The storage volume is sealed so that an increase in an internal gas pressure occurs in the storage volume when liquid is introduced. The device further comprises a detection unit for detecting the supplied volume of the second liquid into the storage volume and the internal gas pressure in the storage volume, and a control unit controls the supply of the second liquid based on the detected supplied volume of the second liquid and the internal gas pressure so that a predetermined mixing ratio of the first and second liquid is achieved in the storage volume."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Liquid ejection device for a vehicle washing facility, and method for operating same","description":"A liquid ejection device for a vehicle washing facility comprises a storage volume, a first supply line coupled upstream to the storage volume for supplying a first liquid, a supply unit coupled upstr","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11994882","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.
