🔍 Key Concepts

• Study how moving handle E affects parts F, G, and valve C in the illustration. • Think about the role of chamber I and the small passage at H in building or releasing pressure above valve C. • Consider whether the valve closes because of pressure building above C or because of a vacuum in chamber III below C.

💭 Think About

• When the handle is first operated, which part must move first for flow to start: A, C, or something in chamber III? • After flow is underway, does the system rely more on a gradual pressure change through H or on instant suction in chamber III to push C back onto its seat? • What does releasing handle E actually do to the linkage at G—does it actively pull C shut, or simply stop holding it open so another force can close it?

✅ Before You Answer

• Verify which way valve C moves to open and close, using the shading and shapes around its seat. • Check whether part A appears to vent or seal chamber I and how that would affect pressure on top of C once water is flowing. • Confirm whether chamber III has any direct connection to atmosphere or other path that would realistically create a strong vacuum, or if pressure changes there are secondary to what happens in chamber I.
