What is claimed is: 1. A pressure vessel assembly for a pressurized fluid system, said pressure vessel assembly comprising: a hollow outer casing defining an interior cavity within said outer casing; at least one fluid-pressure accumulator disposed within said interior cavity in said outer casing; and at least one isolation device disposed between said at least one fluid-pressure accumulator and said outer casing, said at least one isolation device includes an isolator ring made of a substantially elastomeric material; said at least one fluid-pressure accumulator including an outer pressure shell and a separating member movable in said outer pressure shell; said outer pressure shell defining an enclosed fluid chamber between an inner peripheral surface of said outer pressure shell and said separating member; said enclosed fluid chamber being provided for containing a working fluid under pressure therein; said at least one isolation device further including an isolator ring support member supporting said isolator ring and a spring member disposed between said at least one closure member and said isolator ring support member for biasing said isolator ring toward said at least one fluid-pressure accumulator. 2. The pressure vessel assembly as defined in claim 1, wherein said isolator ring is made of a substantially elastomeric material. 3. The pressure vessel assembly as defined in claim 1, wherein said isolator ring support member has an annular support flange receiving said isolator ring and a substantially cylindrical guided neck slidably extending through an opening in said outer casing in the direction away from said at least one fluid-pressure accumulator. 4. The pressure vessel assembly as defined in claim 3, wherein said support flange of said isolator ring support member receives said isolator ring in a groove formed on one side thereof facing said at least one fluid-pressure accumulator, and wherein said spring member engages the other side of said support flange facing said outer casing. 5. A pressure vessel assembly for a pressurized fluid system, said pressure vessel assembly comprising: a hollow outer casing defining an interior cavity within said outer easing; at least one fluid-pressure accumulator disposed within said interior cavity in said outer casing; and at least one isolation device disposed between said at least one fluid-pressure accumulator and said outer casing; said at least one fluid-pressure accumulator including an outer pressure shell and a separating member movable in said outer pressure shell; said outer pressure shell defining an enclosed fluid chamber between an inner peripheral surface of said outer pressure shell and said separating member; said enclosed fluid chamber being provided for containing a working fluid under pressure therein; said outer casing including a hollow sidewall section and two closure members provided at opposite ends of said sidewall section of said outer casing; and said at least one isolation device including two isolation devices each disposed at one of opposite ends of said at least one fluid-pressure accumulator between said at least one fluid-pressure accumulator and one of said closure members of said outer casing. 6. The pressure vessel assembly as defined in claim 5, wherein one of said isolation devices includes an isolator ring. 7. The pressure vessel assembly as defined in claim 6, wherein said isolator ring is made of a substantially elastomeric material. 8. The pressure vessel assembly as defined in claim 7, wherein the other one of said isolation devices includes an isolator ring, an isolator ring support member supporting said isolator ring and a spring member disposed between said adjacent one of said endplate members and said isolator ring support member for biasing said isolator ring toward said at least one fluid-pressure accumulator. 9. The pressure vessel assembly as defined in claim 5, wherein each of said isolation devices includes an isolator ring. 10. The pressure vessel assembly as defined in claim 5, wherein each of said isolation devices includes an isolator ring, an isolator ring support member supporting said isolator ring and a spring member disposed between said adjacent one of said endplate members and said isolator ring support member for biasing said isolator ring toward said at least one fluid-pressure accumulator.
