The 231 barriers are not connected to each other, and the oil and gas in the oil tank 137 cannot enter the second portion 36B of the installation space 36 from the tank port 151 through the passage 37, and the outside air cannot enter the installation through the oil and gas filtering device 157 and the conduit 155. In the first portion 36A of the space 36, in other words, in a state where the first valve 213 is in the closed position and the second valve 231 is in the closed position, there is no airflow between the inside of the oil tank 137 and the atmosphere, and the fuel tank 137 It is completely closed.
所述油箱137內部的壓力會隨著氣溫變化或使用情況不同而產生有變化,例如當氣溫升高時,油箱137內部的壓力會隨著升高,或者當油箱137內部的燃料消耗時,油箱137的內部就會產生負壓。假設氣溫升高使得油箱137內部的壓力升高,由於第二閥片231覆蓋第一部份36A(如第5圖所示),因此油箱137內部的壓力會通過通道37傳遞至第二閥 片231上,當油箱137內部的壓力大至高於第二彈簧237的彈力時,第二閥片231會由封閉第一部份36A的關閉位置壓縮第二彈簧237位移至非關閉位置(如第7圖所示),如此第一部份36A與第二部份36B連通,進一步油箱137內部的壓力(油氣)經由通道37、第一部份36A進入第二部份36B內,並且進一步經由排氣孔98與導管155導向所述油氣過濾設備157,所述油氣經油氣過濾設備157過濾之後才排放至大氣中,直至油箱137內部的壓力降低至小於第二彈簧237的彈力時,第二彈簧237偏壓第二閥片231復位至關閉位置。 The pressure inside the oil tank 137 may change depending on the temperature change or usage, for example, when the temperature rises, the pressure inside the oil tank 137 may increase, or when the fuel inside the oil tank 137 is consumed, the fuel tank Negative pressure is generated inside the 137. Assuming that the temperature rises so that the pressure inside the oil tank 137 rises, since the second valve piece 231 covers the first portion 36A (as shown in Fig. 5), the pressure inside the oil tank 137 is transmitted to the second valve through the passage 37. On the piece 231, when the pressure inside the oil tank 137 is much higher than the elastic force of the second spring 237, the second valve piece 231 is compressed by the closed position of the closed first portion 36A to be displaced to the non-closed position (such as 7 is shown), so that the first portion 36A is in communication with the second portion 36B, and further the pressure (oil and gas) inside the fuel tank 137 enters the second portion 36B via the passage 37, the first portion 36A, and further passes through the row. The air hole 98 and the conduit 155 are guided to the oil and gas filtering device 157, and the oil and gas is filtered by the oil and gas filtering device 157 before being discharged into the atmosphere until the pressure inside the oil tank 137 is reduced to be smaller than the elastic force of the second spring 237, the second spring The 237 biased second valve plate 231 is reset to the closed position.
假設油箱137內部燃料隨著使用造成油箱137內部產生負壓,當所述負壓大於第一彈簧217的彈力時,所述第一閥片213受到大氣壓力擠壓而壓縮第一彈簧217由封閉位置(如第5圖所示)位移至非封閉位置(如第8圖所示),造成第二閥片231上的通孔233被開放,並且所述第二閥片231被第二彈簧237偏置在關閉位置上,在這個狀態下由於油箱137內部是負壓狀態,因此油箱137外部的壓力大於油箱137內部的壓力,所以只會造成大氣中的空氣通過油氣過濾設備157後經由導管155輸送到安裝空間36中進一步透過通道37與加油口32進入到油箱137內,直至油箱137內部的壓力從負壓恢復至與大氣壓力相同或接近,所述第一彈簧217偏壓第一閥片213與第一墊片215一起復位至封閉位置(如第5圖所示)。 It is assumed that the internal fuel of the fuel tank 137 causes a negative pressure inside the oil tank 137 as the use, and when the negative pressure is greater than the elastic force of the first spring 217, the first valve piece 213 is pressed by the atmospheric pressure to compress the first spring 217 to be closed. The position (as shown in Fig. 5) is displaced to the non-closed position (as shown in Fig. 8), causing the through hole 233 on the second valve piece 231 to be opened, and the second valve piece 231 is replaced by the second spring 237. The bias is in the closed position. In this state, since the inside of the oil tank 137 is in a negative pressure state, the pressure outside the oil tank 137 is greater than the pressure inside the oil tank 137, so that only the air in the atmosphere passes through the oil and gas filtering device 157 via the conduit 155. The first spring 217 is biased into the installation space 36 and further penetrates into the oil tank 137 through the passage 37 and the fuel filler port 32 until the pressure inside the oil tank 137 recovers from the negative pressure to be the same as or close to the atmospheric pressure, and the first spring 217 biases the first valve piece. 213 is reset to the closed position with the first shim 215 (as shown in Figure 5).
