Embodiment Construction

[0025] first reference figure 1 , an exemplary shifted rocker arm constructed in accordance with an example of the present invention is shown and generally designated by the reference numeral 10 . The switching rocker arm assembly 10 may be a compact cam-actuated single lobe deactivation (CDA-1L) switching rocker arm mounted on a piston-driven internal combustion engine, the single lobe deactivation switching rocker arm consisting of two Combination actuation of the feed hydraulic lash adjuster (DFHLA) 12 and oil control valve (OCV) 16 . The shifted rocker arm assembly 10 is engageable with a single lobe cam 20 . The shifted rocker arm assembly 10 may include an inner arm 22 and an outer arm 24 . The default configuration is in the normal lift (locked) position where the inner arm 22 and outer arm 24 are locked together such that the engine valve 26 is open and the cylinder is allowed to operate as in a standard valve train. DFHLA12 has two ports. Lower oil port 28 provide...

Description

[0001] Cross References to Related Applications [0002] This application claims International Application No. PCT / US2014 / 019870, filed March 3, 2014, U.S. Patent Application No. 61 / 986,976, filed May 1, 2014, and U.S. Priority of Patent Application No. 62 / 081,306. The disclosures of the aforementioned applications are incorporated herein by reference. technical field [0003] The present invention relates generally to a shifted roller finger follower or rocker arm in an internal combustion engine, and more particularly to a method of making or assembling the inner arm, outer arm and latch of a shifted rocker arm. Background technique [0004] A switchable roller thumbwheel follower or rocker arm allows the actuation of the valve to be controlled by alternating between two or more states. In some examples, the rocker arm may include multiple arms, such as an inner arm and an outer arm. In some cases, the arms can engage different cam lobes, such as low-lift lobes, high-li...
