The pressing plate moves in a direction of expanding the liquid storage chamber, whereby the valve in contact with the pressing plate moves and makes a valve opening degree of the outflow port high. A range of motion of the valve when making the valve opening degree of the outflow port high is limited by a member other than the pressing plate."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Pressure control unit and liquid discharge device including pressure control unit","description":"A pressure control unit includes a liquid storage chamber, an inflow port that allows the liquid to flow therein, and an outflow port that allows the liquid to flow out thereof, the pressure control u","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11520359","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.
