ABSTRACT:
A ceramic valve seat is disclosed herein. A face portion of the valve seat at which the valve seat is to contact with a valve is made of a ceramic material. At least edge portions of the valve-contacting face portion of the valve seat are rounded. By so constructing, impact force due to contact between the valve and the valve seat and stress concentration can be mitigated.
