Electromagnetic actuator for controlling leak volume in movement dampening arrangement, has springs fixed by their centre respectively at ends of pin and by their periphery respectively at support and cover

摘要

The actuator (50) has a fixed assembly (10) with a winding (2) enclosed between a winding support (1) and a cover. A movable assembly (20) has a core (5) connected in translation to a pin (4). An air-gap (6) is assured between the support and the core. The movable assembly is suspended and centered without contact with respect to fixed assembly by two disk shaped spider springs (7, 8) axially disposed from the movable assembly. The springs are fixed by their centre respectively at ends (41, 42) of the pin and by their periphery respectively at the support and the cover.
