Abstract: A solenoid-actuated valve includes a solenoid portion extending along a longitudinal axis. The solenoid portion includes a solenoid housing defining a solenoid interior, a coil, and an armature, with the armature being moveable along the longitudinal axis in response to energization of the coil. The solenoid-actuated valve also includes a valve portion coupled to the solenoid portion. The valve portion includes a valve member moveable by the armature. The solenoid-actuated valve further includes a valve filter disposed in the solenoid interior and/or coupled to the solenoid housing and configured to separate the solenoid interior from a hydraulic circuit when the valve portion is coupled to a valve housing for allowing fluid to flow into and out of the solenoid interior upon actuation of the armature.

Abstract: An electrically-assisted turbocharger includes a shaft extending along an axis, a compressor wheel, a turbine wheel, a housing, and an electric machine. The electric machine includes a rotor rotatably coupled to the shaft and a stator lamination stack radially spaced from the rotor. The stator lamination stack has circumferentially spaced teeth defining gaps therebetween. The electric machine also includes a coil winding disposed in the gaps between the circumferentially spaced teeth and a guard plate disposed at one of the first and second stator ends. The guard plate extends radially away from the axis and includes a plurality of teeth guards extending radially, with each of the teeth guards aligned with one of the teeth of the stator lamination stack to electrically insulate the coil winding from the teeth of the stator lamination stack.

Abstract: A rotatable inner race is disclosed. The inner race may include a plurality of arcuate segments each having a first end with a first end geometry and a second end with a second end geometry. The first and second end geometries may be complimentary to each other to join adjacent arcuate segments at an interlocking joint. The rotatable inner race may further include a plurality of race engagement notches extending radially from an outer circumferential surface of each arcuate segment and the plurality of arcuate segments are joined together at the interlocking joints to form a race ring and the plurality of race engagement notches of each arcuate segment align with one another to define an array of race engagement notches around an outer circumference of the race ring.

Abstract: A linkage extends between an actuator and a valve in a turbocharger. The linkage comprises two spaced member bodies having central portions with opposing curved shapes that extend between ends translatable along and rotatable about spaced pivots. Translation of one member toward the other member compresses the central portions, increasing overall stiffness of the linkage, and translation of one member away from the other member creates a gap between the central portions, allowing independent translation of the ends along the spaced pivots to compensate for misalignment between the actuator and the valve caused by heat and vibration. Another linkage extending between an actuator and a valve in a turbocharger includes two planar spaced member bodies extending between ends translatable along and rotatable about spaced pivots. The two member bodies have different thicknesses.

The dual-mass flywheel extends along an axis and has an inner diameter portion disposed about and adjacent the axis and an outer diameter portion disposed about the axis such that the inner diameter portion is disposed between the outer diameter portion and the axis. The permanently engaged starter assembly includes a one-way clutch and a ring gear. The one-way clutch extends along the axis and includes an inner member disposed about the axis and an outer member disposed about the inner member. The ring gear is rotatably coupled to the one-way clutch and is adapted to be rotatably coupled to the outer diameter portion of the dual-mass flywheel through the one-way clutch.
