Abstract
A solenoid valve () is described comprising a first port (), a second port (), a valve element () and a valve seat () arranged between said first port () and said second port (), a coil () and a yoke arrangement (-), said coil () being magnetically linked to said yoke arrangement (-), said yoke arrangement (-) having a movable armature (). In such a solenoid valve the generation of noise should be kept low. To this end said valve element () is driven by a pressure difference between a first pressure on a first side () of said valve element () and a second pressure on a second side () of said valve element (), at least one of said first pressure and said second pressure being controlled by means of said armature (), wherein said armature () comprises a first front face () at a first end and a second front face () at a second end opposite said first end, said first front face () and said second front face () being connected by a first flow path (), said first flow path having first throttling means for keeping low a flow of a fluid flowing through said first flow path ().
