Abstract: A measuring instrument for contactless detection of an angle of rotation comprises a carrier plate (52) consisting of a magnetically soft material that serves as a rotor. The stator of the sensor comprises at least two parts, the ends (18 and 17) of which terminate in two planes. The measuring gap (M1) containing an element (20) that is sensitive to a magnetic field is located between the ends (18, 17). Due to the fact that the ends (17, 18) of the two stator parts (13, 14) terminate in different planes, the measuring element (20) can be situated in a very small measuring gap (M1) in which the magnetic flux of the magnet (5) can be concentrated.

Abstract: The fuel feed system has a feed unit (22), which has having an electric motor (32) as a drive mechanism and a pumping part (34) driven by the electric motor; the pumping part (34) is disposed offset from the electric motor (32), in the direction of the pivot axis (33) of the electric motor. A filter (24) is disposed beside the feed unit (22) and fuel pumped by the pumping part (34) flows through it. The feed unit (22) and the filter (24) are disposed in separate chambers (10, 20) of a common housing (16), between which chambers there is an overflow opening (60) for the fuel pumped by the pumping part (34). The housing (16) is tightly closed by means of a cap (26). The electric motor (32) and the pumping part (34) are inserted as separate structural units into a chamber (10) of the housing (16) and are braced against one another by at least one resilient element (58) in the direction of the pivot axis (33) of the electric motor (32).

Abstract: A measuring instrument for contactless detection of a path c is comprised of a two-part (14, 15) base plate (11), a side plate (16), and a movable part (12). The movable part (12) has a support plate (25) which is guided through a slot (26) in the side plate (16). At one end (27) of the support plate (25), there is a permanent magnet (28) which is embodied as smaller than the path (c). The magnet (28) can be embodied in one piece or in several pieces. Through the disposition of the magnet (28), it is possible to produce different sections, e.g. plateaus or sections deviating form the linear measurement line, in the measurement curve detected by the measuring instrument.

Abstract: In a travel measuring instrument (10), a magnet (11) which is polarized in the movement direction (R) is disposed against a flux conducting part (12). The flux conducting part (12) has a surface (13), which is inclined and is embodied as oval, which is disposed opposite a magnetic field sensitive element (15) with an air gap (L1). When there is movement, the air gap (L1) changes so that the magnetic field sensitive element (15) generates an output signal proportional or linear to the movement direction R of the component to be monitored.

Abstract: A measuring instrument for contactless detection of an angle of rotation is comprised of a supporting plate (14) made of soft magnetic material, which serves as a rotor. Two segments (16, 17, 16a) that are separated by a slot (21), a spacing gap (22), and a third gap (60) are disposed in a plane in relation to the supporting plate (14). The spacing gap (22) in this case is embodied in the segment (17) in the form of a recess. The gap (60), however, is disposed in the segment (16a), likewise in the form of a recess. The ratio of the size of the spacing gap (22) to the gap (60) can be modulated so that an offset shift of the characteristic curve is produced.

Abstract: A measuring instrument (10) for contactless ascertainment of a rotation angle is made up of a support plate (12) that is comprised of magnetically nonconductive material and serves as a rotor. A permanent magnet (15), which is embodied as planar, is disposed on the support plate (12) and its polarization direction is aligned diametrically to the axle (11). If the Hall element (20) is asymmetrically disposed, i.e. if the Hall element (20) describes an elliptical rotary motion in relation to the permanent magnet (15), then a steeply decreasing region and a flat region are produced in the curve of the output signal. No magnetic flux conducting parts are required in the measuring instrument (10). Furthermore, it is very small and relatively easy to incorporate into systems and devices.

Abstract: A measuring device for contactless detection of an angle of rotation is comprised of a supporting plate (14) made of soft magnetic material which is used as a rotor. In a plane in relation to the supporting plate (14), two segments (16, 17) are disposed, which are separated by means of a slot (21) and a spacer gap (22). The supporting plate (14) is fastened to an axle (11) whose extension (12) or the axle (11) itself is comprised of a magnetically conductive material. The extension (12) protrudes into one of the segments (16) of the stator. The axle (11), particularly its extension (12), the supporting element (14), and the segments (16, 17) control the magnetic flux of the permanent magnet (15) disposed on the supporting plate (14). Through the inclusion of the axle (11) into the magnetic flux, the measuring device is constructed in a relatively simple and space-saving manner.

Abstract: A measuring device for contactless detection of a rotational angle (&agr;) comprises a carrier plate (12), made of soft-magnetic material, which acts as a rotor. Two segments (15, 16) separated by a slit (17) are disposed in a plane parallel to the carrier plate (12). Disposed on one of the segments (16) is a short-circuit piece (20), and all these parts are of soft-magnetic material. The short-circuit piece (20) and the segments (15, 16) serve to guide the magnetic flux that is generated by a permanent magnet (13) disposed on the carrier plate (12). Since the short-circuit piece (20) protrudes past the carrier plate (12), or in a further feature the carrier plate (12) protrudes past the short-circuit piece (20), insensitivity to axial or radial play is possible. Furthermore, the measuring device is relatively simple and space-saving in design.

Abstract: The measuring device for contactless determination of a rotation angle includes a rotatable permanent magnet (22) arranged in a stator (10) made of magnetically conductive material and including two stator segments (13,14) and a surrounding cup-shaped housing part (11). One stator segment (14) is mounted directly on the bottom (15) of the housing part (11) so that a magnetically conductive connection exists. A layer (18) of magnetically nonconductive material is present between the other stator segment (13) and the bottom (15) so that no magnetic flux is possible there. The rotatable permanent magnet (22) is arranged so that it is movable in an air gap between the two stator segments (13,14) and the housing part (11) with the direction of magnetic polarization oriented radially, i.e. toward the stator segments (13,14) or in the opposite direction. The measuring element (20) is arranged in the slot (12) between the two stator segments (13,14).

Abstract: A temperature probe in which mechanical oscillatory excitation that can lead to fracture of the connecting lines is prevented and the response time of the temperature probe to temperature changes is shortened. According to the invention, a resistance element is disposed in a flow window of the temperature probe which is formed by a protective bracket and which projects into a flow line. At least one of the connecting lines that is connected with the resistance element exhibits at least one bent point, which is held in at least one retaining opening formed in the protective bracket, whereby the connecting lines are stabilized. The temperature probe may be used for measuring the temperature of intake air in an intake pipe of a mixture-compressing, external-ignition internal combustion engine.

Abstract: A measuring instrument for contactless determination of an angle of rotation of an adjusting shaft. To avert transmitting a tumbling motion from the adjusting shaft to the measuring instrument, a coupling body is provided, which with engagement protrusions, engages engagement grooves of a driver body with play. The driver body actuating the measuring ring is as a result decoupled from tumbling motion effected by the adjusting shaft. The measuring instrument is especially suitable for contactless determination of the angle of rotation of a throttle device in an internal combustion engine.
