This type of accumulator is usually called a hydraulic pneumatic accumulator.

従来の技術 前述の油圧空気式アキユムレータは、そのガス
口がどのようにしてシールされているかによつて
次の３種類に分類することができる。BACKGROUND ART The aforementioned hydraulic pneumatic accumulators can be classified into the following three types depending on how their gas ports are sealed.

１ 圧力ガスを封入するためにガス弁を使用する
もの。1 Those that use a gas valve to seal in pressurized gas.

２ 所定の圧力のガスを封入した後でガス弁を永

３ ガス弁を使用せず、ガスが自由に出入出来る
ようにしたもの。本考案はこの種のものとはあ
まり関係がない。3 A device that allows gas to freely flow in and out without using a gas valve. The present invention has little to do with this kind of thing.

なアキユムレータにとつては非常に大きな問題で
ある。 When a gas valve that can be opened to test gas pressure is used in an accumulator, a certain amount of gas in the fitting or meter is lost each time the gas pressure is tested. And this gas loss is a very big problem for small accumulators.

どうしてもガスが僅かに漏洩してしまう。そし
て、これは極めて普通にことである。又、アキユ
ムレータが機械的な振動の影響を受けるときにも
同様なことが発生する。 When using a gas valve in the form of a conventional check valve, small amounts of gas inevitably leak due to pressure fluctuations in the hydraulic circuit. And this is extremely common. A similar situation also occurs when the accumulator is affected by mechanical vibrations.

んでしまうことがある。 The gas charging valve is often fitted with a threaded cap to provide a more reliable seal; however, such caps are used at high pressures of several hundred bars and are subject to vibrations and fluctuating pressures. This cap itself may gradually become loose if it is affected.

る。Problems that the invention seeks to solve: Unlike ordinary containers such as bottles with removable stoppers, prior art accumulators that are subject to fluctuating pressures, shocks or vibrations effectively prevent gas leakage from the gas ports. I can't do that. and,
When a prior art accumulator seals its gas port, it is difficult to allow gas trapped in the sealing mechanism of the accumulator to escape.

ことができる。Means for Solving the Problem The gas port of the accumulator according to the present invention has a hole, a cup-shaped hollow sealing member provided in the hole, and a ball provided in the sealing member. However, the outer diameter of the seal member is approximately equal to the inner diameter of the gas port, and the diameter of the ball is larger than the inner diameter of the seal member. Therefore, when the ball is pressed into the sealing member, the outer surface of the sidewall of the sealing member is deformed outwardly to create a permanent leakage barrier between it and the wall of the gas port that can withstand vibrations as well as variable pressures. can form a seal. Then, a bypass passage is formed by forming a longitudinal groove inside the sealing member or a cross-shaped groove in the ball, and the air trapped between the ball and the sealing member is removed. It can be easily vented via a bypass passage.

われる。 When ball 55 is moved into seal member 42 as shown in FIGS. 2 and 3, if ball 55
5 and the floor 44, this gas would be compressed by the movement of the ball 55, and the ball 55 would not be able to fully enter the sealing member 42 due to the compressed gas. It will probably pop out. However, Figures 1 to 4
In the illustrated embodiment, gas evacuation is provided by a groove 56 in the seal member 42 that provides a bypass passage for passage of gas from one side of the ball to the other.
