22 / 30

The compressor's intake system draws air from either its own air filter or...

The reservoir

From a motorized fan

From the engine's intake system

From the outside atmosphere

23 / 30

What is referred to as a diaphragm?

A heavy rubber partition in the brake chamber that activates the brakes when air is forced against it

A rubber seal that stops air from penetrating it

A small port

None of these

24 / 30

What is referred to as compressed air?

When air is pushed into a smaller space
