The reciprocating piston has an inner channel to transport a cleaning fluid through the reciprocating piston to a spray nozzle. A miniaturized, easily and inexpensively producible cleaning apparatus which makes possible exact and precise orientation of the cleaning jet, quick operational readiness, reduced tendency for follow-up flow of the cleaning fluid, and improved adaptability to different installation positions, is also disclosed. In an embodiment at least the cleaning apparatus has at least one guide to prevent rotation of the reciprocating piston about the actuation axis during its entire stroke, the at least one guide means arranged at least regionally in the inner channel."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Cleaning apparatus having a piston","description":"A cleaning apparatus, optimized for cleaning optical and optoelectronic sensor devices in motor vehicles, comprising a housing, and a reciprocating piston movable in a pressure-controlled manner in th","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11938906","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.
