Question 1 of 27070

A device incorporating a variable orifice placed in series with a check valve in a hydraulic system, is used to __________.

🔍 Key Concepts

• Check valve function – which direction does it allow flow? • Variable orifice / throttle valve – what does changing the opening size do to flow? • How series connection (one after the other) affects overall flow direction and restriction

💭 Think About

• First, picture what a check valve alone does. Can fluid pass freely in both directions, or only one? • Next, imagine adding a variable orifice in series with that check valve. In the direction fluid is allowed to pass, will the flow be free or controlled (throttled)? • In the blocked direction of the check valve, does adding an orifice in series change the fact that flow is blocked?

✅ Before You Answer

• Be clear about direction of free flow vs. blocked flow in a check valve. • Decide whether a variable orifice affects flow in one direction, both directions, or only when flow is allowed. • Eliminate any option that describes behavior opposite to what a check valve does by design.
