A solenoid valve for controlling a fluid has a first housing part () and an axial guide () facing inwards for an armature () that can be displaced in the axial guide () under the effect of a solenoid () that at least partially surrounds the exterior of the first housing part (). A return spring () and a closing element () impact a valve closing element (). A second housing part () is arranged coaxially to the first housing part (). The first housing part () has a reduced wall portion () that faces inwards towards the armature () and the second housing part () and that effects a magnetic separation of the two housing parts () to at least some extent.

Solenoid valve

A proportional power control valve includes a solenoid controlling a main piston. The main piston is in fluid communication, through a feed opening, with the valve intake, and cooperates with a servo-control piston to block the valve intake from the valve outlet. The servo-control piston is part of a cylindrical armature controllable by an electromagnet of the solenoid, and can be moved counter to the bias of a locking spring. The locking spring is guided in a receiving chamber in the cylindrical armature. Since the receiving chamber of the cylindrical armature is in continuous fluid communication with the valve intake through a connection formed in the armature by an attenuation opening, the resulting proportional power control valve allows the continuous adjustment of the volume flow of a pressure medium or pressurized fluid dependent upon the level of electric control current supplied to the electromagnet.
