While the hydraulic control device 10 is illustrated with the hydraulic sump 12 disposed between a bracket member 14 and a tie rod 16 , it should be understood that the hydraulic sump 12 may be otherwise positioned on the hydraulic control device 10 . For example, the hydraulic tank 12 may be arranged in line with the tie rods 16 .

液壓槽12具有一空氣通道18。如第三圖所示，空氣通道18包括一第一部分18a及一第二部分18b。第一部分18a沿著一第一方向D1延伸，並且第二部分18b沿著不同於該第一方向D1的一第二方向D2延伸。如第六圖所示，該第一方向D1和該第二方向D2彼此垂直。或者，該第一方向D1和該第二方向D2可非垂直。 The hydraulic tank 12 has an air passage 18 . As shown in the third figure, the air passage 18 includes a first portion 18a and a second portion 18b. The first portion 18a extends along a first direction D1, and the second portion 18b extends along a second direction D2 different from the first direction D1. As shown in the sixth figure, the first direction D1 and the second direction D2 are perpendicular to each other. Alternatively, the first direction D1 and the second direction D2 may not be perpendicular.

如第六圖至第八圖所示，液壓槽12包括一油槽22、其部分剖面圖由第八圖的虛線所指示。油槽22具有一槽開口24及附接至槽開口24的一蓋子25。 如第六圖所示，空氣通道18至少部分位於蓋子25內。第五圖顯示蓋子25的一具體實施例之正視圖，並且第六圖提供第五圖中蓋子25的部分剖面圖，以例示蓋子25如何裝入油槽22，其係以虛線表示。本說明書內說明的任何具體實施例都包括一緊固件26，其用以穿過油槽22將蓋子25固定其中，如第九圖至第十二圖所示。 As shown in FIGS. 6 to 8, the hydraulic tank 12 includes an oil tank 22, a partial cross-sectional view of which is indicated by the dotted line in the eighth diagram. The oil sump 22 has a sump opening 24 and a cover 25 attached to the sump opening 24 . As shown in the sixth figure, the air channel 18 is located at least partially within the cover 25 . Figure 5 shows a front view of one embodiment of the cover 25, and Figure 6 provides a partial cross-sectional view of the cover 25 in Figure 5 to illustrate how the cover 25 fits into the sump 22, shown in phantom. Any specific embodiment described in this specification includes a fastener 26 for passing through the oil groove 22 to secure the cover 25 therein, as shown in FIGS. 9-12.

油槽22更包括一內表面22a與一外表面22b。一隔板28位於油槽22內。隔板28配置在槽開口24旁邊，並且蓋子25用以***槽開口24而同時接觸油槽22的內表面22a與隔板28。如第七圖和第八圖所示，在例示的具體實施例，液壓槽12界定在油槽22與隔板28之間的一流體腔室30。此外，請即參考第六圖，液壓槽12界定在隔板28與蓋子25之間的一空氣腔室32。空氣通道18讓液壓槽12的空氣腔室32連通至外界。隔板28具有袋狀，並且由像是橡膠這類彈性材料製成。利用允許空氣通過空氣通道18在空氣腔室32與外界之間自由移動，則通過隔板28所界定的空氣腔室32可適應液壓槽12內流體腔室30之體積變化。如第六圖虛線所示，隔板28配置在蓋子25旁邊。在這種組態中，隔板28將油槽22內的流體腔室30與空氣腔室32隔開，其一部分由第六圖的虛線所示。 The oil groove 22 further includes an inner surface 22a and an outer surface 22b. A baffle 28 is located within the oil sump 22 . The spacer 28 is disposed beside the groove opening 24 , and the cover 25 is used to be inserted into the groove opening 24 while contacting the inner surface 22 a of the oil groove 22 and the spacer 28 . As shown in Figures 7 and 8, in the illustrated embodiment, the hydraulic sump 12 defines a fluid chamber 30 between the oil sump 22 and the diaphragm 28 . In addition, please refer to FIG. 6 , the hydraulic tank 12 defines an air chamber 32 between the diaphragm 28 and the cover 25 . The air passage 18 communicates the air chamber 32 of the hydraulic tank 12 to the outside world. The separator 28 has a bag shape and is made of an elastic material such as rubber. By allowing air to move freely between the air chamber 32 and the outside world through the air passage 18 , the air chamber 32 defined by the baffle 28 can accommodate changes in the volume of the fluid chamber 30 within the hydraulic tank 12 . As shown by the dotted line in FIG. 6 , the partition plate 28 is arranged beside the cover 25 . In this configuration, the baffle 28 separates the fluid chamber 30 from the air chamber 32 within the oil sump 22, a portion of which is shown in phantom in the sixth figure.

