An electromagnetic valve actuator for internal combustion engines, includes an electromagnet and a mobile magnetic plate intended to come into contact with a part of the electromagnet. At least one stop is located on the electromagnet or on the plate to limit the contact surface between the plate and the electromagnet. The actuator the electromagnet includes a magnet in its magnetic circuit.

Electromechanical valve actuator for internal combustion engines and internal combustion engine equipped with such an actuator

An electromechanical valve actuator for internal combustion engines, equipped with a polarized electromagnet and with a magnetic plate switches between a first position close to the electromagnet and a second position remote from the electromagnet, the switching times between these positions being determined depending on the operating state of the engine. The actuator supplies the electromagnet with a variable attracting current in the course of the approach of the plate to the electromagnet.

An electromechanical valve actuator for internal combustion engines is equipped with a polarized electromagnet exerting a magnetic action on a magnetic plate that is subject to a mechanical restoring action, which action can compensate for the mechanical action and maintain the plate in a distant position from the electromagnet. The actuator ensures that the displacements of the plate are controlled solely by this electromagnet and the mechanical restoring action such that the plate performs shuttle movements beginning from the distant position.

An electromechanical valve control actuator for internal combustion engines, includes an electromagnet with a magnet and a mobile magnetic plate moving into the vicinity of the electromagnet. The magnet is located on a surface of the electromagnet opposite the plate. The actuator includes an E-shaped magnetic circuit, and the magnet is located at the end of a branch of this E-shaped circuit.
