Japanese Patent JP4425787
Kind Code:
B2
Abstract:
An actuator for actuating a linearly translatable member, such as an engine valve includes a unit trigger actuator, the unit trigger actuator having a trigger being electrically actuatable, a hydraulic cartridge having a selectively translatable component and being operably coupled to the trigger for receiving actuation commands therefrom, the unit trigger actuator being an open loop system. A pivot element is operably coupled to the translatable component and to the engine valve, the pivot element amplifying motion imparted to the pivot element by translatory motion of the piston at the engine valve. A lash adjuster is operably coupled to the pivot element for decoupling the hydraulic cartridge from lash inherent in a plurality of components and assembly of an engine valve arrangement. A method of actuation is further included.
