摘要： A push-pull solenoid is provided with a cylindrical guide member that is fixed to a case. A circular outer peripheral surface of a plunger is in contact with a friction guide surface formed on a circular inner peripheral surface of the guide member, and slides along the friction guide surface. Frictional force due to contact with the friction guide surface is always acting on the plunger, so it is possible to suppress impact-like contact of the plunger with an object to be manipulated during suctioning, and vibration and noise caused thereby. Moreover, over-recovery and falling-out of the plunger after suction is released can also be prevented.

摘要： 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.

摘要： An example variable reluctance device includes a load structure connected to an armature through a connecting arm. The armature is positioned between two oppositely oriented core structures. A structural frame secures the core structures in a fixed position, forming gap regions between the core structures and the armature, forming a magnetic circuit. The armature is resiliently centered between the core structures by a spring, such that the gaps and are approximately equal in width when the armature is at rest. The device further includes a magnetic substance within the gaps that is compressed or stretched to allow movement of the armature.
