Abstract: Disclosed is a exhaust gas recirculation valve including a motor turning a shaft, a cam disposed on the shaft, the cam having a profile, and a valve assembly including a seat and a pintle. The pintle is disposed for reciprocal movement with respect to the valve for permitting and prohibiting delivery of exhaust gas through the valve assembly. The pintle is also in contact with the profile of the cam such that constant angular motion of the torque output shaft is converted to non-linear motion of the pintle.

Abstract: A stator assembly (16) for a brush-type permanent magnet DC motor includes a stator body (17) having a central axis A and an annular inner wall (20) disposed about the central axis. The inner wall has at least one raised portion (21) and at least one recess (22) adjacent to the at least one raised portion. The raised portion defines a flux recovery feature. At least one permanent magnet (18) is disposed within the recess (22) such that an inside radius IRM of the magnet is substantially the same as, and concentric with, an inside radius IRF of the raised portion as measured from the central axis, with the flux recovery feature (21) and magnet (18) defining a magnetic circuit. In section, the at least one raised portion is joined with a surface defining the at least one recess by a generally S-shaped structure thereby defining a curved transition there-between. Thus, in a motor having N poles, only N/2 magnets are required.

Abstract: An active noise cancellation system (20) for use with an assembly (22) includes adjusting the phase of a reference signal an amount that corresponds to a change in phase of the noise (26) within the system. A non-acoustic sensor (44) provides a signal regarding a position or frequency of a source of noise (28) (i.e. RPM's of a vehicle engine). Control electronics (32) provide a reference signal to the system noise canceling actuator (30) (i.e., a speaker) that includes the phase adjustment responsive to the sensor signal. In one example, the reference signal is delayed an amount of time corresponding to the phase change in the noise (26) as it travels through the system (22). In another example, the phase angle is adjusted.

Abstract: A damping structure reduces chatter caused by shaft (10) vibrations within a bearing bore in a manifold. The damping structure is incorporated into the shaft (10) and has a resilient member (18) and a contact member (20) inside a shaft bore (16) machined into the shaft (10). The contact member (20) presses against the inside surface of the bearing bore (16), placing a load on the shaft (10) that dampens chatter-inducing vibrations.

Abstract: A flow tube for an induction system with a turbo charger defines a longitudinal flow path and includes a noise attenuation plate positioned within the flow tube. A plurality of ribs formed on an internal surface of the tube. The ribs are spaced apart from one another and are tuned to a desired frequency. The noise attenuation plate includes a plurality of holes having varying diameter and depths. When acoustic energy created by the turbo charger encounters the noise attenuation plate and the ribs, the change in impedance results in acoustic reflections back toward the turbo charger. Thus the noise attenuation plate cooperates with the ribs to serve as a low pass filter that attenuates high frequencies while allowing lower frequencies through.

Abstract: An automotive emission control valve, such as an EGR valve, has a solenoid for operating a valve element. The solenoid stator has an annular air gap disposed within an electromagnet coil. An annular wall of an armature is disposed in the air gap. The armature is displaced by magnetic flux in the air gap. The air gap is cooperatively defined by juxtaposed walls of the stator that are spaced radially a distance greater than radial thickness of the annular wall of the armature. The annular wall of the armature is disposed radially intermediate the stator walls and spaced from each stator wall. The radially inner stator wall is tapered. Lost-motion is present between the armature and valve element so that initial armature displacement is not transmitted to the valve element. Dimensions of the stator walls and armature at the air gap may be selected to improve linearity of operaton.
