摘要： A rotary magnetic position indicator for displaying 10 discrete indicia in response to a one or two of five code or a one of five reverse polarity code. A stator core has a yoke with 10 equally spaced, inwardly extending teeth having inner ends defining a bore. A permanent magnet rotor member is rotatably mounted in the bore and has oppositely polarized diametrically opposite ends each spanning the inner ends of three stator teeth and forming air gaps therewith. Five identical field windings are provided each having first and second ends and each comprising first and second coils on the yoke, there being one coil between each different pair of teeth and the two coils of each different winding having a different group of three teeth therebetween. The first end of each different winding is connected to a different external terminal and the seconds ends of all the windings are connected to a common terminal. The windings are arranged so that upon connection of each different one of the external terminals and the common terminal to a source of direct current, a different group of three adjacent teeth are excited with one polarity, and so that upon connection of the external terminals respectively connected to each different pair of adjacent windings and the common terminal to the source, a different group of five adjacent teeth are excited with one polarity with the middle one of the group of five teeth having a higher magnetic flux density therein than the remaining projections of the group.

摘要： A rotor member for a rotary magnetic position indicator incorporating two abutting permanent magnets. The first permanent magnet is cylindrical and has oppositely polarized areas at the respective extremities of a diameter. The second permanent magnet has at least two polar projections joined by cylindrical surface portions, the projections being oppositely polarized. The magnets are oriented with the polarized areas and projections of the same polarity being generally axially aligned.

摘要： A fuel injection valve having a hollow plastic nozzle with a discharge orifice at its front end, and a plastic bobbin with a hollow barrel and spaced flanges, the nozzle and barrel being in spaced alignment, and a coil surrounding the barrel between the flanges. A valve plunger in the nozzle is movable between closed and opened positions and has a front end which closes the orifice in the closed position, the plunger forming a first fluid passage communicating with the orifice. A magnetic casing surrounds a part of the nozzle and the bobbin and coil, and holds the nozzle and bobbin in assembled relation, the casing having a portion bridging the space between the nozzle and barrel. An armature is attached to the rear end of the plunger and has a portion extending into the space between the nozzle and bobbin and defining a first, fixed airgap with the bridging portion of the casing, the armature also forming a second fluid passage communicating with the first passage. A magnetic core is positioned in the barrel and forms a second airgap with the armature in its closed position, the core, casing and armature forming a magnetic circuit for the coil. The core forms a third fluid passage communicating with the second passage, and a spring normally biases the armature and plunger to the closed position. The core is secured to the casing, and the casing includes an inlet conduit communicating with the third passage.
