In addition, the seating surface of the valve body is adapted to be formed of a resin member, and the voltage regulator is adapted to change the setting value of the drive voltage depending on detected temperature by the temperature sensor."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Valve device and valve control device","description":"In order to suppress changes in opening level and flow rate associated with the thermal expansion of a resin member caused by a temperature change, a valve device that displaces a valve body by applyi","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10480669","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.
