1230131 玖、發明說明： 【發明所屬之技術領域】 本發明係關於一種具有空氣式内胎之車輛（例如自行 車、摩托車、汽車、飛機等）、可以具備在車輛上之胎壓保 持系統、附内胎車輪及内胎用閥組件。 【先前技術】 例如在日本特開2 0 0 0 _ 3 3 5 4 7 1號公報（段落[0 0 0 5 ]、圖 1 )所揭示的，向來係知道在自行車呈一體地具備打氣用幫 浦者。這個係正如圖1 6所示，在鞍座1之支柱2下端部， 具備襯墊3，在插入該支柱2之自行車本體之管部4内， 襯墊3可自由地進行滑動。當連結於管部4下端部之軟管 5來結合於並未圖示之内胎閥之狀態下，如果一起上下移 動鞍座1和支柱2的話，則能夠供應壓縮空氣至内胎。 但是，在前述習知構造，存在所謂供應空氣至内胎之步 驟本身 ，並使，得内胎内壓，保持在良好狀態，因 此，頻繁地強化打氣步驟。此外，沒注意到内胎内壓降低 而駕駛車輛（自行車），也可能發生内胎過度變形之事件。 【發明内容】 本發明之目的，係提供一種能夠自動地供應壓縮空氣至 内胎之胎壓保持系統、附内胎車輪、車輛及内胎用閥組件。 按照本發明，在車輛行進時，以連動於車輪之旋轉，來 驅動幫浦，由幫浦而供應壓縮空氣至管路内。當内胎内壓 降低至通常狀態時，根據管路内壓和内胎内壓間之差而打 開止回閥，填充壓縮空氣至内胎内。然後，結束對於内胎 5 312/發明說明書(補件)/92-10/92121266 1230131 之壓縮空氣之填充，在管路内壓和内胎内壓間之差變 時，關閉止回閥。此外，在管路内壓成為既定值以上 打開溢流閥，釋放來自幫浦之壓縮空氣至外部。如此 照本發明，則能夠自動地供應壓縮空氣至内胎，並且 以開放所過剩供應之壓縮空氣，穩定胎壓。 【實施方式】 <第1實施例> 以下，根據圖1〜圖6而說明本發明之第1實施例 如圖1所示，在作為本發明車輛之自行車1 0所具備之 車輪1 1，於中心部，設置本發明之幫浦1 2。然後，在 1 2之外圍面和外嵌内胎1 3之軌道1 4間，插入複數個 幅1 5。 在圖2，顯示幫浦1 2之内部構造，該幫浦1 2係成/ 由所謂同步機構2 0而生成壓縮空氣之構造。具體地謂 備在幫浦1 2上之本發明之旋轉塊體2 1係成為兩端有 概略圓筒形構造，在旋轉塊體2 1之内部，收納圓筒形 架2 4。内殼架2 4係可自由旋轉地軸承在旋轉塊體2 1 端壁2 1 T，而成為接觸到旋轉塊體2 1内圍面一部分之 態。此外，旋轉塊體21之軸中心係配置在内殼架2 4 側，在該旋轉塊體21之軸中心，貫通車軸2 2。接著 軸22之兩端部係不可旋轉地固定在車輛10之本體上 自行車1 0行進時，以車軸2 2作為中心而使得旋轉塊 進行旋轉。 在車軸2 2，固定分隔突片2 3，該分隔突片2 3係貫 312/發明說明書(補件)/92-10/92121266 小 時， ，按 ，可 。正 前後 幫浦 轂輪 备藉 ,,具 底之 内殼 之兩 狀 之内 ，車 ，在 體21 通形 6 1230131 成在内殼架2 4周圍面上之縫隙2 4 S，碰觸到旋轉塊體2 1 之内圍面。然後，在車輪1 1旋轉時，分隔突片2 3係旋轉 在旋轉塊體2 1内，隨著這個而使得内殼架2 4，在旋轉塊 體21内，進行旋轉。然後，旋轉塊體21和内殼架2 4所包 圍之空間係藉由分隔突片2 3而劃分成為2個室1 2 K、1 2 K， 連動於車輪11之旋轉而擴縮各個室12K之容量。 在旋轉塊體2 1之周壁21 E，於夾住和内殼架2 4間之接 觸部分之兩側，設置吸引部2 5和排出部2 6。然後，在車 輪1 1沿著圖2之逆時針旋轉方向而進行旋轉時，由吸引部 2 5所吸引至室1 2 K内之空氣係成為壓縮空氣而由排出部 2 6，來進行排出。 在排出部2 6，具備由周壁2 1 E開始突出之筒壁2 7，在該 筒壁27之前端，扭轉進管接頭28。正如圖2所示，在管 接頭28，固定管29之某一端，該管29之其他端係延長於 車輪1 1之軌道14側而固定在内胎用閥組件3 0 (以下、僅 稱為「闊組件3 0」）。然後，由這些幫浦1 2之排出部2 6、 闊組件3 0和管2 9而構成本發明之胎壓保持系統3 1。 在圖3，顯示閥組件3 0。具備在閥組件3 0之本發明之管 桿3 2係成為軸狀，通過在軌道1 4所形成之貫通孔1 4 A， 在該管桿3 2基端部之外側，密合及固定内胎1 3(參照圖2 ) 内之内胎管1 3 C。藉此而使得貫通管桿3 2軸心部之空間 3 2 A，能夠連通至内胎1 3之内部空間1 3 A (詳細地說、内 胎管1 3 C之内部空間）。