  • Method for manufacturing a direct acting hydraulic tappet
    Patent number: 5430934
    Abstract: A method for making a direct acting tappet in which an oil groove and interior structure defining a weld interface are formed in a cupshaped body by a rolling process, the body is heat treated, a web and hub structure is positioned against the weld interface and the resulting assembly is subjected to a localized, capacitive discharge welding process in the weld interface area. The weld interface is formed to a specific shape to enhance the integrity of the weld. Further, a baffle member can be assembled to the web and hub structure prior to its positioning within the body member.
