METHOD OF EXTENDING ENGINE SERVICE LIFE AND ANGULAR DISPLACEMENT-LIMITING CLIP FOR SAME

摘要

A clip (92) includes a one-piece metal body (93) having a holder (94) and an attached hanger (96). The clip (92) is configured to couple with a valve lifter (42) to form a lifter assembly (30) for varying the position of a valve (36) in an internal combustion engine (10). The holder (94) may be C-shaped, and the hanger (96) may be U-shaped. The one-piece metal body (93) further includes an anti-scuffing outer profile, and a first and a second fillet (114) transitioning from the holder (94) to the hanger (96), for diffusing stresses induced in the clip (92) at an angular displacement-limiting stop position defined by contact between the hanger (96) and a wall portion (19) of a cylinder block (14). Related methodology is disclosed.
