Control device for axially blowable turbine, has monitoring device that compares force applied on coupling unit for adjusting guide vanes and/or position taken by coupling unit and outputs result for controlling exhaust gas turbine

摘要

#CMT# #/CMT# The device has a force determining device for direct and/or indirect determination of force applied on a coupling unit (8) for adjusting guide vanes (2) of an adjusting device i.e. servo motor (10). A position detecting device is provided for direct and/or indirect detection of position taken by the coupling unit, where the vanes are adjustable by an adjusting ring (6). A monitoring device compares the force applied on the coupling unit and/or the position taken by the coupling unit and outputs a result for controlling an exhaust gas turbine. #CMT# : #/CMT# An independent claim is also included for a method for functional safety of a control device. #CMT#USE : #/CMT# Control device for an axially blowable turbine of an exhaust gas turbo charger which is used for a stroke piston-internal combustion engine. #CMT#ADVANTAGE : #/CMT# The monitoring device compares the force applied on the coupling unit and/or the position taken by the coupling unit and outputs a result for controlling an exhaust gas turbine, thus increasing functional security of the control device. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a partial sectional view of a control device. 2 : Guide vanes 6 : Adjusting ring 7 : Spindle 8 : Coupling unit 10 : Servo motor.
