Patent number: 11143064Abstract: In an electromagnetic latch assembly of a type that includes an armature, an electromagnet operative to actuate the armature, a latch pin, and a rigid metal structure that supports both the electromagnet and the latch pin, the latch pin is attached to the armature through a bendable connection. The electromagnet may be mounted to or housed within the metal structure. The latch pin may protrude from the rigid metal structure and may be guided by the metal structure. The bendable connection couples translation of the armature to translation of the latch pin while allowing the two parts to move independently to some degree. The bendable connection may reduce forces on the armature that could cause the armature to bend or stick. Those forces may result from misalignment between the latch pin and the armature or from the latch pin being driven off axis under load.Type: GrantFiled: August 12, 2020Date of Patent: October 12, 2021Assignee: Eaton Intelligent Power LimitedInventors: Austin Robert Zurface, Dale Arden Stretch, Brian Karl Vandeusen

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.

Patent number: 10731516Abstract: A valvetrain for an internal combustion engine includes a camshaft and a rocker arm assembly. The rocker arm assembly includes an electrical device, a rocker arm, and a cam follower. A contact held to the rocker arm abuts a spring attached to a component distinct from the rocker arm assembly to form an interface. The electrical device is powered through the interface. The spring slides over the contact as the rocker arm assembly pivots to actuate a moveable valve. The interface is formed near a pivot axis whereby the motion undergone by the interface is much less than the motion undergone by points on the rocker arm assembly more distal from the axis. Keeping the interface proximate the pivot axis and leaving the spring free to slide over the contact reducing the extent to which the spring undergoes movement and wear during valvetrain operation.Type: GrantFiled: July 11, 2019Date of Patent: August 4, 2020Assignee: Eaton Intelligent Power LimitedInventors: Andrew Lee, Michael J.

Publication number: 20200063609Abstract: A method of precision manufacture of an outer arm of a rocker arm assembly is performed by determining structures of a rough outer arm that would require precision processing and locations to support the structures as they are processed. Starting with at least one structure requiring precision processing, locations on the outer arm close to the structure to hold the outer arm during processing are determined that would cause minimal distortion of the outer arm during processing. The outer arm is then provided with clamping lobes at these locations. The clamping lobes of the outer arm are clamping into a fixture for manufacturing. The slider pad may now be precision ground while the outer arm is clamped in the fixture with minimal risk of distortion of the outer arm.Type: ApplicationFiled: September 6, 2019Publication date: February 27, 2020Inventors: Austin Robert Zurface, Tony Eric Gordon, Andrei Dan Radulescu, Otto Jerome Schultheis
