る。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a connector and a joint used for a high-pressure hose and the like, and particularly relates to a high-pressure hose and a pipe joint.
本発明が属する形式の管継手は、普通には、ホースの端
に圧着されるスリーブをもっており、ホースの端にはス
リーブの中に入るホース継手のひだ付肢をもっている。Pipe fittings of the type to which the present invention pertains typically have a sleeve that is crimped onto the end of a hose, and the hose end has a pleated leg of the hose fitting that extends into the sleeve.
普通には、流体が管継手を連通するとき、都合の悪いこ

体圧は、漏れ路を見出す努力をする。よくあるように、
流体がスリーブとホースの端の間に入シ込むことができ
る場合、スリーブは破れるか、または簡単にホースに加
わる圧着杷握力をゆるめて外れる可能性がある。Normally, nothing untoward occurs when fluid communicates through a fitting. However, if the fluid flow is reduced or stopped at some point upstream, the hydrostatic pressure within the fitting will strive to find a leak path. As is often the case,
If fluid is able to enter between the sleeve and the end of the hose, the sleeve can tear or easily loosen the crimp force on the hose and come off.
本発明の目的は、従来の管継手が経験する上述の問題金
主として除去する改良した高圧ホースおよび管継手を提
供することである。It is an object of the present invention to provide an improved high pressure hose and fitting that largely eliminates the above-mentioned problems experienced with conventional fittings.

いる。継手１６は、一端に第１のひだ付ホース受け肢１
ｇ、反対端にある第２の外部接続肢２０および２本の肢
１８と２０の中間にあるランド要素２２全備えている。As shown, the fitting 10 has a distal end 111i
The hose fitting 16 includes a portion of the hose 12 and a hose fitting 16. The fitting 16 has a first pleated hose receiving limb 1 at one end.
g, a second external connecting limb 20 at the opposite end and a land element 22 intermediate the two limbs 18 and 20.
スリーブ２ｑがホースの端ｌｉｔと肢１８の両方を囲い
、端１１ｉの上に圧着される。A sleeve 2q surrounds both the end lit and the limb 18 of the hose and is crimped over the end 11i.
ランド要素２２は平らなすなわち平面状の部分２６と該
部分２６の周縁部のまわシにある周壁２ｇとを備えてい

面状の部分２６とホース１２の端１４との間には、空所
３０が存在する。加圧された漏れ流体または浸出流体が
空所５０に達し。The land element 22 has a flat or planar portion 26 and a peripheral wall 2g around the periphery of the portion 26. The peripheral wall 2g is nested in the sleeve 211. A cavity 30 exists between the planar portion 26 and the end 14 of the hose 12. Pressurized leakage or seepage fluid reaches cavity 50.
ホースの端１４と周壁２８の間に入り込み１次にホース
の端ｉｌｌとスリーブ２４の間に入り込む場合、流体が
スリーブを破壊させるかまたはスリーブが外れるほどホ
ース上のスリーブ金ゆるくする可能性がある。If fluid enters between the hose end 14 and the sleeve 28 and then between the hose end 14 and the sleeve 24, the fluid can cause the sleeve to break or loosen the sleeve on the hose to the extent that it can be dislodged. .
本発明によれば１毛細穴５２は１周壁２ｇとスリーブ２
１１の両方を貫通して、蓄積された静流体圧をすべて逃
がす。毛細穴５２は、管継手の健全性を危険にさらさな
いために制御され、管理された漏れを与える。According to the present invention, one capillary hole 52 includes one peripheral wall 2g and a sleeve 2.
11 to release any accumulated hydrostatic pressure. Capillary holes 52 provide controlled and managed leakage so as not to jeopardize the integrity of the fitting.
本発明は以上に説明した構成をしているので。 The present invention has the configuration described above.
高圧ホースの上流で流体の流れが絞られたり止められた
りしても、継手部分に継手のスリーブを外したり破壊し
たりするような圧力の蓄積が生じないので、つねに継手
の健全性を保つので安全であり、実用上多大の効果があ
る。Even if fluid flow is constricted or stopped upstream of the high-pressure hose, the integrity of the fitting is maintained at all times because there is no pressure build-up in the fitting that could unsleeve or destroy the fitting. It is safe and has great practical effects.
