摘要:
A solenoid drive may include a ferromagnetic housing having a coil receiving chamber axially limited by opposing first and second face side walls, and a cylindrical coil arrangement having at least one electric coil, and being arranged in the coil receiving chamber and coaxially surrounding a cylindrical coil interior space. The solenoid drive may also include a ferromagnetic plunger stop having a central region projecting axially in the coil interior space, and a ferromagnetic plunger arranged at the housing opposing the plunger stop. The plunger may project axially into the coil interior space, and may be adjustable axially bi-directionally between an active position proximal to the central region and a passive position distal to the central region. The solenoid drive may further include a ferromagnetic bypass device arranged coaxially to the coil arrangement, radially within the at least one coil, and spaced apart axially from the face side walls.
