A magnetic valve for liquid and gaseous media having a flatbody slide valve which can slide with the aid of electromagnetic force between two planar-parallel slide surfaces. The slide surfaces include control openings. The slide valve comprises a core polarized by at least one stationary permanent magnet with at least one opening in the core being perpendicular to the planar-parallel slide surfaces. A pressure chamber is formed in the core with ends at both sides of the chamber. A cover surface borders an end wall of the chamber. At least two pair of corresponding control openings are inversely disposed. A connection bore having an opening at either end is in fluid communication with the pressure chamber. The edges of the bore openings serve to form control edges for the at least two pairs of control openings.

Magnetic valve for liquid and gaseous media

A solenoid-operated pressure-fluid valve for reversible control of both supply and exhaust functions of a double-acting fluid-pressure device. A valve body has an inlet port communicating with an inlet chamber and an exhaust-outlet port communicating with an outlet chamber. The valve body has first and second control-port connections for connection to the respective control ports of the double-acting device, and each of these connections communicates with a valve seat in each of the chambers. A rocker arm is pivoted between the two chambers and carries two valve members in each of the two chambers. In one solenoid-actuated position of the rocker arm, valve-member action in the inlet chamber establishes inlet-chamber communication exclusively with one control-port connection while the valve-member action in the outlet chamber establishes outlet-chamber communication exclusively with the other control-port connection; in the other solenoid-actuated position, valve-member action in the respective chambers is such as to reverse the exclusivity of chamber communication with the respective control-port connections.

Rocker lever solenoid valve

A solenoid valve for liquid and gaseous media whose valve closure piece or pieces (24) can be actuated by an armature (20') which is movable relative to the valve seat or seats (18, 19) is disclosed. The armature lies in the magnetic field of at least one electromagnet (4, 5) and of at least one permanent magnet (10) arranged outside the field of the electromagnet. The valve is closed via the armature (20') and has operating air gaps which change in opposite directions upon a movement of the armature. The electromagnet is provided with a core (4) whose ends form three magnet poles (10, 11, 12). The armature (20') which contains the permanent magnet (21) has two pole pieces (20') which extend between the three magnet poles (10, 11, 12) of the electromagnet to form four operating air gaps, the pole pieces being combined with the permanent magnet and connected with them to form as assembly.
