Often in ac circuit by air damping model time relay, it is to use the principle of air through orifices throttling to obtain delay action.

在交流电路中常采用空气阻尼型时间继电器，它是利用空气通过小孔节流的原理来获得延时动作的。

Early in the circuit often USES air damping model time relay, it is to use the principle of air through orifices throttling to obtain delay action.

早期在交流电路中常采用空气阻尼型时间继电器，它是利用空气通过小孔节流的原理来获得延时动作的。

If uneven pressure should cause the regulator to pulsate, its action can be stabilized by throttling the valve.

如果不稳定的压力导致调节阀波动，则这种波动通过对阀门节流将稳定下来。