更加詳細地說，管桿3 2係由密合 及固定在内胎管1 3 C之基礎管桿3 3和螺合及組裝在該基礎 7 312/發明說明書(補件)/92· 10/92121266 1230131 管桿3 3外面之延長管桿3 4所構成。此外，在基礎管桿3 3 之外面，螺合及固定例如圓板零件3 5，在該圓板零件3 5 和延長管桿3 4間，夾住車輪1 1之執道1 4之貫通孔1 4 A 之邊緣部，藉此而使得管桿3 2，固定在由執道1 4開始朝 向幫浦1 2來進行豎立之狀態。 在管桿3 2内，由内胎1 3側開始，依序地設置内閥4 0 和溢流闊6 5。内閥4 0係正如圖5所示，在插通於筒體6 0 之軸61之某一端側，固定及具備凸緣狀橡膠栓6 2 (相當 於本發明之「止回閥用蓋體」）。此外，藉由利用收納在筒 體6 0内之作為「止回閥用致能裝置」之線圈彈簧6 3而使 得軸6 1致能在某一邊側，以便於一直將橡膠栓6 2，擠壓 在筒體6 0之某一端開口 ，成為内閥4 0關閉之狀態（參照 圖5 )。然後，正如圖6所示，在軸61抵抗於線圈彈簧6 3 而進行移動時，橡膠栓6 2係由筒體6 0離開，可以打開内 閥4 0而使得空氣通過該内閥4 0内。 正如圖3所示，溢流閥6 5係在延長管桿3 4内，成為可 進行直動之軸狀，在離開内闊4 0側之端部，具備凸緣6 7。 由凸緣6 7之外緣部開始，朝向内閥4 0而突出周壁6 8，在 該周壁6 8之内側，收納圓板狀密封構件6 9。另一方面， 在延長管桿34之内面，形成段附部34D，在該段附部34D 之内緣部，朝向離開内閥4 0之側而突出圓形突狀7 0。此 外，在溢流閥6 5之凸緣6 7和延長管桿3 4之前端壁3 4 S 間，線圈彈簧7 1係收納成為壓縮變形之狀態，藉由線圈彈 簧7 1之爆發力而使得溢流閥6 5之密封構件6 9，擠壓在圓 8 312/發明說明書(補件)/92-10/92121266 1230131 形突狀70上。 在藉由管桿3 2内之空間3 2 A中之溢流閥6 5之密封 6 9和圓形突狀7 0間之密合而隔絕於内閥4 0之釋放室 3 2 C，形成釋放孔7 3。釋放孔7 3係貫通及形成在延長 3 4中之圓形突狀7 0附近之側壁上。 在管桿3 2内之空間3 2 A中之溢流閥6 5之密封構件 和圓形突狀7 0間之密合部分以及内闊4 0所夾住之裝 3 2 B，形成空氣供應孔7 2。空氣供應孔7 2係貫通及形 延長管桿3 4之側壁上，在此，連結由幫浦1 2開始延 管2 9之端部。然後，藉由幫浦1 2之排出部2 6、管桿 和管2 9而構成本發明之管路7 4 (參照圖2 )。 溢流閥6 5之某一端係擠壓在内閥4 0之軸6 1。這些 閥6 5和軸6 1係致能在藉由前述線圈彈簧6 3、7 1所互 壓之方向上，因此，在實質上，成為連結溢流閥6 5禾 6 1之狀態。藉此而使得内閥4 0和溢流閥6 5進行連動 作。 其次，說明由前述構造所構成之本實施例之動作。 在自行車1 0停車時，停止幫浦1 2。此時，在閥組件 成為關閉内閥4 0並且打開溢流闊6 5之狀態。 在自行車1 0行進時，以連動於車輪1 1之旋轉來驅 浦1 2，由幫浦1 2開始，通過管2 9，填充壓縮空氣至 件3 0之裝料室3 2 B。如此，壓縮空氣之一部分係通過 閥6 5而由釋放孔7 3洩漏，但是，在自行車以既定速 上而行進時，使得來自幫浦1 2之供應量，更加多於來 312/發明說明書(補件)/92-10/92121266 構件 管桿 69 料室 成在 伸之 32 溢流 相擠 ，軸 及動 30， 動幫 閥組 溢流 度以 自釋 9 1230131 放孔7 3之洩漏量，使得裝料室3 2 B之内壓上升。此時，在 内胎1 3之内壓（詳細地說、内胎管1 3 C之内壓）降低至通 常狀態時，根據裝料室3 2 B之内壓和内胎1 3之内壓間之差 而打開内閥4 0。如此，連動於此而關閉溢流閥6 5，將來自 幫浦1 2之壓縮空氣，填充至内胎1 3内。 然後，在藉由壓縮空氣之填充而使得内胎1 3之内壓上 升時，關閉内閥4 0，並且，連動於此而打開溢流閥6 5，將 來自幫浦1 2之壓縮空氣，釋放至閥組件3 0之外部。 如此，按照本實施例之自行車1 0的話，則能夠自動地 供應壓縮空氣至内胎1 3，可以穩定内胎1 3之内壓。此外， 在本實施例之自行車1 0，連結内閥4 0和溢流閥6 5，在關 閉内閥4 0間，保持在溢流閥6 5打開之狀態，因此，將來 自幫浦1 2之多餘之壓縮空氣，順暢地釋放至外部。藉此而 減低車輪1 1之旋轉抵抗。