A solenoid operated pilot valve member, disposed in the pilot fluid passage can have a metering orifice operable in combination with the metering land for selectively connecting the valve control port with a pressurized fluid supply port and a return exhaust port in response to activation of a solenoid. A flow amplifying spool valve member, in fluid communication with the valve control port of the pilot valve member at one end, can selectively connect a load control port with the pressurized fluid supply port and the return exhaust port in response to pilot valve member operation."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Two-stage variable force solenoid","description":"A two-stage, variable force, solenoid control valve for regulating fluid pressure can include a valve body having a pilot fluid passage, including a metering land, in fluid communication with a flow a","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9599245","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.
