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.

摘要： A starter for an internal combustion engine may include a support, an electric motor for driving a pinion in rotation, and a solenoid drive configured to axially adjust the pinion between an active position for driving a gearwheel of an internal combustion engine, and an axially offset passive position. The solenoid drive may include a ferromagnetic solenoid housing fastened to the support, a ferromagnetic plunger stop arranged one of in and at the solenoid housing, a ferromagnetic plunger axially adjustable relative to the plunger stop extending axially through a passage opening of a face side wall of the solenoid housing, and a cylindrical coil arrangement arranged in the solenoid housing surrounding a cylindrical coil interior in a circumferential direction. The plunger stop may include a cylindrical section projecting axially into the coil interior. The cylindrical section may have a face end facing towards the face side wall.

摘要： A starter for an internal combustion engine may include a support, an electric motor for driving a pinion in rotation, and a solenoid drive configured to axial adjust the pinion between an active position and a passive position. The solenoid drive may include a ferromagnetic plunger stop, a plunger axially adjustable, and a cylindrical coil arrangement surrounding a cylindrical coil interior. The plunger stop may include a cylindrical section projecting into the coil interior. The plunger may be arranged axially opposite the cylindrical section and, when the pinion is in the active position, protruding axially into the coil interior. When the pinion is in the passive position, a face-side plunger end may be arranged axially in a proximal end portion. The cylindrical section may extend into the coil interior such that a face end is closer to the proximal end portion than to a distal end portion.

The plunger may project axially into the coil interior space and may be adjustable axially bi-directionally relative to the housing between active and distal positions, which are proximal and distal, respectively, with respect to the central region. The bypass device may be spaced apart axially from the face side walls. In the passive position, the plunger may project axially into the bypass device such that an axial overlap between the plunger and the bypass device may be defined.
