BREATHING SENSING DEVICE

Patentradars sammanfattning

The invention provides a magnetic valve architecture integrated into a breathing sensing device for diving safety equipment. A flexible diaphragm carries a valve actuating magnet on its exterior face; inside the sealed valve chamber, a valve seal magnet is mounted on a biased pivoting arm connected to a valve seal. When differential pressure deflects the diaphragm, the decreasing gap between the two magnets generates a repulsive force sufficient to overcome the bias and open the valve port without any physical contact through the chamber wall. This contactless actuation eliminates the friction and hysteresis inherent in conventional piston-and-lip-seal arrangements, enabling a diaphragm diameter reduction of 70% or more and yielding a significantly more compact, reliable, and scalable pressure-sensing safety actuator.
