DIRECT-ACTING SOLENOID HAVING VARIABLE TRIGGERING TIMING FOR ELECTRO-MECHANICAL VALVETRAIN AND ACTUATION LEVERS FOR SWITCHING ROCKER ARMS

Systems, methods, and control systems for a switching rocker arm assembly are disclosed. A switching rocker arm () engages a valve (), the switching rocker arm () is movable by contact with a cam () having a lift portion () and a base circle (). The switching rocker arm () comprises an inner arm (), an outer arm () pivotably secured to the inner arm () and having a latch bore, and a latch pin () selectively movable between a first position where the latch pin () does not contact the inner arm (), and a second position wherein the latch pin () contacts the inner arm (). A solenoid assembly () is energized while the rocker arm is in contact with the lift portion () of the cam. The solenoid assembly is direct-acting and overhead and is calibratable with respect to the rocker arm.
