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.
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.
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 has a depth of at least 25% of the diameter of the magnet core, wherein the magnet core, adjacent to the first end face, comprises a surrounding constriction for receiving a spring, wherein two axially spaced transverse holes are arranged in the area of the constriction and protrude into the magnet core.
A magnet valve comprising a solenoid, a magnet core capable of being switched by the solenoid, and a flow opening which is surrounded by a valve seat and to be opened and closed by the movement of the magnet core, the magnet core having a longitudinal center line, a first end face opposite the 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 the 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 valve is designed such that fluid can flow via the longitudinal grooves to the first end face during the opening process of the valve, wherein the magnet core comprises a recess at the first end face, an axially biased sealing system being housed in said recess, and wherein a transverse hole in the magnet core opens into the recess at the rear side of a sealing element of the sealing system.
A magnet valve comprising a solenoid, a magnet core capable of being switched by the solenoid, and a flow opening which is surrounded by a valve seat and to be opened and closed by the movement of the magnet core, the magnet core having a longitudinal center line, a first end face opposite the 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 the 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 valve is designed such that fluid can flow via the longitudinal grooves to the first end face during the opening process of the valve, wherein the magnet core comprises a recess at the first end face, an axially biased sealing system being housed in said recess, and wherein a transverse hole opens into the recess at a side of a washer arranged within the recess which side is facing the sealing element.
