Abstract: Pressure piston actuators and systems for control of wastegate in a turbocharger pressure that include the pressure piston actuators are disclosed. The pressure piston actuator includes a housing defining a chamber and a pathway leading to the chamber, a piston disposed within the chamber, a rod connected to the piston by a ball-and-socket joint, and a spring disposed in the chamber to bias the piston, and hence the rod, into a retracted position. Then, when fluid is introduced into the chamber, the fluid applies pressure to the piston. Once the pressure overcomes the bias of the spring, the piston, and hence the rod, moves into an extended position. For the system, the pressure piston actuator has the connector on the end of the rod opposite the ball-and-socket joint connected to the valve portion of a wastegate of a turbocharger.

Abstract: Turbochargers are disclosed that have a braking system to brake the rotation of an electrically conductive compressor wheel within the turbocharger. The brake system includes the electrically conductive compressor wheel, which is connected to a turbine by a common shaft, one or more electromagnets positioned proximate to the compressor wheel, and a control circuit electrically coupled to the one or more electromagnets to turn the one or more electromagnets on or off to provide braking action to the compressor wheel. Systems including such a turbocharger and methods utilizing such turbochargers are also included herein.

Abstract: An assembly comprising a clipping bracket mounting a first component to a second component, the second component having an array of fixings, the bracket comprises a first leg attached at one end to one of the fixings; the bracket further comprises a clipping member extending from the second end and partly defined by two fingers engaging around, but not under, either side of an adjacent fixing.
