ABSTRACT:
A pressure control valve for incompressible media, particularly for automatic motor vehicle transmissions, which is constructed as solenoid valve and in which the medium is conducted through a valve gap formed by a valve seat and a valve closure member; the valve closure member is acted upon by a force dependent on the control magnitude, especially on the magnitude of the torque; a predetermined force, produced by a force storage device, such as a spring, acts in the de-energized condition on the valve closure member connected with the armature of the magnet whereby the force is adapted to be varied by energization of the coil in dependence on the control magnitude; the iron casing surrounding the energizing coil terminates in two cylindrical pole shoes disposed concentric to one another and enclosing a ring-shaped magnet gap, whereby the armature carried by the armature support is attracted between the pole shoes with a more or less strong force depending on the coil energization; the armature support is thereby made of a material whose coefficient of thermal expansion coincides at least approximately with that of the material of the housing accommodating the winding and its iron casing while the armature, preferably subdivided into ring segments, is secured on the armature support.
