Abstract: 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.

Abstract: A valvetrain suitable for an internal combustion engine of a type that includes a combustion chamber, a moveable valve having a seat formed within the combustion chamber, and a camshaft. The valvetrain includes a rocker arm assembly having a rocker arm and an electrical device that either configures the rocker arm assembly or provides position feedback for a part of the rocker arm assembly. The valvetrain includes a framework that fits around a spark plug tube while holding a component of a circuit that includes the electrical device in a position adjacent the rocker arm assembly. The position may place the component in contact with or very close to the rocker arm assembly. This framework structure may effectively utilize the available space under a valve cover while facilitating correct positioning of the component in relation to the rocker arm assembly.

Abstract: A valvetrain includes a rocker arm assembly and a power transfer module that provides power to the rocker arm assembly. The power transfer module includes a mounting frame that positions a resilient contact to abut and slide over a corresponding contact on the rocker arm assembly thereby maintain an electrical connection to the rocker arm assembly during rocker arm assembly operation. In some embodiments the structure facilitates retention of the rocker arm assembly on a pivot. The contact on the rocker arm may be provided by a contact pin. The mounting frame may abut and/or go around a pivot for the rocker arm assembly. A contact frame on the rocker arm may hold conductors of the electrical circuit extending from the contacts.
