Leaktight magnetic drive device without wall penetration and ultrasound probe including application thereof

摘要

The invention relates to a magnetic drive device making it possible to drive a member placed on one side of a non-magnetic wall (18) from a rotary driving shaft (10) placed on the other side of the wall. The driven member is mounted so that it can tilt about an axis of oscillation (16) orthogonal to the axis of rotation (12) of the driving shaft (10) and carries a magnet (28) with axial magnetisation, the outer surface of which has a substantially circle-shaped cross-section centred on the axis of oscillation, in the plane containing the axis of oscillation and the axis of rotation (12) of the driving shaft (10). The driving shaft (10) bears a magnet (20) with axial magnetisation, away from the axis. IMAGE
