である。DETAILED DESCRIPTION OF THE INVENTION The present invention is directed to a radiator which adjusts an excessive rise in the internal pressure of the radiator due to a rise in liquid temperature and air temperature, which occurs mainly during operation of an automobile engine or due to seasonal fluctuations, and brings the pressure in the radiator to the same level as atmospheric pressure. It relates to the structure of the cap, and the gist is that a plurality of grooves are provided in a spiral shape on the surface of the gasket that contacts the radiator body, with both ends being on the same surface and continuous on both the inner and outer peripheries, and in particular, the structure of the gasket. The purpose of this structure is to prevent the cross-sectional shape of the groove from being crushed due to strain on the seal when tightening the radiator cap to the radiator body, thereby preventing loss of its function. be.
以下、本発明を図示の実施例によって更に詳細に説明す
る。Hereinafter, the present invention will be explained in more detail with reference to illustrated embodiments.
第１図においてパツキン１０はおさえ１１と下ぶた１２
とにはさまってラジェターキャンプを構成しラジェタ一
本体にとりつけられる。In Figure 1, the packing 10 is the presser 11 and the lower lid 12.
A radiator camp is formed by sandwiching it between the radiator and the radiator, and it can be attached to the radiator itself.
パツキンに於けるラジェタ一本体と接する面に両端が同
面の内外両周縁に連続する数条の右方向スパイラル状溝
２１を放射配置に設けられている。Several rightward spiral grooves 21 are provided in a radial arrangement on the surface of the packing that comes into contact with the radiator body, both ends of which are continuous on both the inner and outer circumferential edges.
第３図は溝の断面形状を示すものであって、溝の深さは
０．５〜１．５ｍｍが、また溝の本数は４〜７本が望ま
しいがそれに限るものではなく、ラジェター内の圧力が
大気圧と同程度に保たれかつ液体が漏れないように溝の
深さ本数の関係で設計されればよい。Figure 3 shows the cross-sectional shape of the groove, and the depth of the groove is preferably 0.5 to 1.5 mm, and the number of grooves is preferably 4 to 7, but is not limited to this. The depth and number of grooves may be designed so that the pressure is maintained at the same level as atmospheric pressure and liquid does not leak.
尚、第４図は溝の断面形状を■字形としたものである。In addition, in FIG. 4, the cross-sectional shape of the groove is shaped like the letter ``■''.
本発明の作用、効果を表１に示す。Table 1 shows the functions and effects of the present invention.
これにラジェタ一本体にとりつけられているゴムホース

キャップとを比軟したものである。The rubber hose attached to the radiator body is sandwiched between two steel plates (thickness 3 mm x width 30 mm x length 10100 mm) before the engine starts and after 2 hours of continuous operation and compressed until the distance between the steel plates becomes a constant length. The pressure at that time was measured using a spring gauge, and the comparison was made between the conventional product and the radiator cap of the present invention.
ただし、ここで本発明ラジェターキャップ使用のゴムホ
ースの圧力が始動前より僅かにおちているのはエンジン
の稼動によりゴムホース温度があがり柔性がました結果
によるものである。However, the reason why the pressure in the rubber hose using the radiator cap of the present invention is slightly lower than before starting is because the temperature of the rubber hose increases due to engine operation and becomes flexible.

全性の確保に多大に貢献するものである。As described above, the present invention has a function to adjust the excessive rise in the internal pressure of the radiator due to the rise in liquid temperature and air temperature in the radiator, which occurs during the operation of the automobile engine or due to seasonal fluctuations, and to bring the pressure to the same level as the atmosphere. Needless to say, the main groove of the present invention is not linear but spiral, so there is no damage to the seal when tightening the radiator camp to the radiator body.
It is possible to avoid crushing the cross-sectional shape of the groove due to the strain caused by the strain, and the fear of loss of function due to the collapse greatly contributes to ensuring safety.
