METAL BELLOWS-TYPE ACCUMULATOR
Document Type and Number:
WIPO Patent Application WO/2017/126354
Kind Code:
A1
Abstract:
The amplitude of an abdomen section of a metal bellows due to vibrations is suppressed to prevent breakage of the metal bellows. A metal bellows-type accumulator 1 comprising a metal bellows 2 that divides the space in a housing 5 into a gas chamber 8 that seals a gas and a liquid chamber 9 leading to an oil port 3, is characterized in that a bellows cap 7, a seal member 14, and a seal holder 13 are provided more to the gas chamber 8 side than a free end 2b of the metal bellows 2 so that a center of gravity G of a moveable member that moves together with the expansion and contraction of the metal bellows 2 approaches the free end 2b of the metal bellows 2 as much as possible, and in that the bellows cap 7 is provided with a weighting means.
