Abstract

The present invention provides an actuator assembly for operating a cylinder valve of an internal combustion engine. The actuator assembly achieves fast response times by utilizing a solenoid actuator that contains an armature element formed of a powder metal. A valve system that utilizes two of the actuator assemblies in conjunction with a cylinder valve is also provided.
