Guide vane adjusting device for loading device i.e. turbocharger, has control slot with curved section that is designed such that slot supports force transferred from guide vane to swivel arm

摘要

The device has multiple guide vanes (30) tiltably arranged in a guide vane carrier (32), where each van has a swivel arm (33) that intervenes with a projection. A control slot of an adjusting element (34) is rotatable around a rotation axis (9). The control slot has a curved section that is curved relative to a radial direction running perpendicular to the rotation axis by the assigned projection such that slot supports force transferred from the guide vane to the swivel arm. The projection is perpendicular to the control slot.
