Abstract: The present disclosure provides a control valve including a camshaft and one or more poppet assemblies. In general, the one or more poppet assemblies can include a poppet carriage that is moveable by the camshaft between a first end position and a second end position, a poppet coupled to the poppet carriage, and a spring configured bias the poppet carriage radially away from the camshaft, toward the first end position, in a first radial direction relative to a camshaft axis. According to some aspects, the camshaft can include a cam lobe that engages the poppet carriage to move the poppet carriage from the first end position toward the second end position in a second radial direction that is opposite the first radial direction.

Abstract: A thermal management control valve includes a first housing defining a first fluid chamber, a second housing coupled to the first housing and defining a second fluid chamber, a rotary actuator having a drive shaft that defines a drive axis, a cam coupled to the drive shaft and having a cam slot, and a louver plate sealed between the first housing and the second housing and having a plurality of louver slots extending through the louver plate along a louver flow direction. The louver plate is coupled to the cam slot so that rotation of the cam selectively moves the louver plate along a radial direction relative to the drive axis. The radial direction is perpendicular to the louver flow direction.

Abstract: A disconnect system for selectively coupling or disconnecting a drive member and a driven member. The disconnect system includes a clutch ring rotationally coupled to a drive member, a solenoid actuator, and a shift fork coupled to the clutch ring and configured to be pivotally moved by the solenoid actuator. The shift fork configured to be selectively moved by the solenoid actuator to transition the clutch ring between an engaged position where the clutch ring is rotationally coupled to a driven member and a disengaged position where the clutch ring is disconnected from the driven member.

Abstract: The present disclosure provides systems and methods for an electromagnetic actuator having a unitary pole piece arranged within and coupled to a housing. The electromagnetic actuator can include the housing, the unitary pole piece, an armature received within the unitary pole piece, and an end cap. The unitary pole piece is structured to provide a reduction in air gaps within the electromagnetic actuator.

Abstract: An electromagnetic actuator having a unitary pole piece arranged within and coupled to a housing is provided. The housing is coupled to the unitary pole piece such that a load on the unitary pole piece is reduced during assembly and/or installation of the electromagnetic actuator. The unitary pole piece is structured to reduce leakage past an armature slidably received within the pole piece.

Abstract: An electromagnetic actuator includes an armature and an anti-saturation and damping shim. The armature is slidably actuatable and includes a central aperture providing fluid communication longitudinally along the armature. The anti-saturation and damping shim is configured to both dampen the actuation of the armature within an electromagnetic actuator and prevent the armature from making unwanted contact with other magnetic objects.

Abstract: Systems and method for a two-way clutch are provided. In some configurations, the two-way clutch includes a driven member having a first mating surface, a drive member having a second mating surface, and a locking mechanism arranged between the first mating surface and the second mating surface. The locking mechanism is operable to contact the first mating surface and the second mating surface, in response to an outside force applied to the drive member that loads the locking mechanism. The two-way clutch further includes an engaging member. The engaging member provides a predetermined interference on the locking mechanism to hold the locking mechanism off of at least one of the first mating surface and the second mating surface, when the locking mechanism is in an unloaded state.
