【発明の詳細な説明】 産業上の利用分野 この発明は、エネルギーの蓄積、衝撃ｖＩ衝。[Detailed description of the invention] Industrial applications This invention is based on energy storage and impact.
脈動吸収等に用いられる、液体封入ボール式アキュムレ
ータに関するものである。This invention relates to a liquid-filled ball type accumulator used for pulsation absorption, etc.
従来の技術
アキュムレータは、気体が作動液に比べて圧縮性が大き

のアキュムレータは１作動液出入口を備えた本体内を弾
性隔膜により液体室と気体室とに仕切られており５又、
その気体室にはガスが封入されている。Conventional accumulators utilize the fact that gas has greater compressibility than hydraulic fluid to buffer shocks, absorb pulsation, and the like. This accumulator has a main body with one working fluid inlet and outlet, and is partitioned into a liquid chamber and a gas chamber by an elastic diaphragm.
The gas chamber is filled with gas.
発明が解決しようとする課題
従来例のアキュムレータでは、気体室内のガスが圧縮さ
れると該気体室内の温度が上昇し、弾性隔膜（ブラダ）
が炭「ヒ破損してしまう。Problems to be Solved by the Invention In conventional accumulators, when the gas in the gas chamber is compressed, the temperature in the gas chamber increases and the elastic diaphragm (bladder)
However, the charcoal will be damaged.
又、ブラダが有効にしかも、長寿命で働く範囲は、おお
よそ体積変ｆヒ９／１０〜１／４であるが、ガスは液体
に比べ圧縮率が大きいので、少しの圧力変動幅でもすぐ
上記範囲を越えてしまう、そのため、使用圧力範囲は極
めて狭いものとなる。In addition, the range in which the bladder works effectively and has a long life is approximately 9/10 to 1/4 of the volume change f, but since gas has a higher compressibility than liquid, even a small pressure fluctuation range will quickly change the volume above the above range. Therefore, the operating pressure range becomes extremely narrow.
更に、ブラダが屈曲疲労などにより破損すると、アキュ
ムレータとしての機能を全く果たすことができなくなる
。Furthermore, if the bladder is damaged due to bending fatigue or the like, it will no longer be able to function as an accumulator.
この発明は、上記事情に鑑み、アキュムレータの使用圧
力範囲を無限大にするとともに、使用寿命を沖ばすこと
を目的とする。In view of the above circumstances, it is an object of the present invention to make the working pressure range of the accumulator infinite and to extend its useful life.

諭卜動液出入口から液圧回路内に排出される。When this accumulator is installed in the hydraulic pressure circuit for rY, when the hydraulic pressure in the circuit increases, the force flows into the pressure regulating chamber from the dynamic fluid inlet/outlet and presses the liquid-filled ball. Therefore,
The ball is compressed and becomes smaller, but since the compressibility of the liquid inside the ball is lower than that of gas, the amount of deformation of the ball is small.On the other hand, when the hydraulic pressure in the hydraulic circuit decreases, conversely to the above, As the ball expands, it is discharged into the hydraulic circuit from the rt=dynamic fluid inlet/outlet in the pressure regulating chamber.

通孔３ａｔ−備え、がっ、本体１の中央部に筒状に突設
され、その頂面は閉じられている。A pressure regulating chamber 2 of the main body 1 of the accumulator ACC communicates with a hydraulic fluid inlet/outlet 4 via a partition wall 3. The partition wall 3 is provided with a through hole 3at, which projects from the center of the main body 1 in a cylindrical shape, and its top surface is closed.
調圧室２内には、複数の液体封入ボール５が挿入されて

il: enters the pressure regulation chamber 2 from the source entrance/exit 4 and absorbs pulsation f
Yayoi, etc. will be held. The liquid 8 in the ball 5 has lower compressibility than gas, so the ball 5 can resist high compression fluctuations.
The amount of deformation of the liquid 8 is small, and the degree of rise in temperature of the liquid 8 is low.
従って、ボール５の炭化破損や屈曲疲労等による破損は
発生しない。Therefore, damage due to carbonization or bending fatigue of the ball 5 does not occur.

るおそれはない。Contrary to the above, when the hydraulic pressure in the hydraulic circuit 10 decreases, the ball 5 expands and discharges the fluid in the pressure regulating chamber 2 from the inlet/outlet 4 to the hydraulic port B10. At this time, the ball 5 descends while being guided by the partition wall 3 and returns to its original state.At this time, the ball 5 is sucked toward the entrance/exit slot 4, but the ball 5 The partition wall 3a prevents the ball from entering the inlet 4, so there is no risk of the ball being sucked into the two working fluid inlet/outlet ports 4 and being damaged.
