Abstract

PURPOSE: To perform shift of the axial direction of a poppet valve smoothly by forming at least one pair of oil grooves opposite to each other in an oiling part of the poppet valve.
CONSTITUTION: A seal part 2 of a poppet valve 1 consists of a column part 5 with two faces bevelled and a truncated cone part 6 brought in contact with a valve seat subsequently to connection of a larger diameter side to the column part. The profile of an oiling part 4, with its opposed two pairs of oil grooves 7 concavated in the axial direction, is formed nearly like a cross. The oil groove 7 is formed in such a way as its depth at the end part 7a of the seal part 2 side turns gradually shallow toward the seal part 2 side while its depth at the contrary end part 7b turns gradually shallow toward a screw part 3.
