A spring keeper for maintaining a high energy spring comprising:
- an outer barrel;
- an inner barrel slideable within the outer barrel;
- a first centerer fitted inside the inner barrel, said first centerer comprising a first base and a first projection projecting axially from the first base for being received within a first end portion of a spring;
- a second centerer fitted inside the outer barrel, said second centerer comprising a second base and a second projection projecting axially from the second base for being received within a second end portion of the spring;
- a layer of a wear resistant material covering at least a portion of the outer surface of the inner barrel that is received within the outer barrel;
- and
- another layer of wear resistant material covering an inner surface of the inner barrel, wherein said layer and another layer of wear resistant material extend beyond the inner barrel and are connected to each other at a location beyond the inner barrel.
A spring assembly comprising:
- a high energy spring;
- and
- a spring keeper, the spring keeper comprising,
- an outer barrel,
- an inner barrel slideable within the outer barrel,
- a first centerer fitted inside the inner barrel, said first centerer comprising a first base and a first projection projecting axially from the first base and received within a first end portion of the spring,
- a second centerer fitted inside the outer barrel, said second centerer comprising a second base and a second projection projecting axially from the second base and received within a second end portion of the spring,
- a layer of a wear resistant material covering at least a portion of the outer surface of the inner barrel that is received within the outer barrel, and
- another layer of wear resistant material covering an inner surface of the inner barrel, wherein said layer and another layer of wear resistant material extend beyond the inner barrel and are connected to each other at a location beyond the inner barrel.
