Patent number: 11008900Abstract: A valvetrain for an internal combustion engine of the type that has a combustion chamber, a moveable valve having a seat formed in the combustion chamber, and a camshaft includes a rocker arm assembly, a pivot providing a fulcrum for a rocker arm of the rocker arm assembly, and a latch assembly. An electrical device mounted to the rocker arm assembly receives power or communicates through a circuit that includes an electrical connection formed by abutment between surfaces of two distinct parts. The rocker arm assembly is operative to move one of the two abutting surfaces relative to the other in response to actuation of the cam follower. Forming an electrical connection through abutting surfaces that are free to undergo relative motion may reduce or eliminate the need to run wires to a mobile portion of the rocker arm assembly.Type: GrantFiled: June 5, 2020Date of Patent: May 18, 2021Assignee: Eaton Intelligent Power LimitedInventors: Petr Liskar, Jiri Cecrle, Dale Arden Stretch, Michael J. Campbell, Tomas Drabek, James Edward McCarthy, Jr., Austin Robert Zurface, Robert Philip Benjey, Eric John Yankovic, Brian Karl Vandeusen, Nicholas Peter Gillette, Michael James Stanton, Thomas Michael Tembreull, Anthony Leon Spoor

Patent number: 10781726Abstract: An internal combustion engine includes a cam-actuated rocker arm assembly with a solenoid-actuated latch that provides for cylinder deactivation or variable valve actuation. The solenoid has an inductance that varies significantly in relation to the position of a latch pin as it translates between latching and non-latching configurations. A sensor is positioned to monitor a current or a voltage in a circuit that includes the solenoid. Diagnostic information relating to the operation of the rocker arm assembly is determined by comparing data collected from the sensor over a first period to data collected from the sensor over a second period.Type: GrantFiled: August 4, 2019Date of Patent: September 22, 2020Assignee: Eaton Intelligent Power LimitedInventors: James Edward McCarthy, Jr., Mark Allan Juds, Douglas Anthony Hughes, Nicholas Peter Gillette, Matthew Richard Busdiecker

Patent number: 10731517Abstract: A valvetrain includes a rocker arm assembly having a rocker arm and an electromagnetic latch assembly. A magnet of the latch assembly is housed within a chamber formed by the rocker arm. The chamber may be a retrofit hydraulic chamber. The magnet may be an electromagnet or a permanent magnet. A flux shifting bi-stable latch provides a sufficiently compact design. Isolation of the magnet within the rocker arm chamber may provide protection from metal particles carried by oil in an operating environment for the rocker arm assembly.Type: GrantFiled: January 22, 2018Date of Patent: August 4, 2020Assignee: Eaton Intelligent Power LimitedInventors: Petr Liskar, Dale Arden Stretch, James Edward McCarthy, Nicholas Peter Gillette, Andrei Dan Radulescu
