Abstract

The invention relates to a solenoid valve that is to be mounted leaktight and in a simple manner. Provided according to the invention is a first housing part with a tool engagement portion for screwing of a second housing part into an inner thread of a receptacle. The two housing parts are joined immovably to each other. The first housing part has a tensile strength that is greater than a tensile strength of second housing part.

Claims (27)

1. A solenoid valve, comprising:

a first and a second housing part,

a coil,

an armature,

a plunger mounted in a linearly movable manner for opening and closing the solenoid valve, the plunger being acted on by the armature,

the first housing part having a tool engagement portion for screwing of the second housing part into an inner thread of a receptacle,

the first and second housing parts being joined to each other immovably, and

the second housing part having a tensile strength that is greater than a tensile strength of the first housing part.

2. A solenoid valve according to claim 1 , wherein the tool engagement portion lies in a magnetic flux, a wall thickness of the first housing part in a region of the tool engagement portion being greater than the wall thickness outside of the magnetic flux.

3. A solenoid valve according to claim 1 , wherein the plunger is mounted inside of a bushing, which bushing is constructed with a shoulder in such a way that a diameter of the bushing inside of the coil is greater than a diameter of the bushing inside of the second housing part.

4. A solenoid valve according to claim 3 , wherein the shoulder lies outside of the magnetic flux of the solenoid valve.

5. A solenoid valve, comprising:

a first and a second housing part,

the first housing part with a tool engagement portion for screwing of the second housing part into an inner thread of a receptacle,

the first and second housing parts being joined to each other immovably, and

the second housing part having a tensile strength that is greater than a tensile strength of the first housing part,

wherein the tool engagement portion lies in a magnetic flux, a wall thickness of the first housing part in a region of the tool engagement portion being greater than the wall thickness outside of the magnetic flux.

6. A solenoid valve according to claim 5 , wherein a plunger is provided for opening and closing the solenoid valve, said plunger being mounted in a linearly movable manner inside of a bushing, which bushing is constructed with a shoulder in such a way that a diameter of the bushing inside of a coil is greater than a diameter of the bushing inside of the second housing part.

7. A solenoid valve according to claim 6 , wherein the shoulder lies outside of the magnetic flux of the solenoid valve.

8. A solenoid valve, comprising:

a first and a second housing part,

the first housing part with a tool engagement portion for screwing of the second housing part into an inner thread of a receptacle,

the first and second housing parts being joined to each other immovably, and

the second housing part having a tensile strength that is greater than a tensile strength of the first housing part,

wherein a plunger is provided for opening and closing the solenoid valve, said plunger being mounted in a linearly movable manner inside of a bushing, which bushing is constructed with a shoulder in such a way that a diameter of the bushing inside of a coil is greater than a diameter of the bushing inside of the second housing part.

9. A solenoid valve according to claim 8 , wherein the shoulder lies outside of the magnetic flux of the solenoid valve.

10. A solenoid valve according to claim 8 , wherein the tool engagement portion lies in a magnetic flux, a wall thickness of the first housing part in a region of the tool engagement portion being greater than the wall thickness outside of the magnetic flux.
