Abstract: A switching roller finger follower (SRFF) assembly for valve actuation comprises an outer arm, an inner arm, an inner roller, a bearing axle and a pair of outer rollers. The outer arm is pivotally coupled to a pivot axle. The inner arm is at least partially disposed within the outer arm and pivotally coupled to the pivot axle. The inner roller assembly comprise a bushing and an outer ring. The bushing defines a curved slot therein. The bushing is fixed to the inner arm. The outer ring is configured to rotate around the bushing. The bearing axle extends through the curved slot. The pair of outer rollers are disposed on each end of the bearing axle.

Abstract: A switching rocker arm assembly constructed in accordance to one example of the present disclosure can include an outer arm, an inner arm, a pivot axle, a bearing axle, a first torsional bearing axle spring and a second torsional bearing axle spring. The outer arm can have a first outer side arm and a second outer side arm. The outer arm can further include first and second torsional spring mounts. The inner arm can be disposed between the first and second outer side arms. The pivot axle can support the inner and outer arm for relative pivotal movement therearound. The bearing axle can support a bearing. The first torsional bearing axle spring can be mounted around the first torsional spring mount and have a first end engaged to the bearing axle and a second end engaged to the outer arm. The first end extends inboard relative to the second end.
