ABSTRACT:
A valve operating device for the intake or exhaust valves of an internal combustion engine wherein a plurality of cam followers are disposed adjacent to each other for operation by different cams in mutually different modes dependent on the speed of rotation of a camshaft. A selective coupling mechanism disposed in and between the cam followers has switching pins movable between a connecting position in which the cam followers are interconnected and a disconnecting position in which the cam followers are disconnected. An oil passage is provided in one or more of the cam followers and the switching pin therein is arranged to control the rate of flow of oil through the oil passage defined in that cam follower in response to movement of the switching pin between the connecting and disconnecting positions. The oil supplied through the oil passage is used for lubricating the cam and cam following sliding surfaces in one embodiment and for operating hydraulic valve lash adjusters in another embodiment.
