    摘要： On a known electromagnetic actuator for valve control of an internal combustion engine an armature (1) is moved by magnetic force between the pole faces (21, 31) of an opening magnet (2) and a closing magnet (3) to activate an intake/exhaust valve (5). Owing to the work that has to be done when the intake/exhaust valve (5) is opened in order to counteract the high internal gas pressure in the combustion chamber the opening operation takes longer than the closing operation. The disclosed actuator permits faster opening of the intake/exhaust valve (5), in that the magnetic force exerted by the opening magnet (2) is increased for large stroke lengths (d.sub.o) in comparison with the magnetic force exerted by the closing magnet (3) on the armature (1) in conjunction with the same stroke length (d.sub.s) by the provision of a two-section connecting sleeve (7) enclosing the space between the pole faces (21, 31). This connecting sleeve (7) consists of a ferromagnetic sleeve section (70) attached to the opening magnet (2) and a nonferromagnetic sleeve section (71) attached to the closing magnet (3).

    摘要： The invention relates to an electric drive unit comprising an electronic control module and an electric motor. The cooling of the components of the electric drive unit should be effected in a simple manner. To this end, the hub of the impeller wheel, which is situated on the rotation axis of the electric motor and provided for producing a working air flow, has a two-walled design, whereby a hub inner space is formed between the outer wall and the inner wall of the hub of the impeller wheel. At least one cooling surface of the cooling body, said surface being in contact with components of the electronic control module, projects into the hub inner space. A gap communicating with the hub inner space, is formed between the hub of the impeller wheel and a carrier section which supports the electronic control module and the electric motor. In addition, through-holes communicating with the hub inner space are provided in at least one component of the electric drive unit. When the electric drive unit operates and the impeller wheel is in motion an air flow between the gap and the through-holes is established. The invention also relates to an electric drive unit with a fan motor.

    摘要： An electric drive unit includes an electric motor for driving a fan. The motor has an electronic control module. An impeller wheel for producing a working air flow is mounted by bearings on an axle of the electric motor. The hub of the impeller wheel has at least one preferably two walls enclosing a cooling space or cooling space portions. At least one cooling surface of a cooling body is in contact with components of the electronic control module and projects into the cooling space. A gap formed between the hub of the impeller wheel and a carrier section communicates with an inner hub space. Holes (43, 322) communicating with the hub inner space are provided in at least one component of the electric drive unit. When the impeller wheel rotes a convection cooling air flow is established between the gap and the holes.

    摘要： A housing for retaining an electronic component, including a lid and a lower part made of synthetic material, wherein the lid is joined in a force-fit manner to the lower part by clamping geometry, and in order to affix the electronic component in position, the lid applies a specified force (F) to the electronic component after being joined to the lower part due to its design. Here, the lid is designed in such a manner that the force (F) applied lies within a specified force range (B), and that the clamping geometry comprises a groove on the lower part and a ridge on the lid which grips into the groove, wherein a clamp web on the lower part or on the lid is arranged in such a manner that the lid is removably clamped to the lower part after being joined to the lower part with a force (F) which acts parallel to the clamping force (KF).