此外，在本實施例之胎壓保持系 統3 1，能夠分解成為幫浦1 2、閥組件3 0和連繫這些之管 29，因此，可以對於尺寸不同之車輪11而使得管29之長 度呈不同，來進行對應，同時，能夠在尺寸不同之車輪11 間，達到幫浦1 2和閥組件3 0之共通化。 <第2實施例> 本實施例之閥組件3 0 V係顯示在圖7及圖8，僅溢流閥 6 5 V之構造不同於前述第1實施例。具備在本實施例之閥 組件3 0 V之溢流閥6 5 V係軸長更加短於前述第1實施例之 溢流閥6 5，藉此而成為不接觸到内閥4 0之軸6 1之構造。 此外，前述第1實施例之密封構件6 9 V係成為可以將剖面 10 312/發明說明書(補件)/92-10/92121266 1230131 圓形之橡膠管嵌合在周壁6 8内側之環狀。 此外，除了前面敘述以外，基本構造係共通於前述第1 實施例，關於這些共通之構造之必要部位，藉由在圖7及 圖8，附加相同於第1實施例之同樣符號，而省略重複之 說明。 本實施例之闊組件3 0係如以下而進行作用。 在由於自行車1 0之停車而停止幫浦1 2時，關閉内閥4 0 和溢流閥6 5兩者（參照圖7 )。 在自行車1 0行進時，驅動幫浦1 2，填充壓縮空氣至閥 組件3 0之裝料室3 2 B。此時，在内胎1 3之内壓低於通常 狀態時，根據裝料室3 2 B之内壓和内胎1 3之内壓間之差而 打開内閥4 0，將壓縮空氣填充至内胎1 3内。 在内胎1 3之内壓成為通常狀態之壓力時，關閉内閥4 0。 在該狀態下，在藉由來自幫浦1 2之壓縮空氣而使得裝料室 3 2 B之内壓上升時，打開溢流閥6 5 V，將多餘之壓縮空氣， 釋放至閥組件3 0 V之外部（參照圖8 )。 <第3實施例> 本實施例之閥組件3 0 W係顯示在圖9，改變第2實施例。 以下，僅關於和第1及第2之各個實施例之不同構造而進 行說明，關於共通於各個實施例之構造，則藉由附加相同 符號，而省略重複之說明。 在本實施例之閥組件3 0 W，於管桿3 2中之溢流閥6 5和 内閥4 0間，設置中間閥8 0。該中間閥8 0係在直動於管路 7 4内之軸體8 1，以重疊圓板形密封構件8 2和限制板8 3 11 312/發明說明書(補件)/92-10/92121266 1230131 之狀態，來進行外嵌固定。 圓板形密封構件8 2係例如藉由橡膠板所構成，按 側開始而朝向外緣部，成為進行彎曲而朝向内閥4 0 逼出之構造，其外緣部係密合在管路7 4之周圍面 限制板8 3係例如藉由金屬板所構成，對應於圓板 構件8 2，按照由内側開始而朝向外緣部，進行彎曲 内閥4 0來進行逼出，限制圓板形密封構件8 2在相 閥4 0之相反側來進行彈性變形，另一方面，容許對 4 0側之彈性變形。此外，中間閥8 0係可以在管路 進行直動，此外，藉由線圈彈簧8 4而致能於内閥 此外，在本實施例，釋放孔7 3係形成在延長管？ 前端壁3 4 S，在溢流閥6 5 V離開圓形突狀7 0時，壓 係通過溢流閥6 5 V和延長管桿3 4之内圍面間之間丨 放孔73而釋放至外部。 在本實施例之閥組件3 0 W，於由内閥4 0側而洩漏 狀態下，中間閥8 0中之圓板形密封構件8 2之内閥 壓力變高，中間閥8 0係抵抗於線圈彈簧8 4而移動 内閥4 0之側，同時，圓板形密封構件8 2係沿著相 曲之方向而進行變形，擴張至外側，圓板形密封構 之外緣部係密合在管桿3 2之内面，防止内胎1 3内 由中間閥8 0洩漏至外側。 此外，由幫浦1 2而填充壓縮空氣至裝料室3 2 B， 於圓板形密封構件8 2之内閥4 0之相反側之壓力變 圓板形密封構件8 2係可以沿著彎曲變深之方向而3 312/發明說明書(補件)/92-10/92121266 照由内 來進行 〇 形密封 而朝向 反於内 於内閥 74内，

如此，在實施例之閥組件3 0 W，藉由内閥4 0和中間閥8 0 兩者而限制來自内胎1 3之空氣洩漏，在内胎1 3之内壓降 低時，可以通過這些内閥4 0和中間闊8 0而填充空氣至内 胎1 3内。 <第4實施例> 本實施例之閥組件3 0 X係顯示在圖1 0，改變第3實施 例。以下，僅關於和第1〜第3之各個實施例之不同構造 而進行說明，關於共通於各個實施例之構造，則藉由附加 相同符號，而省略重複之說明。 在本實施例之閥組件3 0 X之管桿3 2 X，將内閥4 0和中間 閥8 0排列在同軸上而收納之第1空間8 6係在管桿3 2 X開 放於前端而成為空氣供應孔72。接著，在螺合於該空氣供 應孔7 2之管接頭8 5，連結來自幫浦1 2之管2 9。 此外，在管桿3 2 X，形成第2空間8 7而並聯於第1空間 8 6，在該第2空間8 7之内部，收納溢流閥6 5 V。