Question: 1 / 125

If the air system leaks, what would hold the air in the tanks together?

The governor

The one-way check valve

The one-way check valve plays a crucial role in maintaining air pressure within the tanks in an air brake system. This valve allows air to flow in one direction, ensuring that compressed air remains in the storage tanks and does not escape back through the system when there is a leak. By preventing backflow, the one-way check valve helps to retain pressure and ensure that there is adequate air supply for the operation of the braking system.

In contrast, components like the governor monitor and regulate air pressure but do not specifically prevent air loss. The emergency relay valve and the tractor protection valve serve different purposes within the air brake system, primarily focusing on safety and ensuring proper function during emergencies, rather than holding air in the tanks against the backdrop of a leak. Thus, the one-way check valve is essential for maintaining air pressure and integrity of the air supply in the event of a leak.
