Lifting magnet arrangement for solenoid valve, has adjusting device adjusting prestress of spring device, where spring device acting on anchor piston axially against drive force is accommodated in central borehole

摘要

The arrangement (1) has a housing (2) with an anchor piston (4) longitudinally movably accommodated in the housing and has a central borehole (6). A coil (7) is arranged in an anchor chamber (3) and surrounds the anchor piston. A spring device (10) acts on the anchor piston axially against the drive force that is produced by the coil. An adjusting device adjusts the prestress of the spring device and the spring device is accommodated in the central borehole. An independent claim is also included for a solenoid valve.
