摘要： A method of increasing a cast-off speed of an armature from a pole of an electromagnet of an electromagnetic actuator, includes the following steps: holding the armature at the pole against a force of a resetting device by maintaining an electric holding current flow through a coil of the electromagnet; and launching the armature from the pole by switching off the holding current; and at a predetermined moment during a release period of the armature from the pole, passing a cast-off current for a predetermined period through the coil. The cast-off current has a polarity opposite to the polarity of the holding current.

摘要： Motion recognition processes are disclosed, in particular for regulating the impact speed of an armature on an electromagnetic actuator with at least one electromagnet having at least one pole face (4) and connected to a controllable power supply, and with an armature (5) connected to a regulating element to be actuated which when power is supplied to the electromagnet, is moved against the force of a restoring spring (7) in the direction of the pole face of the electromagnet from a first switching position to a second switching position in which it stops against the pole face. At least one sensor (11) detects in a defined air gap zone of the pole face a progressive attenuation of the magnetic field as the armature approaches and generates a corresponding signal.

摘要： An electromagnetic actuator includes an electromagnet having a pole face, an energized state for generating an electromagnetic force and a de-energized state; and an armature movable towards and away from the pole face in a travel path extending from a first end position remote from the pole face to a second end position at the pole face. The armature assumes the second end position in the energized state of the electromagnet. A return spring urges the armature away from the pole face and toward the first end position. Further, a fluid damping unit is provided for braking a motion of the armature along a terminal portion of its travel path shortly before its arrival into at least one of the end positions for effecting a soft arrival of the armature into such end position.

摘要： A method for producing a metal component which is made up of at least two partial elements with differing material properties is distinguished in that a first partial element made of a steel material, which can be tempered, is preassembled in a recess in a second partial element made of a magnetic iron material of low retentivity. A copper based solder is applied to the preassembled component at the recess in the transition area between the first partial element and the second partial element. Thereafter, the component is heated to a temperature which lies above the melting temperature of the solder. After the liquid solder has been distributed in a contact area of the two partial elements, the component is cooled. The component is then brought at least once to the tempering temperature of the steel material of the first partial element, is maintained at this temperature for a predetermined length of time and then is completely cooled.

摘要： An actuator assembly for operating a setting member includes an actuator body undergoing a dimensional change upon applying electrical energy thereto; a preliminary pressure chamber for accommodating liquid; a diaphragm sealing the preliminary pressure chamber and being displaceable by the actuator body; a valve member carried by the diaphragm; a transfer chamber for accommodating liquid; and a displaceable plate body disposed in the preliminary pressure chamber and sealingly bounding the transfer chamber. The diaphragm, as it is moved by the actuator body, displaces the plate body. A displaceable piston body sealingly bounds the transfer chamber and has a surface which is smaller than the surface of the plate body, whereby the plate body--with the intermediary of the liquid--displaces the piston body to a greater extent than the displacement of the plate body. The piston body, as it moves, displaces the setting member. A valve opening provided in the plate body is closed or opened by the valve member carried by the diaphragm. In the open position of the valve member, the valve opening establishes a hydraulic communication between the preliminary pressure chamber and the transfer chamber.

摘要： A method of controlling a piston-type internal-combustion engine having a cylinder, first and second intake ports opening into the cylinder, as well as first and second intake valves disposed in the first and second intake ports, respectively, for controlling admission of fuel into the cylinder. The method includes injecting fuel simultaneously into the first and second intake ports during operational cycles of the cylinder; at low engine load operating solely one of the first and second intake valves, while maintaining the other of the first and second intake valves inoperative. The operating step is alternated such that the first and second intake valves are alternatingly in an operative and in an inoperative state during consecutive operational cycles of the cylinder.

摘要： A method of operating a cylinder valve of an internal-combustion engine with an electromagnetic actuator for moving the cylinder valve into opposite open and closed valve end positions includes the steps of energizing an electromagnet of the actuator for generating an electromagnetic force for moving an armature of the actuator toward a pole face of the electromagnet against the force of a return spring; after the armature enters a zone adjacent the pole face of the electromagnet, applying to the armature an additional force opposing the electromagnetic force of the electromagnet; dimensioning the additional force such that an equilibrium between the electromagnetic force of the electromagnet and the increased opposing force of the return spring is situated at a location shortly before the armature enters into engagement with the pole face of the electromagnet; and after the armature reaches the location of force equilibrium, controlling a current supply to the electromagnet such that the armature reaches the pole face of the electromagnet with a predeterminable velocity.

摘要： A method of adjusting the position of rest of an armature of an electromagnetic actuator, reciprocated against the force of resetting springs by an alternating energization of two spaced electromagnets; the position of rest being assumed by the armature in the de-energized state of the two electromagnets. The method includes the steps of detecting and determining actual values of an impact indicator representing an impact behavior of the armature as the armature impacts on the pole face of the capturing electromagnet; comparing the actual values derived from both electromagnets with predetermined desired values to form deviation values between the actual and the desired values; and, if deviation values are present, shifting the position of rest of the armature by an adjusting device until the actual values derived from both electromagnets correspond to a predetermined desired value.
