Abstract: A finger lever is provided for a valve train of an internal combustion engine. The finger lever comprises an inner lever, at least one arm pivotally coupled to the inner lever, and a coupling device operatively displaceable to control movement of the at least one arm relative to the inner lever. The coupling device includes a slide and a piston disposed in a longitudinal bore of the inner lever, the piston having an entraining slot in which at least part of the slide is received, and at least one biasing member arranged to bias the piston relative to the inner lever. The slide is constructed to be displaced in a coupled position or an uncoupled position. In the coupled position the slide is entrained by the at least one arm, and in the uncoupled position the slide is not entrained by the at least one arm.

Abstract: A method of manufacturing spring pallets of a switchable roller finger follower. The method includes the steps of forming the spring pallets of the roller finger follower as a single unit, forming a material web between the spring pallets, and separating the spring pallets apart from each other. Also, an intermediate assembly of the spring pallets of the roller finger follower is disclosed. The intermediate assembly includes a first spring pallet, a second spring pallet, and a material web which extends between the spring pallets, and adjoins the spring pallets together. Further, a method of manufacturing an inner arm of the switchable roller finger follower is disclosed in which the inner arm is formed by sheet metal, preferably by stamping.

Abstract: A finger follower having an inner and outer body and a torsional lost motion spring acting between the bodies is provided. A roller cam follower is connected to the inner body. The inner body is switchable from a fixed state, in which it moves with the outer body to transfer a cam lift to a valve stem, to a released state, in which the inner body can move relative to the outer body so that the cam lift is not transferred to the valve stem. A separate valve pallet that acts on the valve stem is press fit or otherwise rotationally fixed on a pivot pin connecting the inner and outer bodies.
