Abstract
A switchable roller finger follower including a combined lost motion spring and hydraulic lash adjuster clip is provided. The switchable roller finger follower includes at least one spring having two coiled spring portions. Each of the two coiled spring portions is wrapped around a respective spring holding pin formed on an inner elongated body. Each one of the at least two coiled spring portions includes a first leg and a second leg. The first legs each extend from a respective one of the two coiled spring portions to engage a spring pallet formed on an outer elongated body. The second legs each contact a bottom portion of the inner elongated body in proximity to a socket portion to act as a retainer for retaining a hydraulic lash adjuster to the inner elongated body.
