<p>PROBLEM TO BE SOLVED: To supply such an amount of oxygen that does not cause an oxygen shortage to a driver and an occupant at all times by providing an oxygen detector in a cabin or a helmet and comparing an output signal from the oxygen detector with an amount of oxygen which is set to control an amount of oxygen supplied from an oxygen generator. SOLUTION: An oxygen generator 1 is provided in a car, and a control valve 2 is provided on a discharge side. This control valve 2 is controlled by a controller 3 in which an output signal of an oxygen detector 4 set in the car is input. That is, when oxygen is likely to be short, an amount of oxygen in the car is detected by the oxygen detector 4 and is input into the controller 3. The amount of oxygen in the car is compared with an amount of oxygen in the car which is set in advance in the controller 3 to control the control valve 2 so that the amount of oxygen in the car is constant. Further, the control valve 2 may perform the proportional control or ON/OFF control depending on a case. Consequently, an amount of oxygen in the car is controlled to be constant at all times irrespective of the number of occupants.</p> |
