GUIDE FOR A MOVABLE MEMBER

摘要

A guide for supporting sliding movement of a movable member includes a guide body (12) having an outer surface (13), a first portion (14) defining a first end of the guide and a second portion defining a second end (22) of the guide body. A void (24) is provided between the first and second ends and is defined by an inner surface of the guide body. A plurality of cooling projections (26) project from the outer surface of the first portion, and a flange (18) 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 (46).
