Piston retention system for a fastener driving tool |
摘要 |
In a fastener driving tool, a retention system for a piston comprises a buffer and a set of bearings in a cage, the bearings being abutted against the buffer. The buffer provides a force urging the bearing radially inwardly toward the piston so that the bearings retain the piston in a predetermined position when the piston is not being actuated.
