Abstract (en)
The accumulator has a pressure container (1) flow-conductively connected to a hydraulic system, and a pressure peak compensation device (2) arranged in the container, which is made of metallic material. The pressure peak compensation device is formed by a compressible pressure compensating body (3), which is loosely arranged in the container. The compensating body is formed by a closed cell foam body (4). The foam body is surrounded by a resilient sheath that is impermeable to medium to be stored. An inner side of a pressure chamber is provided with a coating (7) made of PTFE.
