The patent filed by Robert Bosch GmbH, dated June 20, 2024, details an advanced gas injector engineered explicitly for the injection of gaseous mediums, including hydrogen.
The notable inventors behind this technology focus on enhancing the precision and reliability of gas injection processes. The patent identifies a key component, an actuatable closure element, central to the injector’s operation.
Features and Improvements
This invention’s heart is the dynamic interplay between the valve needle and its surrounding components. The closure element, integrated as a part of the valve needle, plays a critical role by opening and closing a through-opening in the valve body. Including at least one guide element ensures the needle travels smoothly along its axial path. A standout innovation within this system is the particle deflector upstream of the guide element. This design effectively shields the guide surface from particulate contamination, thereby ensuring optimal performance and longevity of the gas injector.
Potential Applications
This sophisticated gas injector has wide-ranging applications in industries dedicated to hydrogen utilization. Primary among these is its potential in automotive and industrial hydrogen fuel systems, where precise and dependable hydrogen injection is critical for efficient combustion and operation. It could also find applications in hydrogen fuel cell technologies, where maintaining purity and controlling flow are paramount for energy generation.
Technical Specifications and Processes
Key technical aspects of this injector include:
– An actuatable closure element part of a valve needle.
– A valve needle equipped with at least one guide element for axial movement.
– A particle deflector positioned upstream of the guide element keeps particles away from the all-around guide surface.
– A sealing seat and a through-opening within a valve body for precise control over the gas flow.
These specifications underline a robust design to deliver high performance in challenging operational environments.
Key Takeaways
This patent from Robert Bosch GmbH highlights significant innovations in the field of hydrogen injection technology:
– A particle deflector will be introduced to protect key components from particulate contamination.
– Enhanced reliability and longevity of the hydrogen gas injector.
– Wide-ranging applications in the hydrogen energy sector, particularly in automotive and industrial contexts.
