Abstract (en)
[origin: US2008035093A1] The invention pertains to a device for controlling the opening and closing of an internal combustion engine valve. This device is characterized in that the magnetic circuit of the electromagnet and/or the plate contains a magnetic material having a remnant magnetization (F<SUB>p</SUB>) when the valve is in position, the remnant magnetization (F<SUB>p</SUB>) being reversible so as to be cancelled when the valve changes position and having a coercive field strength in the range of 10 Oe to 600 Oe.
