Pivotable control valve for controllable opening and closing of double-flow bypass duct of turbine housing of supercharger of combustion engine, has flow guidance device arranged in bypass ducts and/or flow channel

摘要

#CMT# #/CMT# The control valve (1) has a flow guidance device (6) arranged in bypass ducts (2, 2') and/or a flow channel for influencing gas flow (7) of the bypass ducts and/or gas flow of the flow channel. Force is generated by the gas flow of the bypass ducts and eccentrically introduced into the control valve when the bypass ducts are opened by the control valve such that a bearing bolt (3) arranged at the control valve lies in a bearing (15) arranged in an actuator (4) due to torque introduced to the bearing bolt. #CMT#USE : #/CMT# Pivotable control valve for controllable opening and closing of a double-flow bypass duct of a turbine housing of a supercharger of a combustion engine. #CMT#ADVANTAGE : #/CMT# The valve ensures safe closing and opening of a double-flow bypass duct. The force generated by the gas flow of the bypass ducts is eccentrically introduced into the control valve, so that the control valve is heavily loaded on one side, thus obviating flutter and associated noise developments during opening the control valve, and enabling retention of axial and radial clearance in a bearing of the control valve, and hence achieving gas-tight closure of the bypass ducts. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a sectional view of a pivotable control valve. 1 : Pivotable control valve 2, 2' : Bypass ducts 3 : Bearing bolt 4 : Actuator 6 : Flow guidance device 7 : Gas flow of bypass ducts 15 : Bearing.
