Abstract: An air bypass valve (10) includes a solenoid assembly (30) including a magnetic housing (32), a coil bobbin (34) in the magnetic housing, a coil (36) disposed about the coil bobbin, and a magnetic flux ring (38) coupled with the magnetic housing. An armature and seal assembly (12) includes an armature structure (14, 16) that can move with respect to the solenoid assembly from a closed position to an open position in response to a magnetic field generated by the coil. Seal structure (22) is coupled with armature structure so that the seal structure can pivot with respect to the armature structure. The seal structure has a sealing edge (28) to seal with a manifold component when the armature structure is in the closed position thereof. A spring (44) biases the armature structure to the closed position and a main housing covers (46) the magnetic housing.

Abstract: A solenoid device includes a solenoid assembly (30) including a stator (42, 32, 38), a coil (36) for generating a magnetic field, and first retention structure (64). Armature and seal assembly includes armature structure (14, 16) that moves with respect to the solenoid assembly from a closed position to an open position in response to the magnetic field generated by the coil, seal structure (22) that is coupled with a proximal end of the armature structure and has a sealing edge (28) to seal with a component when the armature structure is in the closed position thereof, and second retention structure (68). A spring (44) biases the armature structure to the closed position. The first and second retention structures engage and retain the armature and seal assembly with respect to the stafor assembly prior to installation of the device.

Abstract: An armature-stator structure (45) includes a stator (56) having a magnetic housing (57) of generally U-shaped cross-section. The housing includes an open end (58) in communication with an interior portion (60). A coil (94) is associated with the stator and to be energized to generate a magnetic field. An armature (46) has a generally ring-shaped base (48) and a generally rod-shaped stem portion (50) extending transversely from the base such that the base and stem portion define a generally T-shaped cross-section. The base is able to be received in the opened end of the housing with the stem portion extending into the interior portion. The armature moves with respect to the stator from a first position to a second position in response to the generated magnetic field. The stator and armature are configured such that a force on the armature decreases as a portion of the armature moves further into the interior portion of the body of the stator, towards the second position.

Abstract: Power converter system topologies comprise a DC/DC converter. The DC/DC converter includes a transformer coupling a high side to a low side. The high side may include an inverter bridge in the form of an inverter module and an inductor. The low side may include a rectifier in the form of a rectifier module and a pair of inductors. The transformer may take the form of a planar transformer.
