Publication number: 20080236532Abstract: A cam-follower rocker arm is provided comprising a flat single plate body containing an axle that extends perpendicular from the vertical wall area for making contact with a valve and a second pivot point axle. The pivot point for the cam-follower rocker arm may be located centrally or at the end of the cam-follower rocker arm that is opposite the cam-follower rocker arm valve arm. An external cam-follower bearing is mounted on the axle and extends on each side of the flat plate wall. The cam-follower rocker arm of the invention is characterized by a relatively reduced mass and has a stiffness that exceeds limits achieved by known prior art designs for an overhead cam and cam-follower valve train; the gain in stiffness being attributed to the body's flat plate cross-section relative to conventional prior art cam-follower rocker arms that have a U-shape or a dual wall cross-section.Type: ApplicationFiled: June 10, 2008Publication date: October 2, 2008Inventors: Scott P. Smith, Blaine R. Lingenfelter, John E. Brune

Patent number: 5172661Abstract: A phase change device of the type wherein a phase change is effected between an input member and an output member in response to the axial movement of an advancing element interconnecting the input member and the output member, and wherein such axial movement is effected by retarding the rotation of a drum member engaged with the advancing element. A grooved thread is formed in the drum member, and a plurality of balls carried in slots formed in the output member are received in the thread and in helical grooves formed in the input member to effect the relative rotation between the input and output members as the balls advance axially along the thread in response to retardation of the drum member.Type: GrantFiled: March 20, 1992Date of Patent: December 22, 1992Assignee: Eaton CorporationInventors: John E. Brune, Darryl J. Muir, James K. Day
