The spring disc includes: a secondary-pressure receiving surface being a portion moving along with a movement of the poppet valve, the secondary-pressure receiving surface configured to receive secondary pressure introduced to the secondary port; and a pilot-pressure receiving surface configured to receive pilot pressure serving as a reference pressure. The spring disc deforms elastically in accordance with pressure difference between the secondary pressure and the pilot pressure to cause the poppet valve to move in the axial direction."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Control valve","description":"A control valve includes a poppet valve moving in an axial direction relative to a seat hole so as to change a flow-path cross-sectional area of the seat hole and a spring disc biasing the poppet valv","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9684315","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.
