ABSTRACT:
An impact plate for use in a component having parts that move at high velocity, such as a piston or valve, controls energy transfer during impact of the moving part. The impact plate has a recessed inner portion that acts as an impact surface and an outer support surface to hold the impact plate within a housing of the component. The impact surface has a selected, controlled spring rate so that it can deflect and absorb impact forces when the moving part contacts it.
