Abstract

The actuator has two polarized electromagnets (18, 26), each with a permanent magnet to maintain a magnetic chuck of a valve when the valve is in closed position in the absence of current in a coil of the electromagnet. A defluxing current opposing the effect of the permanent magnet is applied to the coil of either of the electromagnets to move the valve from open to closed position or inversely. A spring permits switching of the valve. An independent claim is also included for an engine comprising a valve actuator.
