Abstract: A rocker arm assembly can comprise a main rocker arm and a latch assembly. A latching arm can control the latch assembly and thereby control the extent to which a secondary rocker arm acts on the main rocker arm. The main rocker arm can comprise a main body configured to rotate around a rocker shaft, a valve end extending from the main body, a reaction end extending from the main body, and a latch bore. A bias pin can extend from the main body. The latch assembly can be configured to selectively rotate in the latch bore. The latch assembly can comprise a first latch end comprising a switch plate configured to receive actuation force on a first side and to receive bias force from the bias pin on a second side. A second latch end can comprise a first latch seat and a second latch seat.

Abstract: A switching rocker arm assembly constructed in accordance to one example of the present teachings includes an outer arm, an inner arm, a bearing axle and a pivot axle. The outer arm can have a first outer side arm and a second outer side arm. The outer arm can define outer bores. The inner arm can have a first inner side arm and a second inner side arm. The inner arm can be disposed between the first and second outer side arms. The inner arm can define inner bores. The bearing axle can support a bearing. One of the bearing axle and pivot axle comprises (i) a central axle body having a central centerline, (ii) a first axle end body having a first centerline and (iii) a second axle end body having a second centerline. The central centerline is offset from at least one of the first and second centerlines.

Abstract: A tappet having a contiguous body, an outer wall and transverse web. The outer wall defines a cylindrically-shaped outer surface and a recess. The recess is disposed within cylindrical surface of the body. An alignment member is press-fit between two staked ends of the recess, which engage opposite sides of the alignment member. The alignment member extends outwardly from the cylindrically-shaped surface. A roller is mounted to the contiguous body at the cam contacting end of the tappet.
