摘要：A cold-formed flat top plunger blank is provided for use in a hydraulic lashadjuster. An end wall at the first end of the plunger body defines a flat top surface that is
cold-formed to final dimensions or net shape. The flat top surface at the first end of theplunger body is configured to engage a flat surface within the mating bore of an enginecylinder head. By configuring the plunger body to have a flat top surface that engages aflat surface disposed within the mating bore of an engine cylinder head, the force appliedto the engine block by the lash adjuster is distributed more evenly, minimizing wear. Theexternal flat top plunger is a unitary component cold-formed to near net shape,including cold-forming to final dimensions the flat top surface and a counterbore.
