Abstract
A cartridge for pressurized fluid. The cartridge includes a body having a cylindrical portion and a bottom having a concavity oriented toward the inside of the body. The connection between the bottom and the body is made by an annular seam. The particular structure of the connection zone provides a reduction in the diameter of the body for connection to a bottom of lesser diameter without creating zones of concentration of stresses. Another arrangement of the cartridge provides for the bottom to have a cylindrical portion that bears against the cylindrical end portion of the body, which makes it possible to create a rigid zone.
Claims9
A cartridge for pressurized fluid comprising:
- a body having a cylindrical portion of diameter D lying between 75 millimeters and 110 millimeters surmounted by a dome at one of its ends and a circular opening at its second end, and
- a bottom of diameter d less than the diameter D closing the opening of the body, the bottom having a concavity oriented toward the inside of the body, the connection between the bottom and the body being made by an annular seam,
- characterized in that the body has, in its portion adjacent to the opening, a connection zone A comprising:
- a cylindrical end portion of a height h of diameter equal to the diameter of the bottom,
- a frustoconical portion connecting the cylindrical end portion to the cylindrical body, the frustoconical portion forming an angle α with the cylindrical end portion, α lying between 10 and 30°, and the height h of the cylindrical end portion lying between 3 and 10 millimeters.
