20080276613 | DISCRETE VARIABLE GEOMETRY COMPRESSOR - 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. | 11-13-2008 |
