  • Publication number: 20030137291
    Abstract: An angle sensor includes at least one magnetoelectrical converter element (6, 7) and a magnetic circuit having at least one flux guide piece (2, 3, 4, 8; 12) and at least one magnet (5). By the motion of an element, an influence, measurable by the converter element (6, 7), on the magnetic flux is brought about. A first flux guide piece (2, 3, 4), the at least one magnet (5), and at least one converter element (6, 7) are located in an unaltered position relative to one another during the angle measurement, and a second flux guide piece (8) is rotatable relative to these parts (3, 4, 5, 6, 7). The magnetic field is evaluatable by the converter element (6, 7), and a variation in the magnetic field can be brought about by a variation in the air gap in the magnetic circuit during the rotation of the second flux guide piece (8).

  • Patent number: 5690070
    Abstract: An apparatus for governing an idling rpm of an internal combustion engine by controlling a quantity of operating fluid that can be supplied to the engine from an operating fluid source via at least two flow lines. A first valve opening cross section at a first valve opening is controlled by a first valve closing member, and a second valve opening cross section and a second valve opening is controlled by a second valve closing member. The first and second valve closing members are adjustable by an adjusting drive in such a manner that the first valve opening and the second valve opening are disposed parallel to one another between the operating medium source and the intake conduit of the engine. The valve closing members are coupled in such a way that upon their actuation, the first valve closing member always uncovers a flow cross section at the first valve opening first, and only then does the second valve closing member uncover a flow cross section at the second valve opening.

  • Patent number: 5554901
    Abstract: A known servo-drive including a stator which is formed with two-component design or the exciter winding has to be attached directly to the stator, which is associated with a costly production method. The new servo-drive is to permit easy and cost-effective manufacture with favorable actuation properties. The stator of the servo-drive includes in the region of the poles, weak points which are formed either by recesses or by gaps. An induction core includes a winding which is inserted into a yoke constructed on the stator by which a magnetic field can be induced in the stator. The alternating combination of sheet-metal laminas having gaps and recesses permits the torque/rotary angle characteristic of the servo-drive to be optimized with favorable production properties. The servo-drive for rotary angle adjustment of an actuator is used for example to control the opening cross-section of a medium-conducting flow line in internal combustion engines for the purpose of controlling idling speed.

  • Patent number: 5415714
    Abstract: A method for positionally securing two components together, in which a hollow body is introduced into the two components. Once the final position of the components relative to one another has been established, the hollow body is driven directly into the second component with the application of axial pressure and sonic energy. The method is suitable for employment with thermoplastic components whose relative position to one another is known beforehand, an example being in the assembly of housing parts of a rotary adjuster for controlling a flow cross section in internal combustion engines.

  • Patent number: 5283495
    Abstract: A rotary actuator for setting the rotation angle of control elements, especially of a throttle device which determines the flow cross-section in a line through which flow passes, for internal-combustion engines, having an electric actuating motor with a two-pole stator, stator winding and two-pole permanent-magnet rotor. In order to achieve a compact construction and manufacture which is easy in production-engineering terms, the stator poles are constructed as claw poles which are connected on opposite end sides in each case to an annular jacket for the magnetic return path, which jacket surrounds the claw poles with a radial gap. The stator winding is located as an annular coil in the annular space between the annular jacket and the claw poles.

  • Patent number: 5275373
    Abstract: A device, in particular for controlling a throttle cross-section in an operating fluid carrying line of an internal combustion engine, has a housing provided with a bore and a throttle aperture, an inlet connecting piece associated with the housing, a rotary valve acting as a throttling organ and being centrally arranged so as to be rotatable in the housing and closing the throttle aperture to a greater or a lesser extent, so that a fluid to be controlled passes through the inlet connection piece directly via the throttle opening. The rotary valve has a shaft with an axis, and also has a control edge and a rear edge which is opposite to the control edge. The control edge and the rear edge both extend obliquely relative to the axis of the shaft of the rotary valve.

  • Patent number: 5239961
    Abstract: A rotary idle-speed actuator for controlling a throttle cross-section in a line carrying combustion air for an internal combustion engine has an actuating motor with a stator and a rotor. The rotor is mounted on a shaft of a throttle member which more or less opens a control opening. The rotor has a cup-shaped form with a bottom and a cylinder-jacket-shaped wall. The stator has field windings and is arranged together with the field windings inside the rotor, and the stator is mounted only at its end which is opposite to the bottom of the rotor.

  • Patent number: 5234192
    Abstract: A rotational control device for the setting of angles in actuators, in particular of a restricting device used for determining the flow cross-section in a flow line for internal combustion engines, has an electrical setting motor with a two-pole status and a two-pole permanent magnet rotor. To obtain a robust setting motor, which is technically easy to manufacture in a compact construction, the stator poles are designed as claw poles and the stator winding is located as a toroidal coil in a ring space formed by the claw poles and a ring casing which is coaxial with these, for the magnetic return path. The stator winding is energized by a d.c. supply, with reversible current direction. The magnetic resistances in the magnetic return path and across the claw poles are calibrated such that in the event of a currentless stator winding, the permanent magnet rotor engages in the pole gaps between the claw poles.

  • Patent number: 5229671
    Abstract: In a rotary actuator (1) with rotary slide valve (3) for controlling a throttle cross-section, the sealing of the pneumatic (16) and of the electrical part (17) is to be improved. For this purpose, the shaft (11) is supported twofold, both on this side and on the other side of the rotary slide valve (3). Both roller bearings (13, 14) are located in a one-piece housing (12). As a result, the tolerance-related width of the air gap between rotary slide valve (3) and control opening (6) is reduced, on the one hand, and, on the other hand, an isolating seal between the parts (16) and (17) is formed by the bearing (13). The rotary actuator (1) is particularly suitable as idle-speed rotary actuator for internal combustion engines.

  • Patent number: 5087847
    Abstract: An electromagnetic rotating adjuster that has a servomotor with a can-shaped rotor, which is supported by means of a shaft via a first roller bearing and a second roller bearing, in which the disposition of the roller bearings in the one piece housing is inaccessible. For axial fixation of one second roller bearing, a spring washer is disposed in a second bearing opening and the second roller bearing is pressed against it, the outer race of the bearing having a detent groove on its circumference which groove is engaged by resilient detent tongues of a detent ring, supported in an annular groove of the housing. This assures secure fixation of the second roller bearing in the axial direction in a way that both suits the needs of large-scale mass production and is economical. The electromagnetic rotating adjuster may be used in control of the idling air in internal combustion engines. The resilient tongues and washer facilitate removal, as well as installation, of the rotor assembly.
