摘要

#CMT# #/CMT# The valve device (14) has a plate-shaped valve element (20), a mandrel (21) with a mandrel stem projecting from the valve element and a mandrel head (23), which is broadened at its free end corresponding to the mandrel stem. A spindle (25) is provided for adjusting the valve element around a spindle axis (26). The mandrel is rotatably connected with a washer element (29) corresponding to the mandrel longitudinal axis (24). The washer element is rotatably supported on a spindle arm (27) corresponding to the mandrel longitudinal axis. #CMT#USE : #/CMT# Valve device for a wastegate valve of a turbine, particularly an exhaust gas turbocharger (all claimed) of an internal combustion engine of a motor vehicle. #CMT#ADVANTAGE : #/CMT# The mandrel is rotatably connected with a washer element corresponding to the mandrel longitudinal axis, where the washer element is rotatably supported on a spindle arm corresponding to the mandrel longitudinal axis, and thus enables a simple structure and an economical manufacturing of the valve device, and also enables torque-proof coupling between the mandrel and washer element by increasing friction at the mandrel head and the washer element, and ensures an easy and accurate assembly of the valve device. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a perspective view of a valve device. 14 : Valve device 20 : Valve element 21 : Mandrel 23 : Mandrel head 24 : Mandrel longitudinal axis 25 : Spindle 26 : Spindle axis 27 : Spindle arm 29 : Washer element.