此外，由 第1空間8 6中之中間閥8 0開始，空氣供應孔7 2側之室和 第2空間8 7中之夾住溢流閥6 5 V而相反於釋放孔7 3之相 反側之室係藉由橫孔而進行連通。即使是這樣構成，也達 到相同於第1〜第3之各個實施例之同樣之作用效果。 13 312/發明說明書(補件)/92-10/92121266 1230131 <第5實施例> 本實施例之閥組件3 0 X係顯示在圖1 1，改變第4實施 例。以下，僅關於和第1〜第4之各個實施例之不同構造 而進行說明，關於共通於各個實施例之構造，則藉由附加 相同符號，而省略重複之說明。 在本實施例之閥組件3 0 Y之管桿3 2 Y，在和内閥4 0延伸 於同軸上之第1空間8 6之前端側，設置第2内閥8 9，使 得管桿3 2 Y之前端，成為本發明之外部幫浦裝設部1 0 0。 在該外部幫浦裝設部1 0 0，螺合帽蓋1 0 2。此外，第2内闊 8 9係基本構造相同於内閥4 0。 此外，空氣供應孔7 2係配置在第2内閥8 9和中間闊8 0 間，連通於第1空間8 6，在螺合於該空氣供應孔7 2之管 接頭1 01，連結來自幫浦1 2之管2 9。 按照本實施例之閥組件3 0 Y的話，則可以達到相同於前 述第1〜第3之各個實施例之同樣之作用效果，同時，藉 由在外部幫浦裝設部1 0 0，裝設外部幫浦，而配合必要， 利用外部幫浦，來填充空氣至内胎1 3内。 <第6實施例> 本實施例之胎壓保持系統3 1 Z係顯示在圖1 2，改變第4 實施例。以下，僅關於和第1〜第5之各個實施例之不同 構造而進行說明，關於共通於各個實施例之構造，則藉由 附加相同符號，而省略重複之說明。本實施例之閥組件3 0 Z 係成為將第4實施例之閥組件3 0 X之溢流閥6 5 V呈一體地 設置在幫浦1 2之排出部2 6之構造。更加具體地說，另外 14 312/發明說明書(補件)/92-10/92121266 1230131 不同於排出部26之筒壁27所具備之排出口 27A，還在筒 壁2 7，形成橫孔2 7 B，成為在該橫孔2 7 B之内部具備溢流 閥6 5 V之構造。 正如本實施例，可以藉由將溢流閥6 5 V固定在幫浦1 2， 而將溢流閥6 5 V配置在車輪之旋轉中心側，比起設置在車 輪外緣部之狀態，還更加能夠減低由於溢流閥6 5 V所造成 之慣性（慣性動量）。 <第7實施例> 本實施例係顯示在圖1 3〜圖1 5，幫浦之構造係不同於 第1實施例。本實施例之幫浦1 2 V係成為藉由所謂曲軸滑 件機構2 0 V而生成壓縮空氣之構造。具體地說，幫浦1 2 V 之旋轉塊體2 1 V係成為由圓筒體9 0之側面開始而延設氣缸 91之構造，該圓筒體90係配置在車輪（並無顯示在圖13 〜圖1 5。參照圖1 )之中心，同時，在圓筒體9 0之周圍面，

vehicle having an air tube (such as a bicycle, a motorcycle, a car, an airplane, etc.), which can be provided with a tire pressure maintaining system on the vehicle, and includes a tube Valve assembly for wheels and inner tubes. [Prior Art] For example, as disclosed in Japanese Patent Application Laid-Open No. 2 0 0 0 _ 3 3 5 4 7 1 (paragraph [0 0 0 5], FIG. 1), it has been known that a bicycle is integrally provided with a pumping aid. Puzhe. As shown in FIG. 16, this system is provided with a cushion 3 at the lower end portion of the pillar 2 of the saddle 1. The cushion 3 can slide freely in the tube portion 4 of the bicycle body inserted into the pillar 2. When the hose 5 connected to the lower end of the tube