Q

Restrictions occurring in the small orifices of pneumatic control system components can be caused by __________.

🔍 Key Concepts

• pneumatic control systems and how air quality affects small passages/orifices • the difference between liquid contamination, lack of lubrication, and pressure variations • how water vapor in compressed air behaves when temperature or pressure changes

💭 Think About

• Think about what happens when compressed air cools down after compression—what can form inside the lines and small passages? • Which option is most likely to create a physical blockage in a tiny orifice rather than just change how smoothly parts move? • Consider which condition would actually change flow area through an orifice versus only affecting wear or speed of components.

✅ Before You Answer

• Identify which choices relate to contamination that can solidify or collect inside a small opening. • Separate issues that affect lubrication and wear from those that affect clogging/blockage. • Ask yourself which condition can produce ice or sludge in small passages under certain operating conditions.
