Abstract
A compression spring assembly is disclosed herein. The compression spring assembly may be used in a fuel injection device and may include a compression spring having first and second adjacent turns spaced apart by a distance. The compression spring assembly may further include a damping element arranged between the first and second turns and having first and second spaced apart support regions separated by an arched third support region. The first and second support regions may be configured to exert force on a surface of the first turn, and the third support region may be configured to exert force on a surface of the second turn to at least inhibit movement of the first turn toward the second turn during operation of the spring.
