A common transformer used with an electric vehicle that includes a transformer core configured to receive electrical windings from a plurality of electrical circuits; an alternating current (AC) synchronous rectification (SR) circuit electrically connected to the transformer core via an AC winding; a high-voltage SR DC circuit electrically connected to the transformer core via a high-voltage DC winding; and a low-voltage DC SR circuit electrically connected to the transformer core via a low-voltage DC winding.

Three-way transformer for power conversion in electric vehicles

A variable camshaft timing (VCT) assembly for controlling angular positions of concentric camshafts. The VCT assembly includes an independent VCT device and a dependent VCT device. The independent VCT device is hydraulically- or electrically-actuated. The independent VCT device is coupled with a first concentric camshaft and has a first component that rotates during phasing movements. The first component has a first set of slots therein. The dependent VCT device is coupled with a second concentric camshaft. The dependent VCT device has a second component that lacks rotation during phasing movements, and has multiple phase lugs. The second component has a second set of slots therein. The phase lugs are received in the first set of slots and are received in the second set of slots.

Variable camshaft timing assembly

A linkage mechanism for a valve assembly includes one of a slot and an engagement component operably coupled to at least one drive component and located eccentrically from a rotational axis of the at least one drive component, a link operably coupled to one end of a valve stem of a valve member and being moveable with the valve stem, the link having another one of a slot and an engagement component, and a rotatable lever coupled to at least one housing, the lever including one of a first slot and a first engagement component operably engaged with the one of the slot and the engagement component of the at least one drive component and one of a second slot and a second engagement component operably engaged with the one of the slot and the engagement component of the link, wherein rotation of the at least one drive component causes the lever to rotate to convert a rotational movement of the at least one drive component to a linear movement of the link such that the link, the valve stem, and the valve member are moved axially in a direction along a longitudinal axis of the valve stem.

Split linkage mechanism for valve assembly

A valve assembly includes a valve housing defining a bore with a first axis extending along a length of the bore, and a valve shaft partially disposed within the bore along a second axis that is perpendicular to the first axis. The valve assembly additionally includes a valve plate coupled to the valve shaft and disposed within the bore, and a restricting device including a stop member and an engagement member. The stop member extends from the valve housing and presents a stop surface. The engagement member extends from the valve shaft and presents an engagement surface. At least one of the stop surface and the engagement surface is non-parallel with the second axis. The at least one non-parallel surface engages the other of the stop member and the engagement member and biases the valve shaft axially along the second axis.

Valve assembly and valve system including same

An actuator assembly moves an output shaft. The actuator assembly includes a housing having at least first, second, and third sections at least partially defining first and second cavities, with the third section between the first and second sections. A motor assembly has a rotatable drive shaft and is coupled to the third section. The motor assembly is at least partially disposed in the first cavity and the drive shaft is at least partially disposed in the second cavity. At least one drive gear is within the second cavity and is fixed to the drive shaft. At least one driven gear is within the second cavity and is coupled with the output shaft. The at least one driven gear is coupled to the third section of the housing and is rotatably coupled with the at least one drive gear to transmit rotation from the drive shaft to the output shaft.

A number of variations may include a product, which may include an actuator including a rotatory portion for moving a valve from a first position to a second position and a biasing spring for retuning the valve to the first position.

Actuator with valve return

One embodiment includes an air pump assembly () with an impeller (), a housing (), and a diverter (). The impeller () has an axis of rotation (R). The housing () surrounds the impeller () and has an inlet passage () with a longitudinal axis (L) arranged generally orthogonal to the axis of rotation (R) of the impeller (). The diverter () helps reduce turbulent fluid-flow in the inlet passage ().

Inlet design for a pump assembly

A method of controlling a device having restricted movement. A controller is provided for controlling the operation of the device using a control algorithm. A normal operation control method is programmed onto the controller and is selectively activated by the controller to generate a normal control signal. A forcing control method is also programmed into the controller and selectively activates a forcing control signal. The normal operation control signal provides regular operation of the device, while the forcing control signal causes the device to operate in a manner that will correct the operation of the device when a restricted motion of the device is detected.

Control algorithm for freeing an EGR valve from contamination adhesion

One embodiment includes an air pump assembly () with an impeller (), a housing (), and a diverter (). The housing () surrounds the impeller () and has an inlet passage () with a longitudinal axis (L) arranged generally non-orthogonally with respect to an axis of rotation of the impeller (). The diverter () helps reduce turbulent flow in the inlet passage ().

The present invention is directed to an actuator assembly () having an actuator device () operably associated with a housing (), one or more rotating gear members () operably associated with the actuator device (), a bearing member () operably associated with the one or more rotating gear members (), and a cam () operably associated with the one or more rotating gear members (), for translating rotary motion of the gear members () to axial motion. When the actuatordevice () is actuated, the one or more rotating gear members () rotate, causing the bearing member () to move on the cam ().

Actuator assembly using a cam slot bearing drive mechanism

A method for controlling an actuator, such as the type used to drive valves, vanes, and other variable position devices. In one exemplary embodiment, a method may improve the accuracy of actuator feedback by periodically or dynamically resetting the position of a lower hard stop, which can then be used as a future point of reference.

Method for controlling an actuator

A method including obtaining information representative of the amount of oxides of nitrogen and the amount of particulate matter being produced by a combustion engine, and adjusting the amount of oxides of nitrogen and the amount of particulate matter being produced by the combustion engine by controlling the amount of combustion engine exhaust gas re-circulating through an EGR cooler and through an EGR cooler bypass line using the information.

An actuator assembly having a housing, at least one rotating gear member including a cam, and an actuator device operably connected to the rotating gear member, operably contained in the housing, for rotating the gear member. Also included is a bearing member operably associated with the cam such that when the actuator device is actuated for rotation of the gear member, the bearing member moves on the cam for providing relative motion between the bearing member and the rotating gear member. The actuator device is selected from a torque generating device or a device having linear movement.
