【発明の詳細な説明】
湿式ライナ式シリンダの内燃機関においては、ライナと

グは老化によりシール性が低下するのである。DETAILED DESCRIPTION OF THE INVENTION In a wet liner type cylinder internal combustion engine, a rubber ring is attached to the fitting part of the liner and frame to seal the cooling water jacket. In marine engines, corrosion occurs in the gap in the fitting portion, which reduces the compression force of the rubber ring and reduces the sealing performance, and in general, the sealing performance of the rubber ring deteriorates as it ages.
これに対して従来は、ゴムリングを装着するとともに嵌
合部の間隙を充填剤で密封するようにしているが、上記
ライナとフレームの嵌合部のように、その周辺の形状等
により嵌合後に充填剤を注入して間隙を密封するのが困
難な場合が多いのである。Conventionally, a rubber ring is attached and the gap between the mating parts is sealed with a filler, but as in the case of the mating part between the liner and the frame mentioned above, the shape of the surrounding area makes the mating difficult. It is often difficult to later inject filler to seal the gap.
本発明はかかる実情に対処するものであり、ゴムリング

嵌合部においても核部の間隙を密封して水や油の漏出を
確実に防止し得るようにするものである。The present invention addresses this situation by making the cross section of the rubber ring into a shape with a void such as a square shape or a hollow shape, and by injecting a filler having the required properties into the void in advance. By keeping the ring in place, when the ring is crimped at the fitting part, the filler is pushed out from the cavity into the gap in the fitting part. This seals the gap and reliably prevents water and oil from leaking.
以下これを図に□示す実施例により詳説すると、第１図
において１は断面■状とされたゴムリングであり、その
Ｖ状をなす両辺１ａ、１ｂにはさまれた空所１ｃには適
宜材質を揮発性溶剤で溶解した充填剤２が注入せしめら
れている。This will be explained in detail below using an example shown in the figure. In Fig. 1, 1 is a rubber ring with a cross section of ■ shape, and the space 1c sandwiched between the V-shaped sides 1a and 1b is filled with appropriate space. A filler 2 made of a material dissolved in a volatile solvent is injected.
従って該リング１を第２図に示すように例えばライナ３

１ｂが圧着せしめられることによりその間の空所１ｃに
注入されていた充填剤２が該嵌合部５における間隙５ａ

部５の間隙５ａが完全に密封せしめられるのである。Therefore, as shown in FIG.
If it is attached to the fitting part 5 of the frame 4, both sides 1a +
1b is crimped, the filler 2 injected into the space 1c between them fills the gap 5a in the fitting part 5.
At the same time, the solvent evaporates in the gap 5a and solidifies, thereby completely sealing the gap 5a of the fitting portion 5.
又、第３図に示す実施例においては、ゴムリング１１は
断面が中空状とされ、その中空部１１ａに充填剤１２が

うということがないのである。Further, in the embodiment shown in FIG. 3, the rubber ring 11 has a hollow cross section, and a filler 12 is sealed in the hollow part 11a, and a cut groove 11b is formed on the outer periphery.
Therefore, when the ring 11 is crimped at the fitting part, it breaks from the cut groove 11b and the filler 11 in the hollow part 11a is pushed out into the gap of the fitting part. This seals the gap, and since the filler 12 is sealed in the ring 11, it will solidify if the filler is not injected immediately before mounting, as in the case of the ring 1 with the ■-shaped cross section. There is no need to put it away.

するのである。As described above, according to the present invention, the cross section of the rubber ring is shaped to have a cavity, and a filler having the desired properties is injected into the cavity in advance, so that
When the ring is attached to the fitting part and crimped, the filler is forced into the gap of the fitting part and completely seals the gap. It is now possible to easily and completely seal the gap at the fitting part, which was often difficult due to the shape of the engine. This has the effect of reliably preventing this.
