Abstract

Ce solénoide (10) comprend une armature mobile (11) qui peut se déplacer sur une certaine longueur (13) de course par rapport à un aimant (15). L'armature comporte un noyau (17) constitué d'un matériau magnétique et ayant une première longueur. L'aimant peut etre alimenté électriquement pour fournir un flux magnétique et il présente un trajet de flux ayant une deuxième longueur qui est supérieure à la première longueur ou longueur du noyau. De ce fait, l'aimant exerce sur le noyau une force d'attraction dont l'intensité augmente linéairement sur toute la longueur de la course.This solenoid (10) comprises a movable armature (11) which can move over a certain length (13) of travel relative to a magnet (15). The frame comprises a core (17) made of a magnetic material and having a first length. The magnet can be electrically powered to provide magnetic flux and has a flux path having a second length which is greater than the first length or length of the core. As a result, the magnet exerts an attractive force on the core, the intensity of which increases linearly over the entire length of the stroke.
