Abstract
A guide for supporting sliding movement of a movable member includes a guide body having an outer surface, a first portion defining a first end of the guide body, and a second portion defining a second end of the guide body. A void is provided between the first and second ends and is defined by an inner surface of the guide body. A plurality of cooling projections project from the outer surface of the first portion, and a flange for stabilizing the guide projects radially from the guide body and defines a boundary between the guide's first and second portions. The guide may be adapted as, for example, a valve guide for use in an internal combustion engine for guiding the reciprocating sliding movement of a valve stem.
