Understanding Piston and Valves

What is the role of the trigger in the process?

• To move the inlet valve

• To make the piston move in

• To open the outlet valve

• To decrease water pressure

How does the trigger affect the piston?

• It increases the water pressure

• It makes the piston move out

• It causes the piston to move in

• It closes the outlet valve

What happens when the piston moves in?

• Water pressure decreases

• The outlet valve opens

• The inlet valve opens

• Air enters the chamber

What happens when the piston moves out?

• Water flows into the chamber

• Water pressure increases

• The outlet valve opens

• The inlet valve closes

How does the piston influence water pressure?

• It keeps the pressure constant

• It increases pressure when it moves out

• It increases pressure when it moves in and decreases pressure when it moves out

• It decreases pressure when it moves in

What is the job of the outlet valve when the piston moves in?

• To stop air from entering the chamber

• To allow water to flow out of the chamber

• To let water flow into the chamber

• To close during high pressure

Why does the outlet valve open when there is high water pressure?

• To prevent air from entering the chamber

• To allow water to flow out of the chamber

• To let water flow into the bottle

• To stop water backflow

What happens to the outlet valve when the piston moves out?

• It opens to let water flow in

• It closes to prevent air from entering

• It stays open due to low pressure

• It lets water flow back into the bottle

What does the inlet valve do when the piston moves in?

• It opens to allow water to flow into the chamber

• It closes to prevent water backflow

• It closes to stop air from entering the chamber

• It opens to release water out of the chamber

Why does the inlet valve close during high pressure?

• To let water flow back into the bottle

• To stop air from entering the chamber

• To prevent water from flowing back into the bottle

• To open the outlet valve
