Title
(EN) ELECTROMAGNETIC ACTUATOR UPPER SPRING ASSEMBLY
(FR) ENSEMBLE SUPERIEUR A RESSORT D'ACTIONNEUR ELECTROMAGNETIQUE
Abstract
(EN)
An electromagnetic actuator (10) includes housing structure (12), first and second electromagnets (14, 16) disposed in spaced relation in the housing structure, an armature (24) mounted for reciprocal movement between the electromagnets, and a spring assembly (11) operatively associated with the armature (24). The spring assembly includes a coil spring (30), a spring retainer (32) carrying the coil spring and being constructed and arranged to contact the armature (24), a spring adjusting member (38) engaged with a bore in the housing structure (12) and engaging the spring (30) so as to control compression of the spring associated with a set position of the armature (24) between the electromagnets. At least one cap screw (50) extends from a surface of the housing structue generally adjacent to the bore. A locking member (56) is engaged with the spring adjusting member (38) and with the cap screw (50). The cap screw (50) pushes against the locking member (56) to prevent movement of the spring adjusting member (38) to maintain the compression of the spring (30) associated with the set position of the armature (24).
(FR)
L'invention concerne un actionneur électromagnétique (10) comprenant une structure boîtier (12), un premier électroaimant et un second électroaimant (14, 16) placés à distance l'un de l'autre dans la structure boîtier, un induit (24) installé de façon à pouvoir effectuer un va-et-vient entre les électroaimants, ainsi qu'un ensemble à ressort (11) relié fonctionnellement à l'induit (24). L'ensemble à ressort comprend un ressort hélicoïdal (30), une coupelle de ressort (32) conçue et disposée de façon à être en contact avec l'induit (24) et sur laquelle s'appuie le ressort hélicoïdal, un élément de réglage du ressort (38) s'insérant dans un alésage de la structure boîtier (12) et s'appuyant sur le ressort (30) de telle façon que ledit élément commande la compression du ressort par rapport à une position donnée de l'induit (24) entre les électroaimants. Au moins une vis d'assemblage (50) sort d'une surface, généralement voisine dudit alésage, de la structure boîtier. Un élément de blocage (56) s'insère dans l'élément de réglage du ressort (38) et sur la vis d'assemblage (50). La vis d'assemblage (50) exerce une pression contre l'élément de blocage (56) pour éviter tout mouvement de l'élément de réglage du ressort (38) et maintenir la compression du ressort (30) relative à la position donnée de l'induit (24).
