2. Description of the Related Art Conventionally, there has been a problem that assembling a metering valve is difficult due to its complicated structure.
Due to the complicated structure, the user is confused by the fact that the user is liable to break down during use. Therefore, at the time of pressure filling, a passage for filling must be reliably opened. Therefore, in order to make the passage for filling open, a smaller hole must be formed in a member that is originally small in the stage of manufacturing the metering valve, and the technique and the work are not easy.

[0003]

The structure of the valve housing of the pressure-fillable large quantity metering valve according to the present invention is a complicated structure only by fitting the large part of the upper part of the metering valve for the metering chamber into the middle cylinder of the mountain cap. The first object is to form a constant-quantity valve. The structure of the valve housing of the pressure-fillable mass metering valve of the present invention is such that the diameter of the mountain cap is the same as the size of the sealing member of the mountain cap, but is positioned sufficiently smaller than that, making the insertion operation extremely easy. Second to get
Subject.
