Abstract: A solenoid valve for controlling a fluid has a first housing part (2) and an axial guide (3) facing inwards for an armature (4) that can be displaced in the axial guide (3) under the effect of a solenoid (5) that at least partially surrounds the exterior of the first housing part (2). A return spring (6) and a closing element (27) impact a valve closing element (7). A second housing part (9) is arranged coaxially to the first housing part (2). The first housing part (2) has a reduced wall portion (17) that faces inwards towards the armature (4) and the second housing part (9) and that effects a magnetic separation of the two housing parts (2, 9) to at least some extent.

Abstract: 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.
