【発明の詳細な説明】 本発明は別の封止蓋を使用することなく圧力容器に設け
たガス導入通路を封止するようにした圧力容器に関する
ものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a pressure vessel in which a gas introduction passage provided in the pressure vessel is sealed without using a separate sealing lid.

これにより前記ガス導入通路を閉じるようにしていた。In order to enclose compressed gas in a conventional pressure vessel, such as a gas spring or a gas-filled shock absorber, a gas introduction passage closed to the outside is provided in a part of the cylinder that forms the main body of the vessel, and a gas introduction passage is provided inside from the gas introduction passage. After filling the compressed gas, a plug is fitted into the gas introduction passage and settled in the pressure vessel,
This closes the gas introduction passage.

するものである。As mentioned above, conventionally the gas introduction passage is formed by drilling a hole in a part of the pressure vessel, and the gas introduction passage is sealed with a plug, so it is necessary to deburr the gas introduction passage when machining it. However, the problem remains that the work efficiency is poor and the cost is high because a separate plug is required. Furthermore, since the plug and the pressure vessel are completely separate members, there remains a problem in quality control. The present invention solves the above problems and is characterized in that a part of the pressure vessel is used as a plug for closing the gas introduction passage.

場合について説明する。Embodiments of the present invention will be described below with reference to the drawings. Figure 1,
As shown in FIG. 2, a cap 2 is a part of the pressure vessel 1.
Two parallel cuts 2a and 2b are provided in a part of the gas introduction passage 3, and the space between the cuts 2a and 2b is raised outward in an arch shape to form a raised portion 2c, thereby forming a gas introduction passage 3. . Here, when the raised portion 2c is pressed against the cut portions 2a and 2b of the cap 2, the raised portion 2c has been stretched out during the processing process, so the raised portion 2c is pressed against both the cut portions 2a and 2b. The outer surface 2c of the cap 2 and the inner surface x' of the raised portion 2 overlap to form a contact portion for welding without aligning closely. A case in which compressed gas is sealed in the pressure vessel having the above configuration will be described.

により出来た空間をガス導入通路３としたものである。First, the gas introduction passage 3 is made to face into the gas atmosphere chamber 4, and the chamber 4 and the outside are airtightly isolated by the sealing member 5.
Then, the valve 6 is opened to supply compressed gas from the fluid source 7 into the gas atmosphere chamber 4, and the compressed gas is introduced into the pressure vessel 1 through the gas introduction passage 3. After a predetermined amount of compressed gas is introduced into the pressure vessel 1, the inner surface 2c of the raised portion 2c is pressurized and deformed using the electrode 8 until it comes into contact with the outer surface 2 of the cap 2, welding them together, and forming the raised portion. The gas introduction passage 3 is closed at the portion 2c and compressed gas is sealed inside. Figure 3 "Figure 4 shows another embodiment of the present invention, in which the pressure vessel 1
In this embodiment, two parallel cut parts 2a and 2b are provided in a part of the cap 2, and the space between them is raised to form the gas introduction passage 3. However, in this embodiment, three sides are cut in a part of the cap 2. A quadrilateral raised portion 2c is formed by bending from the remaining side, and a space created by bending the raised portion 2c outward is defined as a gas introduction passage 3.

c is actually formed at the same time as the cap 2 is manufactured by press molding, so no separate process is required.

る。As described above, the present invention provides a part of the pressure vessel with a cut.
A gas introduction passage was formed by forming a raised part that protruded outward from this cut part, and the gas introduction passage was closed by returning the raised part to its original position.
Not only is there no need to provide a hole for inserting the plug, but there is also no need for deburring to insert the plug.