portion 4 is coupled to a tube valve (not shown), if the saddle 1 and the support 2 are moved up and down together, compressed air can be supplied to the tube. However, in the aforementioned conventional structure, there is a so-called step of supplying air to the inner tube itself, and the inner pressure of the inner tube is maintained to be in a good state. Therefore, the pumping step is frequently strengthened. In addition, if you do not notice the decrease in the inner tube pressure and drive a vehicle (bicycle), excessive tube deformation may occur. SUMMARY OF THE INVENTION An object of the present invention is to provide a tire pressure maintaining system capable of automatically supplying compressed air to an inner tube, a wheel with a tube, a valve assembly for a vehicle, and a tube. According to the present invention, when the vehicle is traveling, the pump is driven in conjunction with the rotation of the wheels, and the pump supplies compressed air into the pipeline. When the inner pressure of the inner tube is reduced to the normal state, the check valve is opened according to the difference between the inner pressure of the tube and the inner pressure of the inner tube, and the compressed air is filled into the inner tube. Then, the filling of the compressed air for the inner tube 5 312 / Invention Specification (Supplement) / 92-10 / 92121266 1230131 is finished, and the check valve is closed when the difference between the inner pressure of the pipe and the inner pressure of the inner tube changes. In addition, open the relief valve when the internal pressure of the pipeline becomes higher than the predetermined value, and release the compressed air from the pump to the outside. In this way, according to the present invention, compressed air can be automatically supplied to the inner tube, and the excessively supplied compressed air is opened to stabilize the tire pressure.

