摘要： An electromagnetic actuator for use in locking mechanisms comprises a housing, a plurality of coils and an armature which is linearly moveable relative to the housing between two end-of-travel positions by selectively energising the coils of the actuator. The actuator includes a fail-safe mechanism which is operable to urge the armature towards one of the two end-of-travel positions.

摘要： A rotary electromagnetic actuator includes a biasing assembly for applying a torque to its rotor. Such an actuator may be used to operate a poppet valve of an internal combustion engine. The biasing assembly is moveable between a first configuration and a second configuration, wherein the biasing assembly stores a higher amount of potential energy in its second configuration than in its first configuration. The apparatus includes a latching mechanism for selectively latching the biasing assembly in its second configuration.

摘要： A rotary electromagnetic actuator is provided which is suitable for opening and closing a valve for example. The actuator comprises a rotor, a stator, and a biasing arrangement for applying a torque to the rotor during at least part of its rotation. A plurality of stable rest positions for the rotor are defined by forces acting on the rotor and the actuator is controllable to move the rotor from one stable rest position to another. The torque applied by the biasing arrangement varies with the rotational position of the rotor such that at a primary rest position and at least a second rest position, it is sufficiently low to enable selection of those positions, and then it increases beyond the second rest position.

摘要： A valve control system is provided for an internal combustion engine, the engine having at least one cylinder with at least one set of at least two valves. All the valves in the set are either inlet valves or exhaust valves, and the system is configured to selectively operate the set of valves in a single valve mode of operation during which only one valve of the set is open at any time.

摘要： A linkage for coupling between an actuator and a valve in an engine valve actuation assembly. The linkage provides some compliance in the operation of the linkage to close the valve. The linkage comprises a rocker having a rigid body portion, the body portion including a pivot axis about which it is rotatable, and a link mount for coupling to a valve link arm. The link mount is moveable from a rest position relative to the body portion, and the link mount is urged back towards its rest position when displaced from its rest position relative to the body portion.

摘要： A valve control system for an internal combustion engine, the engine having at least one cylinder with at least one intake or exhaust valve and a piston and the valve being operable independently of the rotation of the engine crankshaft. The system is configured to generate a control signal that controls a preconditioning actuation cycle of an actuator prior to a first combustion cycle of the engine, receive a feedback signal relating to an operating condition of the actuator during the preconditioning actuation cycle, and generate a modified control signal that controls a combustion actuation cycle of the actuator, modified with reference to the feedback signal. This recalibration of the valve control signals allows the current operating conditions of the valve train to be taken into account before the first combustion cycle of the engine.
