The hydraulic starting motor is operated by...

🔍 Key Concepts

• Understand what provides pressurized flow in a hydraulic system versus what only stores or contains fluid • Know the difference between a source of pressure (active) and a reservoir/accumulator (passive storage) • Relate how a starting motor needs a steady, controlled supply of high‑pressure fluid to operate

💭 Think About

• Ask yourself: which component in the list is normally responsible for actually creating and maintaining pressure/flow in operation, not just holding fluid? • Which item would be in continuous or regular motion when the system is running, supplying hydraulic power to various consumers like a starting motor? • Which options are mainly for storage or backup rather than primary, ongoing pressure supply?

✅ Before You Answer

• Identify which choice is the primary source of hydraulic pressure and flow during normal operation • Separate components that only store fluid or energy from those that actively move fluid • Confirm that your selected component could realistically drive multiple hydraulic loads, including a starting motor, during normal use
