Electromagnetic piston valve actuation device for internal combustion engine

摘要

The actuation element is longitudinally displaceable in the magnetic field of the magnetic coil or magnetic coil unit (3,3') of the piston valve (1). For at least two piston valves which are to be actuated in common, a common magnetic coil or magnetic coil unit is provided and two or more actuation elements (5a,5b) are arranged in their magnetic fields. The actuation elements are guided within oval magnetic cores (8,8') inside the magnetic coils. Multiple actuation elements are arranged adjacent to each other.
