A spring guard can be used to enclose a die
spring. In operation, this example shows that a die spring can be fully enclosed by the
guard and end-plate. This can improve safety because pinch-points can be eliminated.
Reliability can be improved because the die spring can be protected from foreign
materials. The cage can also provide guidance and support to decrease die spring buckling
during compression. Since the die springs diameter can expand during compression, it
may be necessary to select a larger spring guard. |
