This style of ballcock uses a base fill water release tube and comes with a pivoted switch system over the ballcock.

The cylinder rises and falls with the water level in the tank. Some fill valves are adjustable to fit different tank sizes. Plunger or piston style fill valves are perhaps the very first types ever.
