Patent number: 11788439Abstract: A rocker arm includes an outer arm having a first side and a second side, an inner arm positioned between the first side and the second side of the outer arm, a pivot axle pivotally coupling the inner arm to the outer arm at a first end of the inner arm and a first end of the outer arm, and a latch pin having a first position and a second position. The latch pin in the first position pivotally fixes the inner arm to the outer arm at a second end of each of the inner arm and a second end of the outer arm, and in the second position allows the inner arm and the outer arm to pivot independently. Two lost motion springs are respectively secured to mounts provided on the outer arm.Type: GrantFiled: December 21, 2020Date of Patent: October 17, 2023Assignee: Eaton Intelligent Power LimitedInventors: Andrei Dan Radulescu, Austin Robert Zurface, James R. Sheren, Anthony L. Spoor, Luigi Lia, Philip Michael Kline

Patent number: 10570786Abstract: A durable system for controlling variable valve actuation of an engine valve corresponding to a cylinder of an automobile engine. The system includes first and second crowned cams having first and second lift profiles and a rocker arm assembly. The rocker assembly includes a first arm having an end connected to said engine valve, having a high impact roller following the first crowned cam operating the engine valves according to a first lift profile. The rocker arm assembly also includes a second arm having durable slider pads riding on the second crowned cam to operate said engine valve according to a second lift profile. A latch secures the second arm relative to the first arm when in a latched position causing the valve to operate according to a second lift profile. The valve operates according to a first lift profile when the latch is not in the latched position.Type: GrantFiled: December 4, 2017Date of Patent: February 25, 2020Assignee: EATON INTELLIGENT POWER LIMITEDInventors: Otto Jerome Schultheis, Tony Eric Gordon, Mark Joseph Birler, Philip Michael Kline, James E.

Patent number: 9995183Abstract: Tools and methods for indenting and assembling a switching rocker arm assembly having an inner arm, an outer arm and a latch. The tools and methods are directed to eliminating requirements for matched sets of components of rocker arm assemblies so that the assembled indented parts have desired latch lash tolerances. The tools used include fixtures and clamps for indenting kidney-bean shaped passages in an outer arm that mount a pivot axle of the outer arm. The tools used may also include a fixture and clamps for indenting a latch shelf of the inner arm. Indenting the inner arm and outer arm using these methods and fixtures results in switching rocker arm assemblies that fit together, and when assembled into a valve, have a desired latch lash.Type: GrantFiled: June 2, 2016Date of Patent: June 12, 2018Assignee: EATON CORPORATIONInventors: James R.
