摘要： A tube connecting structure is formed with first and second cylindrical sections. The first cylindrical section includes: a joining cylinder with engagement holes disposed at a first end; a ring-shaped flange projecting radially inward from a second end; an inner cylinder extending co-axially toward the first end; and an inner cylindrical member separated axially from the inner cylinder. An O-ring is disposed co-axially between the inner cylinder and inner cylindrical member. Large and small diameter sections of the joining member align with a large-diameter section and small-diameter cylindrical section of the first tube, respectively, and are fitted into the space between the joining cylinder and the inner cylinder and inner cylindrical member. A second tube supported within the second cylindrical section is prevented from slipping out. The O-ring provides a fluid-tight seal between the first and second tubes.

摘要： A straight opposing member insertion section located at the end of a hose tube and has a ring-shaped groove for inserting a sealing ring. The opposing member insertion section has a ring-shaped tongue piece and/or a ring-shaped ring supporting section. Tongue-piece has a sloped surface and an overhang positioned over the ring-shaped groove. Ring supporting section is an indentation on the ring-shaped groove that protrudes away from the end of the hose tube. A sealing ring is tightly inserted into the ring-shaped groove. A ring-shaped engagement projection on the end of the tube-shaped opposing member is pushed into the opposing member insertion section until the engagement projection abuts the sealing ring. Sealing ring and the section of the tube wall with the ring-shaped groove can be constructed to handle seal deterioration. The resulting fuel hose connection structure has superior fuel sealing properties, fuel impermeability and can be contructed simplely and inexpensively.

摘要： A connection member includes a nipple portion formed at one end and a first end face portion formed at an end part of the nipple portion. A valve cap includes a small-diameter portion; a large-diameter portion; a valve seat portion having a valve seal surface formed on an inner circumferential surface of the valve cap and located between the small-diameter portion and the large-diameter portion; and a fitting end portion fitted to the outer circumferential surface of the end part of the nipple portion. A valve body includes a bottom portion having an abutment part to abut the valve seal surface; a cylindrical open end portion extending from the bottom portion; a second end face portion formed at the open end portion in such a manner as to face the first end face portion; a first sliding portion provided on the open end portion; and a first flow path portion provided in the first sliding portion. The valve body is accommodated within the large-diameter portion in an axially slidable condition. A compression spring is disposed between the first end face portion and the second end face portion and adapted to bias the valve body toward the valve seat portion of the valve cap. One end portion of a flexible tube is fitted to the outer circumferential surface of the valve cap and the outer circumferential surface of the nipple portion.

摘要： A hose connecting structure includes a hose whose central and engaging portion having a thermal flexibility resin which is molded by a blow molding method and a mating member which is inserted into the edge opening of the hose. The hose connecting structure further includes a ring-shaped sealing material and a first engaging portion which is disposed in the axial direction by a predetermined distance to the sealing material at either the edge portion of the hose or the mating member and a second engaging portion which is directly or indirectly engaged with the first engaging portion at either the edge portion of the hose or the mating member. Since the central and the engaging portion of the hose connecting structure includes a thermal flexibility resin which is molded by a blow molding method, the most suitable soft and hard resin for the appropriate portion can be used. When the engaging portion with the mating member and the central portion are molded integrally, the working efficiency is improved. The sealing material such as an O-ring is used for the engaging surface. Therefore, soft resin is not used for the engaging surface, and a free selection of resin is achieved. Moreover, the polishing of the engaging surface is not required.
摘要翻译：软管连接结构包括软管，其中心和接合部分具有通过吹塑法成型的热柔性树脂和插入软管的边缘开口中的配合构件。软管连接结构还包括环形密封材料和第一接合部分，该第一接合部分在软管或配合部件的边缘部分沿着轴向方向设置在密封材料上预定的距离，第二接合部分在软管或配合构件的边缘部分处直接或间接地与第一接合部分接合。由于软管连接结构的中心和接合部分包括通过吹塑法成型的热柔性树脂，因此可以使用适合于适当部分的最适合的软和硬树脂。当与配合构件的接合部分和中心部分一体地模制时，提高了工作效率。密封材料如O形圈用于接合表面。因此，软质树脂不用于接合表面，并且可以实现树脂的自由选择。此外，不需要对接合表面进行抛光。
