【発明の詳細な説明】
（産業上の利用分野）
本発明は運動エネルギー（衝撃）を圧力に変換して吸収
する緩衝装置に使用される作動媒体に関する。DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a working medium used in a shock absorber that converts kinetic energy (impact) into pressure and absorbs it.

のである。この装置の概念図を第１図に示す。作動原理
は次に示す通りである。(Prior Art) A shock absorber converts a certain kinetic energy (impact) into pressure and absorbs it to smoothly stop an object. A conceptual diagram of this device is shown in FIG. The operating principle is as follows.
・ ある運動エネルギーを持った作動物体がピーはピス

され、作用物体をスムースに停止させるものでおる。な
お第１図における４は外側チューブを示す。- A working object with a certain kinetic energy acts on the oil 5 on the back of the piston, converting it into pressure. This pressure energy is dissipated into the atmosphere as thermal energy when the pressure oil is ejected from an orifice 4 provided in the inner tube 2. In this way, the kinetic energy of the working object is consumed until the piston moves to the end of its stroke, allowing the working object to stop smoothly. Note that 4 in FIG. 1 indicates an outer tube.
このような従来の緩衝装置は、衝撃時の圧力を吸収する
も、衝撃を吸収する作動媒体としての油は常時液体で存
在するため、装置すき間より流出し、量的に減少し、緩
衝装置としての効力が低下する欠点があった。Such conventional shock absorbers absorb the pressure at the time of impact, but since the oil as the working medium that absorbs the shock is always present in liquid form, it flows out from the gaps in the device and decreases in quantity, making it difficult to use as a shock absorber. The drawback was that the effectiveness of the method was reduced.

ある。(Problems to be Solved by the Invention) The present invention provides a shock absorbing device that does not have the above-mentioned drawbacks of the conventionally used shock absorbing working medium (oil) and that always exerts maximum shock absorbing power. It provides a working medium for
すなわち、本発明は、擬塑性で、かつチキソトロピック
性の石油系重質油よりなることを特徴とする緩衝装置用
作動媒体である。That is, the present invention is a working medium for a shock absorber characterized by being made of a pseudoplastic and thixotropic heavy petroleum oil.
ここで擬塑性でかつチキソトロピー性を有するというの
は、常時はゲル状態（又は固体状態）で存在するが、衝
撃が加わるとその粘度が低下し、液体（又はゾ／Ｉ／）
状態となし、圧力を吸収するが、衝撃吸収後は再度ゲル
状態（又は固体状態）にもどるという性質のことである
。Being pseudoplastic and having thixotropic properties means that it normally exists in a gel state (or solid state), but when an impact is applied, its viscosity decreases and it becomes liquid (or z/I/).
It has the property of absorbing pressure, but returning to a gel state (or solid state) after absorbing shock.
又、ここでいう石油系重質油とは、原油中の最も分子量
の大きな炭化水素及びその誘導体の混合物であ夛、その
組成はアスファルテン、レジン飽和分及び芳香族分よシ
成るもので、その代表的なものはアスファルトである。In addition, the petroleum heavy oil referred to here is a mixture of hydrocarbons with the largest molecular weight in crude oil and their derivatives, and its composition consists of asphaltene, resin saturation, and aromatic content. A typical example is asphalt.
アスファルトは常時（衝撃が加わっていない時）は１０
３〜１０’Ｐ （ポアズ）程度の従来用いられているダ
ンパー油よりも非常に高、い粘性を持つが、衝撃が加わ
ると急激に粘性が低下するという特性を持ち、ゾル状と
なる。Asphalt is always 10 (when no impact is applied)
It has a much higher viscosity than conventionally used damper oils of about 3 to 10'P (poise), but when an impact is applied, the viscosity decreases rapidly and it becomes sol-like.
しかし、衝撃が取シ除かれた後は時間の経過とともに回
復し、ｔヨぼもとの粘度にもどるというチキソトロピー
性を持っているものである。However, after the impact is removed, it recovers over time and returns to its original viscosity, which means it has thixotropic properties.
以下、具体例について本発明の効果について説明する。Hereinafter, the effects of the present invention will be explained using specific examples.

比較試験を行った。(Specific example) As examples of petroleum-based heavy oils that are pseudoplastic and thixotropic, vacuum residual oil (asphalt) and oil conventionally used as damper fluid in shock absorbers are used as examples).
A comparative test was conducted.

荷の位置にもどし、放置した。A model of the cylinder-type shock absorber shown in FIG.
A load (impact) was applied at a constant speed every unit time (100 hours), and the load required to compress the cylinder to its maximum stroke was compared. After applying the same load, the cylinder was returned to the no-load position and left alone.
試験開始直後と、試験５００時間経過後の結果を次表に
示す。The results immediately after the start of the test and after 500 hours of testing are shown in the following table.
