Abstract

A rotatable rigid material valve operator is provided having a threaded shank threadedly engaged within a threaded blind bore formed in a valve member constructed of thermo plastic elastomer having an 80-90 'SHORE' scale durometer hardness and snugly slidingly disposed within a valve body bore against rotation relative thereto, the threaded shank being rotatable relative to the valve body against axial displacement relative thereto such that rotation of the threaded shank translates into axial shifting of the valve member within the valve body bore. The compressive resiliency and thickness of the walls of the valve member defining the blind bore are such that the threaded connection between the shank and the threaded blind bore may 'slip' independent of 'stripping' of the threaded connection between the threaded shank and the valve body threaded blind bore when the valve member is in a limit of axial shifting thereof and the threaded shank is inadvertently further rotated, thereby retaining the threaded connection between the threaded shank and the valve member threaded blind bore for subsequent axial adjustment of the valve member by its threaded connection with the threaded shank.
