Shut-off valve for controlled intake manifold of internal combustion engine, has spring element formed in one of crimps and supported on shaft surface, where geometry of crimps corresponds with shaft surface

摘要

#CMT# #/CMT# The valve has a shaft with an axially extending attachment region (12) comprising oppositely lying edge zones and a center zone, and a vane region (11) extending transverse to the attachment region. The attachment region in an installation position has a crimp (13) partly enclosing the shaft on a side and another crimp (14) partly enclosing the shaft on an opposite side. Geometry of the crimps corresponds with the shaft surface, a flap has a bearing, and a spring element (16) formed in one of the crimps is supported on the shaft surface. #CMT#USE : #/CMT# Shut-off valve for a controlled intake manifold of an internal combustion engine (all claimed) for regulating air supply according to an operating condition of the combustion engine. #CMT#ADVANTAGE : #/CMT# The spring element is formed in one of the crimps and is supported on the shaft surface, where the geometry of the crimps corresponds with the shaft surface, thus permitting supporting and attachment of the shut-off valve on the shaft with larger manufacturing tolerances, and manufacturing the valve in an economical manner. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a perspective view of a metal body of a shut-off valve. 11 : Vane region 12 : Attachment region 13, 14 : Crimps 16 : Spring element 17 : Projection.
