Abstract
PURPOSE: To make the surface of a valve seat smooth by pressing a solid body of the same shape as that of the valve seal surface against the surface of a synthetic resin valve seat.
CONSTITUTION: Valve seat 11 is fitted to the upper surface of lower support 10, made of metal. The inner wall of the depression on the upper surface of lower support 10 is given a smooth finish. The inner diameter of its surrounding wall is made nearly the same as the outer diameter of valve seat 11 and is given a fine finish. Spherical body 13, made of metal, is mounted on valve seat surface 12 of valve seat 11. This spherical body 13 is hard and its surface is given a smooth finish. Spherical body 13 has the same radius of curvature as the valve on which valve seat 11 is to be fitted. On spherical body 13 are placed upper support 10' and valve seat 11', which are similar to lower support 10 and valve seat 11. When they are compressed from both sides of upper and lower supports 10', 10, valve seat surfaces 12, 12' of valve seats 11, 11' are made smooth.
