Abstract
An electromagnetic valve including a valve housing machine from free cutting steel wherein the housing and the valve's magnetic core are made from identical, high-alloyed chromium and molybdenum constituents, and wherein the valve housing is fabricated from a chromium-nickel alloy and a high-alloyed chromium-molybdenum compound.
Claims11
Electromagnetic valve, comprising:
- a housing having a sleeve-shaped portion,
- a valve closure member guided in the housing, said valve closure member effective for opening or closing a valve seat opening in the housing by means of a magnet armature which is operated by a valve coil and, wherein said valve closure member is movable along a magnetic core, wherein the housing or part of the housing is made by machining from free-cutting steel, wherein the housing and the magnetic core are made of a material of identical high-alloyed chromium and molybdenum constituents, and wherein the material of the sleeve-shaped housing portion selected from the group consisting of chromium-nickel alloy and a high-alloyed chromium-molybdenum compound further including a heat-shrinkable sleeve encompassing the sleeve-shaped housing portion.
Electromagnetic valve, comprising:
- a housing having a sleeve-shaped portion,
- a valve closure member guided in the housing, said valve closure member effective for opening or closing a valve seat opening in the housing by means of a magnet armature which is operated by a valve coil and, wherein said valve closure member is movable along a magnetic core, wherein the housing or part of the housing is made by machining from free-cutting steel, wherein the housing and the magnetic core are made of a material of identical high-alloyed chromium and molybdenum constituents, and wherein the material of the sleeve-shaped housing portion selected from the group consisting of chromium-nickel alloy and a high-alloyed chromium-molybdenum compound, further including a heat-shrinkable sleeve for covering at least one weld seam which connects the magnetic core to the housing portion.
Electromagnetic valve, comprising:
- a housing having a sleeve-shaped portion,
- a valve closure member guided in the housing and opening or closing a valve seat opening in the housing by means of a magnet armature which is operated by a valve coil and movable into abutment on a magnetic core, wherein the housing or part of the housing is made by machining from free-cutting steel, wherein the housing and the magnetic core are made of a material of identical high-alloyed chromium and molybdenum constituents, and wherein the material of the sleeve-shaped housing portion selected from the group consisting of chromium-nickel alloy and a high-alloyed chromium-molybdenum compound wherein the housing and the magnetic core are coated with at least one of a wax, lacquer or grease layer.
