A monitoring device (46) is provided, which, in the event of a fault impairing the sealing effect of the separating element (16), provides an optically discernible indication and has an inspection window (54), through which an indicator can be observed. The monitoring device is connected to the gas chamber (12) and changes optical properties discernibly when wetted with the fluid. The indicator changing its optical properties is accommodated in a capsule (48) with a capsule wall (50) permeable to the passage of the fluid and arranged between the inspection window (54) and the separating element (16) in the accumulator housing (10)."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Pressure accumulator having a monitoring device","description":"A pressure accumulator having an accumulator housing (10) in which a movable separating element (16) separates a gas chamber (12) filled with a working gas from a fluid chamber (14) in a fluid-sealed ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11268541","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
