Fuel tanks used in vehicles are equipped with a breather at the upper end to remove vaporized fuel and prevent the pressure inside the fuel tank from increasing. Generally, as shown in Fig. 3, a check valve B attached to the upper end of the fuel tank A is connected to a separation chamber C formed by welding a combination of several dish-shaped steel plates press-formed to the lower side. In the separation chamber C, liquid fuel and vaporized fuel are separated. As described above, the separation chamber C formed of a plate-shaped pressed steel plate requires a large number of press molds, takes a lot of processing time, and has the disadvantage of increasing manufacturing costs.
この考案は、かかる点に鑑み、左右二片の鋼板
で分離室を形成し、プレス型を少くすると共に、
加工の手間も少くして、製造コストを低減できる
燃料タンクのブリーザを、得ることを目的とす
る。
In view of these points, this idea forms a separation chamber with two pieces of left and right steel plates, reduces the number of press dies, and
The purpose of the present invention is to obtain a breather for a fuel tank that requires less processing time and can reduce manufacturing costs.
以下、本考案を第１図及び第２図に示す実施例
について説明する。
Hereinafter, the present invention will be described with reference to an embodiment shown in FIGS. 1 and 2.
膨み部１の下側の側方に抜ける通路２を設けて
分離室３に接続し、分離室３の下部に小さい開口
４を設け、上端にガス抜き孔５を設けるように、
左右に分けた鋼板でプレス成形し、これを最中状
に合せて、シーム溶接等によつて溶着する。そし
て、膨み部１を、燃料タンク６の上端に取付ける
チエツクバルブ７の下端に嵌め合わせて溶着す
る。 A passage 2 passing through the lower side of the swollen portion 1 is provided to connect it to a separation chamber 3, a small opening 4 is provided at the bottom of the separation chamber 3, and a gas vent hole 5 is provided at the upper end.
Press-form the left and right steel plates, align them in the middle, and weld them together by seam welding or the like. Then, the bulge 1 is fitted and welded to the lower end of the check valve 7 attached to the upper end of the fuel tank 6.
しかして、分離室３及び膨み部１は、通路２、
開口４、ガス抜き孔５を含めて、左右二片の鋼板
で形成するので、プレス型が少くて済み、加工の
手間も少くて、製造コストを低減できる。そし
て、通路２は、側方に曲げられて分離室３を横向
きに接続するので、下方に突出するのも少くでき
る。 Thus, the separation chamber 3 and the bulge 1 are connected to the passage 2,
Since the opening 4 and the gas vent hole 5 are formed from two pieces of steel plate, left and right, the number of press dies is small, the processing effort is also small, and the manufacturing cost can be reduced. Since the passage 2 is bent laterally to connect the separation chambers 3 laterally, the amount of downward protrusion can be reduced.
以上説明したように、この考案は、プレス形成

その膨み部の下端に側方に抜ける通路を介して接
続された分離室を形成するとともに、上記分離室
の下部に小さい開口を設け、さらに分離室の上端
にガス抜き孔を設けたので、分離室と膨み部を通
路、開口、ガス抜き孔を含めて、左右二枚の鋼板
で形成でき、プレス型を少くし、加工工数も少く
でき、製造コストを低減することができる。
As explained above, this invention has a bulge connected to the check valve by welding press-formed left and right steel plates in the middle,
A separation chamber was formed at the lower end of the swollen portion and connected via a passage extending laterally, a small opening was provided at the bottom of the separation chamber, and a gas vent hole was provided at the upper end of the separation chamber. The separation chamber and the bulge, including the passages, openings, and gas vent holes, can be formed from two left and right steel plates, reducing the number of press dies and processing steps, and reducing manufacturing costs.