At the peripheral wall 21 E of the rotary block 21, on both sides of the contact portion between the sandwiched block and the inner housing frame 24, a suction portion 25 and a discharge portion 26 are provided. Then, when the wheel 11 is rotated counterclockwise in FIG. 2, the air sucked into the chamber 12K by the suction portion 25 becomes compressed air and is discharged by the discharge portion 26. The discharge portion 26 is provided with a cylinder wall 27 which protrudes from the peripheral wall 2 1E, and the pipe joint 28 is twisted at the front end of the cylinder wall 27. As shown in FIG. 2, at the pipe joint 28, one end of the fixed pipe 29 is fixed, and the other end of the pipe 29 is extended to the track 14 side of the wheel 11 to be fixed to the valve assembly 30 for the inner tube (hereinafter, simply referred to as " Wide component 3 0 ″). Then, the exhaust portion 26 of the pump 12, the wide unit 30, and the pipe 29 constitute the tire pressure maintaining system 31 of the present invention. In Figure 3, the valve assembly 30 is shown. The stem 32 of the present invention, which is provided at the valve assembly 30, is formed into a shaft shape. Through a through hole 14A formed in the rail 14, a tube is tightly attached and fixed to the outer side of the stem end of the stem 32. 1 3 (refer to Figure 2) inner tube 1 3 C. As a result, the space 3 2 A penetrating the shaft center portion of the stem 32 can be communicated to the inner space 1 3 A of the inner tube 1 3 (more specifically, the inner space of the inner tube 1 3 C). In more detail, the stem 3 2 is a base stem 3 3 which is tightly attached and fixed to the inner tube 1 3 C, and is screwed and assembled on the foundation 7 312 / Invention Specification (Supplement) / 92 · 10/92121266 1230131 Pipe rod 3 3 is formed by an extension tube 34. In addition, on the outer surface of the base pipe rod 3 3, for example, a circular plate member 35 is screwed and fixed. Between the circular plate member 3 5 and the extension pipe rod 3 4, the through hole of the guideway 14 of the wheel 11 is sandwiched. The edge portion of 1 4 A is thereby used to fix the pipe 3 2 in a state where it is erected from the channel 14 to the pump 12. In the pipe rod 32, starting from the inner tube 13 side, an inner valve 40 and an overflow valve 65 are sequentially provided. The inner valve 4 0 is as shown in FIG. 5, and is fixed and provided with a flange-shaped rubber plug 6 2 (corresponding to the “check valve cover” of the present invention) on one end side of the shaft 61 inserted into the cylinder 60. "). In addition, the shaft 61 is enabled on one side by using the coil spring 63 as the "enable device for the check valve" housed in the cylinder 60, so that the rubber plug 62 can be squeezed all the time. Press on one end of the cylinder 60 to open, and the inner valve 40 is closed (refer to FIG. 5). Then, as shown in FIG. 6, when the shaft 61 moves against the coil spring 63, the rubber stopper 62 is separated from the cylinder 60, and the inner valve 40 can be opened to allow air to pass through the inner valve 40. . As shown in Fig. 3, the relief valve 65 is formed in the extension pipe rod 34 and has a shaft shape capable of performing direct movement. The flange portion 6 7 is provided at an end portion away from the inner width 40 side. Starting from the outer edge of the flange 67, the peripheral wall 68 is projected toward the inner valve 40. Inside the peripheral wall 68, a disc-shaped sealing member 69 is housed. On the other hand, a segment attachment portion 34D is formed on the inner surface of the extension pipe rod 34, and the inner edge portion of the segment attachment portion 34D protrudes toward the side away from the inner valve 40 and protrudes into a circular protrusion 70. In addition, between the flange 6 7 of the relief valve 65 and the end wall 3 4 S before the extension pipe rod 3 4, the coil spring 7 1 is accommodated in a state of