This apparatus is a specialized tool utilized to accurately measure the force exerted by a valve spring at specific compression heights. An example of its application is in engine rebuilding, where it verifies that the springs meet the manufacturer’s specifications, ensuring proper valve closure and preventing valve float at high engine speeds.
Precise measurement of spring force is critical for optimizing engine performance and durability. Deviations from specified pressure can lead to reduced engine power, increased wear on valve train components, and potential engine damage. Historically, less sophisticated methods were used, often relying on estimations and approximations, leading to inconsistencies in engine builds. The emergence of accurate testing devices has significantly improved engine reliability and performance tuning.
