System Parts第 2 / 60 题
What does the air compressor governor control?
a.The temperature of the compressed air
b.The speed of the vehicle at highway speeds
c.When the compressor pumps air into the tanks
d.The pressure applied to the brake drums
解析
The governor controls when the compressor pumps air into the storage tanks. When tank pressure reaches the cutout level (around 125 psi), the governor stops the compressor from pumping. When pressure falls to the cut-in level (around 100 psi), it allows the compressor to start pumping again.
