电磁致动器和用于制造这样的致动器的方法
摘要：
本发明涉及一种电磁致动器(10)，其包括铁磁壳体(12)、两个电磁线圈(14、16)、铁磁单元(24)、铁磁柱塞(22)，所述铁磁壳体在纵向方向(X)上延伸并在垂直于纵向方向(X)的垂直方向(Z)上具有高度(H1)，所述两个电磁线圈定位在壳体(12)内，并且各自包括绕纵向方向(X)的至少一个绕组(36、38)，所述铁磁单元布置在线圈(14、16)之间，所述铁磁柱塞承受由线圈(14、16)产生的磁场，所述柱塞(22)在纵向方向(X)上是可移动的，并能够被固定在取决于所述线圈(14、16)所产生的场的三个不同纵向位置上。铁磁单元(24)刚性地连接到壳体(12)，并在垂直方向(Z)上具有大于壳体(12)的高度(H1)的六分之一的尺寸(H2)，所述铁磁单元(24)还相对于中平面(P)定位在小于所述两个线圈(14、16)之间沿纵向方向(X)的间隙(E)的四分之一的距离处，所述中平面垂直于所述纵向方向，并且位于所述两个线圈(14、16)之间的中间处。
摘要（英）：

An electromagnetic actuator, including: a ferromagnetic housing extending in a longitudinal direction with a height in a vertical direction perpendicular to the longitudinal direction; two coils arranged inside the housing, each including at least one winding around the longitudinal direction; a ferromagnetic member arranged between the coils; and a ferromagnetic plunger subjected to a magnetic field generated by the coils, the plunger movable in the longitudinal direction and to be immobilized in three different longitudinal positions depending on the field generated by the coils. The ferromagnetic member is rigidly connected to the housing and has, in the vertical direction, a size greater than one sixth of the height of the housing, and located at a distance smaller than one fourth of a gap in the longitudinal direction between the two coils, relative to a median plane perpendicular to the longitudinal direction and located at the midpoint between the two coils.
