Magnet core of a magnet valve as well as a magnet valve

摘要

A magnet core of a magnet valve is guided in a core guiding tube of a solenoid so as to be axially shiftable, and cooperates at a first end face opposite a flow opening with a sealing system in such a manner that the flow opening is closed in a first end position and is open in a second end position. The magnet core is in flow communication with a valve space which is filled with a medium, in particular a medium of high viscosity. Around the circumference of the magnet core, a plurality of longitudinal grooves, extending in the direction of the longitudinal center line, extend toward the first end face, starting from a second end face opposite the first end face, the longitudinal grooves having at least a depth of 25% of the diameter of the magnet core. Further, a magnet valve comprising such a magnet core is described.

1. A magnet core of a magnet valve, said magnet core having a longitudinal center line, a first end face opposite a flow opening of the magnet valve and a second end face opposite the first end face, the magnet core being guided in a core guiding tube of a solenoid to be axially shiftable and cooperating at its first end face with a sealing system in such a manner that the flow opening is closed in a first end position and is open in a second end position, the magnet core being in flow communication with a valve space which is filled with a medium, wherein the magnet core has a plurality of longitudinal grooves arranged around its circumference, the grooves extending toward the first end face, starting from the second end face, each longitudinal groove having a depth of at least 25% of the diameter of the magnet core, wherein the magnet core comprises first and second longitudinal grooves, the first longitudinal grooves having a greater depth than the second ones.
