Flexible partition member for hydraulic accumulator, including ethylene-vinyl alcohol copolymer gas-barrier layer and polyamide resin elastic layer |
摘要 |
A flexible partition member for a hydraulic accumulator, which divides an interior of a shell of the accumulator into two sections that provide a gas chamber and a liquid chamber, respectively. The flexible partition member includes an integrally layered composite portion which includes at least one gas-barrier layer and at least one elastic layer, each gas-barrier layer containing a copolymer of ethylene and vinyl alcohol, and each elastic layer containing as a major component thereof a polyamide resin selected from the group consisting of nylon 6, nylon 66, nylon 6-10 and nylon 6-12. The integrally layered composite portion includes two adjacent layers which include a gas-barrier layer and an elastic layer.
