Full variable stroke valve controller for combustion engine in automobile, has eccentric and supporting shafts rotated at pivot point of intermediate lever during valve opening duration in order to vary valve lift

摘要

The controller has a poppet valve (HV) which is actuated by a roller lever (SH). A rotating camshaft (NW) is mounted on an upstream intermediate lever (ZH) connected to roller lever. The eccentric shaft (EW) is supported on adjustable rocker (VS) that is connected to upstream intermediate lever on which a supporting shaft (SW) is mounted. The eccentric shaft and supporting shaft are rotated at pivot point (C4) of intermediate lever in movement direction of circular arc (KB) during valve opening duration in order to vary the valve lift.
