More Information
Summary:The utility model discloses a tappet. A metal compact layer is arranged on the outer surface of the body, a self-lubricating layer is arranged outside the metal compact layer, and friction between the tappet and a driving part thereof such as a cam shaft can be reduced as well as friction between the tappet and a tappet hole when the tappet moves up and down, so that the tappet is more wear resistant and longer in service life. The thickness of the self-lubricating layer is smaller than that of the metal compact layer, too small gap between the tappet and the tappet hole when the tappet moves up and down is avoided, and the tappet can move up and down more smoothly.
