Abstract
PURPOSE: To prevent a deformation of a valve seat by applying a filler on the external periphery of the valve seat or the inwall of a cylinder head into which the valve seat is inserted under pressure, thereby increasing fitness of the valve seat and the cylinder head.
CONSTITUTION: Before a valve seat 2 is inserted into a seat hole 4 in a cylinder head 1 at a cold state, a filler 6 is applied on the internal periphery and the bottom face of the seat hole 4 in the cylinder head 1. As the filler 6, a heat-resisting and effectively heat-transferring agent is used. The filler 6 flows downwards to the bottom face of the seat hole 4, because it is inclined at an angle θ. Thereby, the valve seat 2 and the cylinder head 1 contact more tightly and a higher heat transfer rate may restrict a heat-caused deformation of the valve seat 2.
