ELECTRO-MAGNETIC BLOCK AND DEVICE FOR ELECTROMAGNETIC SELECTION OF THE MOVEMENT OF RAIN BLADES AND OTHER MECHANICAL MECHANICAL FORMATION OF THE CROWD

摘要

This electromagnet unit comprises, for each blade, an electromagnet (4) which is associated with a selector (9) equipped with a movable armature (13). A substantially planar face (13A) of the movable armature (13) is able to come against an abutment face (4A) of the electromagnet, this face (4A) comprising a stop plate (8) at the level of which open first (61) and second (62) poles. According to the invention, the abutment plate (8) has a portion (82) projecting from a main portion (81) of the plate and to the poles (61, 62). The protruding portion (82) is arranged in the vicinity of a pole (62), so as to bear one end (132) of the movable armature (13) corresponding to this pole (62), while the portion main (81) receives an opposite end (131) of the movable armature (13) corresponding to the other pole (61).
