Respirator Flow Control Apparatus And Method |
| 摘要 |
A respirator has a shell that defines a breathable air zone for a user wearing the respirator. An air flow control system for the respirator has an air delivery conduit within the shell of the respirator, a valve member moveable relative to the air delivery conduit and within the shell to vary the amount of air flow through the air delivery conduit, and a valve actuator outside of the shell of the respirator. The valve actuator is manipulatable by a user of the respirator while wearing the respirator to control movement of the valve member. |

1. An air flow control system for a respirator, the control system comprising:
a shell defining a breathable air zone for a user; an air delivery conduit within the shell of the respirator and having an air flow inlet end extending through an air inlet opening of the shell, the conduit being separable from the shell; a valve member moveable relative to the air delivery conduit and within the shell to vary the amount of air flow through the air delivery conduit; and a valve actuator outside of the shell of the respirator that is manipulatable by a user of the respirator while wearing the respirator to control movement of the valve member. |
