20110232280 | TURBOCHARGER DIVERTER VALVE - A piston actuated diverter valve is employed to recirculate air through a turbocharger compressor when the device is not activated in an engine. An example diverter valve includes a housing forming a cylinder. A piston is arranged within the cylinder and an aperture passes from an exterior of the housing into the cylinder. A conduit is connected to the cylinder such that a pressurized fluid in the conduit acts to move the piston within the cylinder to cover and/or uncover the aperture. | 09-29-2011 |