若要將油箱蓋體46操作為不被鎖定的狀態,則是操作所述主開關鎖拉動鋼索使得拉柄175樞轉,進一步拉柄175驅動卡合件159由卡合位置位移至非卡合位置,如此卡合件159的卡合端171脫離油箱蓋體 46的卡鉤66,如此油箱蓋體46就不被卡合件159鎖定,因而可以相對承座20樞轉油箱蓋體46遠離頸部26,進一步加油口32與油箱口151開放,如此可以通過加油口32與油箱口151添加燃料。 To operate the fuel tank cover 46 in an unlocked state, the main switch lock is operated to pull the cable so that the handle 175 pivots, and the further handle 175 drives the engaging member 159 to be displaced from the engaged position to the non-engaged position. Position, such that the engaging end 171 of the engaging member 159 is disengaged from the fuel tank cover The hook 66 of the 46, so that the fuel tank cover 46 is not locked by the engaging member 159, so that the fuel tank cover 46 can be pivoted away from the neck 26 relative to the socket 20, and the further oil filling port 32 and the oil tank opening 151 are opened, so that The fuel filler port 32 and the fuel tank port 151 add fuel.
本發明的油箱蓋裝置10透過第一單向閥裝置211控制油箱蓋裝置10外部的空氣能否進入油箱137中,並且透過第二單向閥裝置219控制油箱137內部的油氣可否被排出油箱137外,藉此得以控制油箱137內部的壓力值在較適當的作業範圍內,並同時兼具防止油箱137內的燃油外漏的效果。 The fuel tank cap device 10 of the present invention controls whether the air outside the fuel tank cap device 10 can enter the oil tank 137 through the first check valve device 211, and controls whether the oil and gas inside the oil tank 137 can be discharged into the oil tank 137 through the second check valve device 219. In addition, it is thereby possible to control the pressure value inside the oil tank 137 within a relatively appropriate working range, and at the same time, to prevent the fuel from leaking out of the oil tank 137.
本發明將控制可否進氣的第一單向閥裝置211以及空置可否排氣的第二單向閥裝置219都安裝在隱藏於車輛內部的承座20上(例如內藏在摩托車的車殼內側),能夠順利的在油箱內部產生過大負壓時將外部空氣導入油箱137內平衡壓力,使得與油氣過濾設備157連接的導管155可以隱藏在內部,降低導管155損壞的機率。 The present invention mounts the first check valve device 211 that controls the availability of intake air and the second check valve device 219 that is vacant or not ventilated on the seat 20 hidden inside the vehicle (for example, a car body built in a motorcycle) The inner side can smoothly introduce the outside air into the balance pressure in the oil tank 137 when an excessive negative pressure is generated inside the fuel tank, so that the duct 155 connected to the oil and gas filtering device 157 can be hidden inside, reducing the probability of damage of the duct 155.
本發明的基本教導已加以說明,對具有本領域通常技能的人而言,許多延伸和變化將是顯而易知者。舉例言之,油箱蓋裝置10可以不包括上鎖機構158,所述油箱蓋體46可以不包括樞接臂68,如此所述油箱蓋體46外表面以及承座20內表面可以設置相互配合的螺紋,使得油箱蓋體46可以與承座20螺設封閉加油口32。 The basic teachings of the present invention have been described, and many extensions and variations will be apparent to those of ordinary skill in the art. For example, the fuel tank cap device 10 may not include the locking mechanism 158, and the fuel tank cap 46 may not include the pivoting arm 68, such that the outer surface of the fuel tank cap 46 and the inner surface of the socket 20 may be disposed to cooperate with each other. The thread is such that the fuel tank cap 46 can be screwed to the socket 20 to close the fuel filler opening 32.
