Abstract: A method of cold-forming a ball plunger blank includes providing a slug having first and second ends and backward extruding the slug at its first end to form a cavity that is defined by a wall. The method further includes forming a generally ball-shaped outer surface at the second end of the slug to final dimensions. The method also includes upsetting at least a portion of the wall to form a shoulder that at least partially closes the cavity and defines a ball seat surface to final dimensions.

Abstract: A cold-formed flat top plunger blank is provided for use in a hydraulic lash adjuster. 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 the plunger body is configured to engage a flat surface within the mating bore of an engine cylinder head. By configuring the plunger body to have a flat top surface that engages a flat surface disposed within the mating bore of an engine cylinder head, the force applied to the engine block by the lash adjuster is distributed more evenly, minimizing wear. The external 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.

Abstract: A cold-formed ball plunger blank is provided for use in manufacturing a finished ball plunger used in a hydraulic lash adjuster that includes a check valve assembly having a check ball and a retainer. The ball plunger blank includes a cup-shaped member that extends from a first end to a second end along a longitudinal axis. The cup-shaped member includes a ball portion adjacent the first end of the member and a body portion adjacent the second end of the member. The body portion has a cavity disposed therein, a counterbore extending from the second end of the body towards the first end of the member, and a shoulder that separates the cavity from the counterbore and at least partially closes the cavity. The shoulder defines a ball seat surface configured to receive the check ball and a retainer receiving surface configured to receive the retainer, wherein the ball seat surface and the retainer receiving surface are to sized to the final dimensions of the finished ball plunger. A method of cold-forming a ball plunger blank including providing a slug having first and second ends, backward extruding the slug at its first end to form a cavity that is defined by a wall, forming a generally ball-shaped outer surface at the second end of the slug to final dimensions, and upsetting at least a portion of the wall to form a shoulder that at least partially closes the cavity and defines a ball seat surface to its final dimensions.
