipe 5 are transmitted to the base material 1 and further transmitted to the movable body within the cavity 2. At this time, the movable body 3 and the base material 1 move relatively differently, and friction and collision occur at the interface between the two. Vibration energy due to energy loss at this interface is consumed to reduce pipe vibration. Since the frictional force does not depend on the frequency characteristics of the applied force and acts in a wide range, it is possible to provide piping with small vibrations against the excitation force whose frequency changes.
また、可動体が複数個あるときは、可動体同志の衝突に
よるエネルギ損失がさらに振動低減の効果をもたらす。Furthermore, when there are a plurality of movable bodies, energy loss due to collision between the movable bodies further brings about the effect of reducing vibration.
