成を日差したものである。DETAILED DESCRIPTION OF THE INVENTION This 5L light resin 11.
This relates to a resin hose that can be curved into a circular shape with a diameter of 1.5 mm, and wrinkles occur at the curved part, especially for high-pressure fluids. The preferred configuration is shown in the sunlight.
従来、一般的に高圧樹脂ホースと言われる樹脂ホースは
、合成樹脂中空内層上に単岡または複数層の補強層を有

材あるいはゴム状弾性体を被覆して外被層を形成したも
のである。Conventionally, resin hoses, which are generally referred to as high-pressure resin hoses, have a single or multiple reinforcing layer on a hollow inner layer of synthetic resin, and are further coated with synthetic resin, thermoplastic polymer material, or rubber-like material on the outside. An outer covering layer is formed by covering an elastic body.
しかしながら、この従来の樹脂ホースでは、極めて重要

パクトに湾曲して使用することは不可能Ｃあった。However, this conventional resin hose still does not have sufficient functionality in terms of bending properties, which is one of the extremely important Bose properties. It was impossible to use it by bending it compactly because there were wrinkles and kinks in the parts that caused unstable conditions that were undesirable for use.

−背も必要どなるものであだ。In addition, as the hose is bent, the cross-sectional shape of the hollow section of the hose gradually changes from a circular shape to an elliptical shape, and as the hose bends, the resistance of the fluid flowing through the hollow section increases sharply. As the degree of curvature increases, it becomes necessary to pressurize each flow by an amount corresponding to the increase in flow velocity resistance.
-You need to be tall as well.
また、増大分の加圧によつＣ、ホースの耐久寿命も帖し
く短縮するものであった。Furthermore, due to the increased pressure, the durability life of the hose was also significantly shortened.
そこで、この樹脂ホースどして（よ、従来の樹脂ホース

であることが必要である。Therefore, compared to conventional resin hoses, this resin hose has a bending radius as small as possible and maintains a circular shape as much as possible, and even when curved, the hollow cross-sectional shape maintains a circular shape. It is necessary that abnormal conditions such as wrinkles and kinks do not easily occur on the inside.
また、ホースが使用される機器全体Ｉメコンパク１〜に

でさるようにすることが必要である。In addition, it is necessary to make the bending radius of the hose small so that it can be used in a state where the bending radius of the hose is small.

のである。Therefore, in order to eliminate the defects of conventional resin hoses, we investigated the operating state of the resin hose structure and found that there are two In the above cases), the condition between the reinforcing layer and the outer covering layer, the presence or absence of adhesion, and the operability of the bonded part - 1f, i', 'i 1',
The strength of 1 is the 0 radius of the resin hose, the occurrence of wrinkles and kinks, etc. 1y'+! We have now clarified that this has an influence on other physical properties of the material.

最大の効果をＩＲ来Ｊるもので゛ある。Zunawa also has strong adhesion between at least one component between the hollow inner layer and the reinforcing layer, between the reinforcing layers (for 2 or more plies), and between the reinforcing layer and the outer covering layer. By interposing the special contact layer (described later) Y1, the composite body consisting of each component can adjust the operation between the different 4F4 components as a buffer against bending by using a special adhesive layer. However, it should be constructed so that it exhibits a suitable integral, smooth, and curved behavior. In particular, when covering at least one component, it is best to interpose a special adhesive layer between the reinforcing layer and the outer covering layer, which have the greatest effect, to achieve the maximum effect with the minimum thickness. There is.

ことか可能となったものである。As a result of interposing a special adhesive layer between the components, uneven operation or friction does not occur between the hollow inner layer and the reinforcing layer, and between the reinforcing layer and the outer covering layer, and different operations between each component are prevented. When the Sung Dynasty was moved to the north, the curvature was formed, and wrinkles were formed against the curvature. Dynamic fatigue and frictional fatigue occur due to repetitive action, and as the product moves, it becomes possible to reduce the bending radius.

Jsu, the flexibility that is a characteristic of resin hoses can be easily twisted. On the other hand, if the material has a low melting point, it will increase the tendency for wrinkles to form.

得たものである。Furthermore, since the 14 components are integrated and exhibit a behavioral function with smooth bendability, friction occurs between each component, and the repeated action of pressurization and depressurization causes 'C' Also, the dynamic fatigue and frictional fatigue are in a state of 1-shibu "," and the breakage durability has been further improved. It is necessary to make the wall thicker, so it is possible to make the wall thickness as thin as possible, which contributes to weight reduction.In addition, by using a special adhesive initial layer, It was possible to form a resin hose having an even better buffering function (51).
