🔍 Key Concepts

• Spring-loaded valve function when connected directly to a cylinder’s combustion space • Meaning of “blow-off pressure” and how it relates to safety devices • Difference between a relief/safety device and an indicator or fuel injector

💭 Think About

• Look at the labeled parts: spring, valve body, valve seat, distance ring. What type of device uses a spring and an adjustable ring to open at a preset pressure? • The note says changing the distance ring thickness changes the blow-off pressure. In engine practice, what does “blow-off” usually describe? • Which option best matches a device that opens automatically at a certain pressure rather than something that is manually used for testing or starting?

✅ Before You Answer

• Does the device show any connection point for gauges or instruments, or only a valve body and spring? • Does the illustration show any fuel passages or spray holes like a fuel injector would have? • Remember that a device with an adjustable opening pressure is typically used to protect or signal dangerous overpressure—see which choice reflects that role.