compression deformation, and the overflow is caused by the explosive force of the coil spring 7 1. The sealing member 6 9 of the flow valve 65 is extruded on the circle 70 312 / Invention Specification (Supplement) / 92-10 / 92121266 1230131. The release chamber 3 2 C of the inner valve 40 is sealed by the tight seal between the seal 6 9 of the relief valve 6 5 in the space 3 2 A in the pipe rod 3 2 and the round protrusion 70, and is formed. Release hole 7 3. The release hole 7 3 penetrates and is formed on the side wall near the circular protrusion 70 in the extension 34. The sealing member of the relief valve 65 in the space 3 2 A in the pipe rod 3 2 and the tight part between the circular projection 70 and the mounting 3 2 B sandwiched by the inner width 40 form an air supply. Hole 7 2. The air supply hole 7 2 extends through the side wall of the elongated pipe rod 34, and here, the ends of the pipe 29 extending from the pump 12 are connected. Then, the discharge section 26 of the pump 12, the pipe rod, and the pipe 29 constitute the pipe 7 4 of the present invention (see FIG. 2). One end of the relief valve 65 is extruded on the shaft 61 of the inner valve 40. These valves 65 and the shaft 61 are in a direction of mutual pressure by the coil springs 6 3 and 7 1, and therefore, they are substantially connected to the overflow valves 6 5 and 61. As a result, the inner valve 40 and the relief valve 65 are interlocked. Next, the operation of this embodiment constituted by the aforementioned structure will be described. Stop the pump 12 when the bicycle 10 stops. At this time, the valve assembly is in a state in which the inner valve 40 is closed and the overflow valve 65 is opened. When the bicycle 10 travels, the pump 12 is driven in conjunction with the rotation of the wheel 11 starting from the pump 12 and filled with compressed air through the pipe 29 to the charging chamber 3 2B of the 30. In this way, part of the compressed air leaks through the release hole 73 through the valve 65, but when the bicycle is traveling at a predetermined speed, the supply from the pump 12 is more than that from 312 / Invention Specification ( (Supplement) / 92-10 / 92121266 Component pipe rod 69 The material chamber is squeezed into the overflow of 32, the shaft and the moving 30, the overflow degree of the dynamic help valve group is self-releasing 9 1230131 and the leakage of the hole 7 3 makes The internal pressure of the charging chamber 3 2 B rises. At this time, when the inner pressure of the inner tube 1 3 (specifically, the inner pressure of the inner tube 1 3 C) is reduced to a normal state, the difference between the inner pressure of the charging chamber 3 2 B and the inner pressure of the inner tube 13 is reduced. And open the inner valve 4 0. In this way, in conjunction with this, the relief valve 65 is closed, and the compressed air from the pump 12 is filled into the inner tube 13. Then, when the inner pressure of the inner tube 13 is increased by the filling of the compressed air, the inner valve 40 is closed and the relief valve 65 is opened in conjunction with this to release the compressed air from the pump 12 To the outside of the valve assembly 30. As described above, according to the bicycle 10 of this embodiment, compressed air can be automatically supplied to the inner tube 13 and the inner pressure of the inner tube 13 can be stabilized. In addition, in the bicycle 10 of this embodiment, the inner valve 40 and the relief valve 65 are connected, and the inner valve 40 is closed, and the relief valve 65 is kept open. Therefore, it will be from the pump 12 The excess compressed air is smoothly released to the outside. This reduces the rotation resistance of the wheels 11. In addition, the tire pressure maintaining system 31 in this embodiment can be decomposed into a pump 12, a valve assembly 30, and a tube 29 connected to these. Therefore, the length of the tube 29 can be made for wheels 11 having different sizes.
