Furthermore, a shroud groove is partly defined by the diffuser plate (3).

Abstract: A compressor nozzle device comprises a set of adjustable vanes which is interposed between two opposite wall members (3, 5), and a unison ring (7) for actuating said vanes (1). The unison ring (7) is arranged at a side of one of said wall members (3) opposite to the other side thereof facing the vanes (1).

Abstract: A turbocharger includes a compressor housing (2) for accommodating a compressor wheel (5) drivable by an electric motor (21) and an electric motor (21) for driving a compressor wheel (5) accommodated in a compressor housing, the electric motor being supplied with electric power through at least one motor plug connector (12). The turbocharger further comprises a turbine housing (4), a center housing (3) for accommodating a shaft (6). The compressor wheel is driven by the turbine wheel (8) via the shaft (16) and can additionally be driven by the electric motor, where the compressor housing further includes at least one main power plug connector (16) disposed on an axial side of the compressor housing, facing the electric motor.

Abstract: The present invention provides an assembly comprising a compressor housing and EGR mixer, the assembly further comprising a ported shroud in the compressor housing and a noise suppressor in the EGR mixer.

Abstract: An exemplary compressor housing includes an axis to coincide with a rotational axis of a compressor wheel housed by the compressor housing, an inlet insert that includes an inlet port and a compressor wheel shroud portion that extends away from the inlet port to a ridge and a base component that defines, at least in part, a diffuser section and a scroll wherein the diffuser section extends radially outward to the scroll, wherein the ridge of the inlet insert defines, at least in part, an inlet to the diffuser section and wherein a joint exists between the inlet insert and the base component along a radius in the diffuser section. Various other exemplary technologies are also disclosed.

Abstract: An exemplary controller for a variable geometry compressor includes one or more inputs for receiving engine operating information and for receiving a signal representative of geometry of a variable geometry compressor and control logic to call for actuation of an actuator based at least in part on the engine operating information received by the one or more inputs and to call for actuation of the actuator based at least in part on the signal received by the one or more inputs whereby actuation of actuator causes a change in geometry of a variable geometry compressor. Various other exemplary technologies are also disclosed.

Abstract: A variable geometry compressor having a housing, a compressor wheel and a plurality of vanes positioned between an exducer of the compressor wheel and a housing volute. The vanes are adjustable through a range of positions, but a vane actuation system is configured to actuate the vanes through three discrete positions from among the range of positions. The actuation system has an actuator that includes an actuator housing containing a diaphragm that divides a housing chamber into two portions. Through the application of a vacuum to either chamber portion, the diaphragm drives a rod to actuate the vanes between two of the discrete vane positions, while a spring returns the vanes to the third position when no vacuum is applied. The actuator is controlled by an open-loop controller.
