Abstract

PURPOSE: To improve the abrasion resistance of a tappet for a control valve by fitting a shim consisting of abrasion resistant sintered alloys inhe tappet barrel and forming a concave section at the center of tappet barrel or the shim engagement surface.
CONSTITUTION: A shim 2 consisting of abrasion resistant sintered alloys is fit in a tappet barrel 3. A concave section 6 is formed at the center of the tappet barrel 3 or a recess section 7 is formed at the center of the shim 2. The shim 2 contains carbon and chrome besides iron and one or two or more types of base reinforced elements Ni, Mo, Co, and Cu. Further, it contains one or two or more types of P, B, and Si which perform liquid-phase sintering and sintered holes. As described above, the shim 2 can show abrasion resistance.
