摘要： An electromagnetic actuator including a soft-ferromagnetic yoke is described. The electromagnetic actuator includes an at least substantially cylindrical circumferential wall covered at a first end with a base and at a second end with a top, the circumferential wall defining an axis in a direction from the base end to the top. An intermediate yoke section holds a permanent magnet fixed that leaves an inner space housing an axially movable core element being flexibly restrained with at least one resilient element. One of a base yoke section and/or a top yoke section houses an electromagnetic coil.

摘要： The invention relates to a highly dynamic electromagnetic drive in the manner of a Thomson coil with soft-magnetic frame, comprising a first excitation coil (30) whose winding height is greater than its length, which hence is flat; a soft-magnetic frame (10) in which the first excitation coil (30) is arranged and against which it abuts, and which in in the manner of a pot magnet constitutes an open magnetic circuit which includes an outer region (11), a bottom (12) and an inner region (13), and which is open on its end face, wherein the first excitation coil at least partly encloses the inner part (13) of the frame; a short circuit armature (40) preferably formed hollow cylindrical at least on its side facing the first excitation coil (30), which is movably mounted along an axis and which in its stroke starting position dips into the end-face opening of the frame (10) and thereby at least partly encloses the inner part of the frame (13), wherein the frame (10) entirely or predominantly is formed of a soft-magnetic composite material or one or more sheet stacks, which has a saturation flux density of at least 1.5 T and an effective specific electrical conductivity of not more than 106 S/m, and the first excitation coil (30) and/or the frame (10) include at least one means for strain relief, in particular in the form of an enclosure in order to at least partly absorb at least the radial forces occurring on the first excitation coil (30) during an actuating operation vertically to the direction of movement, and wherein the Lorentz force acting on the short circuit armature is used to perform work.

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： A solenoid valve includes a valve portion and a solenoid portion. The valve portion has a sleeve and a valve body inserted into the sleeve. The solenoid portion includes a stator core having a magnetic attraction core, a sliding core, a magnetic flux passage suppressing portion that suppresses the passage of magnetic flux between the sliding core and the magnetic attraction core, a magnetic yoke, a coil portion, a plunger, and a magnetic tubular base portion. The base portion is fastened to a first outer peripheral surface of an end on the solenoid portion side in the axial direction of the sleeve, is arranged outside a radial direction of a second outer peripheral surface of the end on the valve portion side in the axial direction of the magnetic attraction core, and comes into contact with the yoke inside the yoke.
