The invention relates to an electrical drive comprising stationary outer and inner stators (5, 6; 11, 11a) and a rotatably mounted rotor. Said drive is provided with a plurality of permanent magnet elements (14, 34, 54) for generating an energizing flow and at least one electrical field coil (12, 15, 32). The rotor is provided with at least one pot-shaped element (8, 28, 38, 58) which has a cylindrical wall (8a, 28a, 38a, 58a) and a base wall (8b, 28b, 38b, 58b), said base wall (8b, 28b, 38b, 58b) being arranged perpendicularly and the cylindrical wall (8a, 28a, 38a, 58a) being arranged coaxially in relation to the axis of the rotor shaft (1, 39, W). The base wall (8b, 28b, 38b, 58b) is linked with the rotor shaft (1, 39, W) for transmitting a torque. The permanent magnet elements (14) rest against the inside of the cylindrical wall (8a, 28a, 38a, 58a) and are fastened side by side on the rotor of the drive in the peripheral direction. The permanent magnets (14, 34, 54), together with the outer and the inner stator (5, 6; 11, 11a), form magnetic circuits which completely extend through the cylindrical part of the rotor in the radial direction.

The invention relates to an electromagnetic or electrohydraulic valve control device. According to the invention, a sealed chamber (2) is formed above the cylinder head, and the actuators, which are mounted on supports, of at least one part of the inlet and outlet valves are accommodated in said chamber that is sealed from the outside by a cover (11). The cover is at least partially flown around by a coolant having a lower temperature than engine oil or engine cooling water, e.g. by the intake air of the intake tube.

The invention relates to an electromagnet which is provided with a yoke consisting of lamella and having an electric turn and an armature engaging therewith. The yoke is provided with deflection resistant yoke side plates at least on the outer sides of the lamella packet. Said side plates are welded to at least a part of the lamella.

The invention relates to an electromagnetic actuator which actuates a gas exchange valve. Said actuator comprises two electromagnets and an armature which is actuated by the latter and acts upon the gas exchange valve and comprises two spring forces which act in opposing directions upon the armature. The electromagnets have a transformation ratio i = 11/12 of less than 1. The armature and the poles of the electromagnet which are assigned thereto are configured in such a way that the transformation ratio i1 of the contact magnet is greater than the transformation ratio i2 of the break magnet.

The invention relates to an internal combustion engine in which every cylinder is provided with inlet and outlet valves that are actuated by swift electromagnetic actuators. According to the invention, every cylinder is provided with two outlet valves but only one inlet valve.
摘要:
Disclosed is a method for producing an electromagnetic actuator which can, for example, be used to drive the valve of an internal combustion engine. In order to compensate at least extensively for air-gaps caused by deflections in the yoke (1a,2a) of the electromagnets and/or the rotor when the actuator is actuated in the final positions of the rotor (5), said air-gaps are determined and compensated by means of a corresponding profile which is conferred upon the yokes and/or rotor.
