Air brakes in automobiles work Pascal's principle. What about air brakes ? Collect the information about the working process of air brakes.

Explanation

1. Air brakes works on the principle of conversion of energy. Generally in trains, while it is moving it produces kinetic energy. This kinetic energy has to be reduced to make the train stop. Here air is used to reduce kinetic energy by converting it into heat energy.
2. The system of aer brakes in trains has been shown in the figure.
3. The important parts are compressor, main reservoir, driver's brake block.
Working :
1. When the driver placed the value in application position, the air pressure in the brake pipe escapes.
2. The loss of pressure is detected by the slide value in the triple value.
3. Now a connection between the auxillary reservoir and the brake cylinder has been opened and the air in the auxillary reservoir feeds through into the brake cylinder.
4. The air pressure forces the piston to move against the spring pressure and causes the brakes to be applied to the wheels.
