Abstract
Abstract A motion transmitting remote control assembly of the type for transmitting motion in a curved path by a flexible core element (12) in a conduit (18) and a method of making same. An end fitting (20) is disposed about the conduit (18) by a cylindrical section which includes abutments (24). A vibration dampener (16) includes a cylindrical tube disposed about the end fitting (20) with grooves (28) aligned with the abutments (24) and tabs (30) extending radially outward from the vibration dampener (16). A support (14) includes a cylindrical wall (32) disposed about and coextensive with the vibration dampener (16) with openings (34) aligned with the tabs (30) of the vibration dampener (16). The vibration dampening means (16) is in axial mechanical interlocking engagement with the end fitting (20) and support (14) for maintaining the vibration dampener (16) free of radial compressive forces.