請即重新參考第六圖，空氣通道18用以讓空氣腔室32與外界接觸。如上面簡單討論，將空氣腔室32與流體腔室30分隔的隔板28隨使用者或騎士操縱液壓控制裝置10而變形，從而改變空氣腔室32的體積。此移動可增加或減少空氣腔室32內的空氣壓力。將空氣腔室32連接至外界可以使用隔板28移動造成的空氣壓力變化相等。此外，空氣通道18包括面對外界的一通道開口34。此特徵有助於直接接觸外界，從而簡化空氣腔室32與外界之間氣流的路徑。液壓控制裝置10用以通道開口34界定在油槽22與蓋子25之間，如第六圖所示。 Please refer to FIG. 6 again, the air passage 18 is used for the air chamber 32 to be in contact with the outside world. As discussed briefly above, the partition 28 separating the air chamber 32 from the fluid chamber 30 deforms as the user or rider manipulates the hydraulic control 10 , thereby changing the volume of the air chamber 32 . This movement may increase or decrease the air pressure within the air chamber 32 . Connecting the air chamber 32 to the outside world can use equal air pressure changes caused by the movement of the baffle 28 . In addition, the air channel 18 includes a channel opening 34 facing the outside. This feature facilitates direct contact with the outside world, thereby simplifying the path of airflow between the air chamber 32 and the outside world. The hydraulic control device 10 defines a passage opening 34 between the oil sump 22 and the cover 25, as shown in the sixth figure.

空氣通道18另外包括複數個通道開口34。換言之，空氣通道18的通道開口34為該等複數個通道開口34之一者。雖然第六圖例示彼此相對的兩通道開口34，不過應了解，複數個通道開口34可包括超過兩通道開口，並且可用任何方式配置，像是例如圍繞蓋子25的周邊等距分佈。 The air channel 18 additionally includes a plurality of channel openings 34 . In other words, the channel opening 34 of the air channel 18 is one of the plurality of channel openings 34 . Although the sixth figure illustrates two channel openings 34 opposite each other, it should be understood that the plurality of channel openings 34 may include more than two channel openings and may be arranged in any manner, such as, for example, equally spaced around the perimeter of the lid 25 .

空氣通道18更包括沿著不同於該第二方向D2的一第三方向D3延伸之一第三部分18c。隨空氣通道18用以包括一第三部分18c，第二部分18b配置在第一部分18a與第三部分18c之間。在此具體實施例，空氣通道18包括複數個第二部分18b。換言之，空氣通道18的第二部分18b為該等複數個第二部分18b之一者。空氣通道18更包括一第四部分18d，其連通該等複數個第二部分18b之每一者。在此具體實施例，空氣通道18包括複數個第三部分18c。換言之，空氣通道18的第三部分18c為該等複數個第三部分18c之一者。第四部分18d連通該等複數個第三部分18c之每一者。如第六圖所示，第一、第二和第三部分18a、18b、18c都設置於蓋子25內，並且第四部分18d由蓋子25的圓周凹槽和油槽22的內表面22a所界定。在此具體實施例，該第一方向D1與該第三方向D3彼此平行。因此，該第二方向D2與該第三方向D3垂直。 The air passage 18 further includes a third portion 18c extending along a third direction D3 different from the second direction D2. With the air passage 18 configured to include a third portion 18c, the second portion 18b is disposed between the first portion 18a and the third portion 18c. In this particular embodiment, the air passage 18 includes a plurality of second portions 18b. In other words, the second portion 18b of the air channel 18 is one of the plurality of second portions 18b. The air passage 18 further includes a fourth portion 18d that communicates with each of the plurality of second portions 18b. In this particular embodiment, the air channel 18 includes a plurality of third portions 18c. In other words, the third portion 18c of the air channel 18 is one of the plurality of third portions 18c. The fourth portion 18d communicates with each of the plurality of third portions 18c. As shown in Figure 6, the first, second and third portions 18a, 18b, 18c are all disposed within the cover 25, and the fourth portion 18d is bounded by the circumferential groove of the cover 25 and the inner surface 22a of the oil groove 22. In this embodiment, the first direction D1 and the third direction D3 are parallel to each other. Therefore, the second direction D2 is perpendicular to the third direction D3.

請即參考第八圖，油槽22為長條形，如此槽開口24的寬度W小於油槽22的最大深度D。如此，槽開口24受限的大小減少接觸環境，及油槽中流體對環境中元素的潛在污染。此外，此組態進一步讓液壓槽12能夠沿著液壓控制裝置10佈置，使得液壓槽12和液壓控制裝置10可在自行車1上實現流線型輪廓。請即重新參考第八圖，油槽22具有圓形或多邊形的剖面。 Please refer to FIG. 8 , the oil groove 22 is elongated, so the width W of the groove opening 24 is smaller than the maximum depth D of the oil groove 22 . As such, the restricted size of the sump opening 24 reduces exposure to the environment and potential contamination of elements in the environment by the fluid in the sump. Furthermore, this configuration further enables the hydraulic grooves 12 to be arranged along the hydraulic control device 10 so that the hydraulic grooves 12 and hydraulic control device 10 can achieve a streamlined profile on the bicycle 1 . Please refer to FIG. 8 again, the oil groove 22 has a circular or polygonal cross-section.
