Title:
金属ベローズ型アキュムレータ
Document Type and Number:
Japanese Patent JP6708639
Kind Code:
B2
Abstract:
The purpose of the present invention is to provide a metal bellows-type accumulator in which reduced durability due to a metal bellows (2) vibrating in the radial direction and contacting the inner circumferential surface of an outer shell (1) does not occur. To achieve said purpose, the bellows-type accumulator is provided with: an outer shell (1), on one end of which a pressure-introducing passage (C) is opened; and a metal bellows (2) which comprises ridges (211) facing radially outward and troughs (212) facing inward formed in a repeating pattern, is capable of expanding and contracting in the axial direction, and which partitions the inner chamber of the outer shell (1) into a pressure introduction chamber (A) that is in communication with the pressure-introducing passage (C) and a gas chamber (B) in which a cushioning gas is sealed. The area in the metal bellows (2) where the amplitude of radial direction vibration is maximal is provided with a cylindrical section (213) that has a larger diameter than the maximum diameter of the various ridges (211) and is capable of contacting the inner circumferential surface of the outer shell (1) with a prescribed width in the axial direction.
