Abstract
A solenoid valve has a housing, which has a fluid inlet and a fluid outlet, and an electromagnetic drive, which comprises a solenoid with a fixed core and a movable armature, wherein the armature interacts with a valve seat. A pressure compensation chamber which is bordered by a membrane is formed in the armature, wherein the pressure compensation chamber is in fluid connection in terms of flow with the fluid inlet by means of a pressure compensation channel.

A solenoid valve with a housing, which has a fluid inlet and a fluid outlet, and an electromagnetic drive, which comprises a solenoid with a fixed core and a movable armature, wherein the armature interacts with a valve seat and wherein a pressure compensation chamber, which is bordered by a membrane, is formed in the armature, wherein the pressure compensation chamber is in fluid connection in terms of flow with the fluid inlet by means of a pressure compensation channel wherein a fixed support component with a bearing surface is provided, against which a supporting surface of the membrane rests on a side facing the core and the supporting surface is provided in the center of the membrane.
A solenoid valve with a housing, which has a fluid inlet and a fluid outlet, and an electromagnetic drive, which comprises a solenoid with a fixed core and a movable armature, wherein the armature interacts with a valve seat and wherein a pressure compensation chamber, which is bordered by a membrane, is formed in the armature, wherein the pressure compensation chamber is in fluid connection in terms of flow with the fluid inlet by means of a pressure compensation channel wherein a fixed support component with a bearing surface is provided, against which a supporting surface of the membrane rests on a side facing the core wherein the membrane has an annular protrusion pointing towards the core, which surrounds the supporting surface.
A solenoid valve with a housing, which has a fluid inlet and a fluid outlet, and an electromagnetic drive, which comprises a solenoid with a fixed core and a movable armature, wherein the armature interacts with a valve seat and wherein a pressure compensation chamber, which is bordered by a membrane, is formed in the armature, wherein the pressure compensation chamber is in fluid connection in terms of flow with the fluid inlet by means of a pressure compensation channel, wherein the armature has an upper part close to the core and a lower part remote from the core, wherein a circumferential edge of the membrane is clamped between the upper part and the lower part.
