ABSTRACT:
A valve stem sealing device used for preventing oil from entering a combustion chamber through a gap formed between a valve guide and a valve stem is disclosed. The valve stem sealing device comprises an annular oil seal surrounding a valve stem and an annular support member fixed to the top of the valve guide so as to hold the oil seal in its place, wherein the support member has an inwardly opening annular recess and rotatably receives the oil seal in the recess, with a bearing being positioned between said oil seal and the side wall of the support member. In addition, a rubber member is tightly interposed between the support member and the valve guide so as to absorb the vibrations caused by a valve operation. Also, a support cap covers the outside wall of the oil seal so that the outside wall of the support cap is brought into contact with the bearing.
