Patent number: 11891923Abstract: A valvetrain for an internal combustion engine includes a camshaft, an electromagnetic latch assembly, a rocker shaft, and a rocker arm assembly. The rocker arm assembly may include a cam follower configured to engage a cam mounted on the camshaft as the camshaft rotates and a rocker arm configured to rotate on the rocker shaft. The electromagnetic latch assembly may include a pin translatable between a first position and a second position and an electromagnet that causes the pin to actuate. The movement of the pin may provide mode switching for a switching rocker arm, a cylinder deactivating rocker arm, or an engine brake rocker arm. The electromagnet is powered by a circuit that passes through the rocker shaft. The electromagnet may be mounted to the rocker shaft. Running the circuit through the rocker shaft allows the electromagnet to be powered with wiring that remains stationary.Type: GrantFiled: September 10, 2020Date of Patent: February 6, 2024Assignee: EATON INTELLIGENT POWER LIMITEDInventors: Adam Boden, Anthony Leon Spoor

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: 10590809Abstract: A valve train assembly having a valve train carrier including a body having a cartridge cavity formed in the body, a hydraulic lash adjuster adjustment (HLA) assembly, and a cartridge removably disposed in the cartridge cavity. The cartridge includes a main body defining an inner bore, wherein the HLA assembly is disposed in the inner bore, and the cartridge is sized and shaped for insertion into the cartridge cavity formed in an underside of the valve train carrier. The cartridge is configured to have a valve train lash set prior to insertion into the cartridge cavity. A rocker arm assembly includes a body configured to engage the hydraulic lash adjustment (HLA) assembly, an end having a socket formed therein, and an e-foot extending through the socket and coupled to the end, the e-foot configured to maintain substantially flat contact with a top surface of an engine valve.Type: GrantFiled: October 31, 2017Date of Patent: March 17, 2020Assignee: Eaton CorporationInventors: Eric John Yankovic, Majo Cecur, Debra Lynn McFadden, Andrei Dan Radulescu, Anthony Leon Spoor, Douglas Wright

Patent number: 10082050Abstract: An anti-rotation guide for a lifter in an overhead valve valvetrain. The anti-rotation guide includes a plug having two lobes connected through a neck region. A first lobe of the plug is held within a bore in the lifter. The bore forms an opening at the edge of the lifter through which the neck of the plug emerges. The bore in the lifter accommodates a first lobe of the plug that is wider than the opening in the edge of the lifter, whereby the plug is shaped to prevent its slipping from the lifter through the opening. The lifter reciprocates in a first bore in the cylinder head. The second lobe of the plug extends outward from the lifter into a second bore formed in the cylinder head and adjoining the first bore. The second lobe reciprocates in the second bore and limits rotation of the lifter.Type: GrantFiled: September 13, 2016Date of Patent: September 25, 2018Assignee: Eaton Intelligent Power LimitedInventors: Douglas John Nielsen, Anthony Leon Spoor, Robert D.
