When does the demand valve of the diluter demand oxygen regulator operate?

The demand valve of the diluter demand oxygen regulator operates specifically when the user inhales. This mechanism is designed to provide oxygen only during inspiration, ensuring that the user receives oxygen in response to their breathing efforts.

The diluter demand regulator allows for a controlled flow of oxygen mixed with cabin air, which is particularly important at higher altitudes where the oxygen concentration in the atmosphere decreases. By activating during inhalation, this demand valve operates efficiently, delivering oxygen only when needed and thereby conserving oxygen supply.

Understanding the function of the demand valve emphasizes the importance of breathing patterns in regulating the oxygen provided to the user, which is an essential factor in maintaining safety and comfort at high altitudes.
