Abstract: An electro-magnetic actuator includes a shaft having a first end portion and a second end portion and a nut having an inner peripheral surface and an outer peripheral surface. The inner peripheral surface of the nut is coupled with the first end portion of the shaft. A bearing is disposed around the second end portion of the shaft for rotatably supporting the shaft. An electrical coil is disposed around the shaft between the nut and the bearing for receiving electrical current and producing magnetic flux. A ferromagnetic can is disposed around the shaft having a peripheral surface extending between the shaft and the outer peripheral surface of the nut for establishing a path for magnetic flux flow there between. The peripheral surface of the can is interposed between the electrical coil and the bearing partitioning the electrical oil inside the can and the bearing outside the can.

Abstract: An encapsulated stator for use in solenoid-actuated liquid metering device has a bobbin assembly and a plunger guide which are substantially surrounded by a plastic overmold to hold the assembly together and provide a protective housing. Upper and lower ends of the plunger guide are not covered by the overmold, but rather are left exposed so that additional manufacturing and assembly steps may be performed upon the stator. The plunger guide is formed integrally with a support plate and two threaded body for receiving bolts to secure the stator in its operating position. A plastic cap with an integrally molded electrical connector housing for mating engagement with an electrical power supply is secured to the bobbin assembly and retains the core and plunger guide in proper positions relative to the bobbin prior to the assembly being encased in the overmold. A method of manufacturing the encapsulated stator is also disclosed.

Abstract: A holding device and a transmission shift interlock mechanism employing the holding device. The holding device is intended to immobilize a cable and includes a generally cylindrical electromagnet with a central passageway extending therethrough and a holding assembly comprised of a ferromagnetic body joined to a tubular non-magnetic stem. The ferromagnetic body and stem have a passageway therethrough and the stem passes through the central passageway of the electromagnet. The cable passes slidably through the stem and a stop collar is secured to the cable immediately forwardly of the stem for abutting coaction with the forward end of the stem.
