Abstract:
1. A solenoid valve, for slip-controlled motor vehicle braking systems, comprising: a first and a second valve closing body arranged in a valve housing, which valve closing bodies, disposed coaxially in the valve housing, are able to open or close a first and a second valve orifice in a stroke-dependent manner; a magnet armature which forms with the first valve closing body an assembly which can be manipulated independently and which can be placed on the second valve closing body under the effect of a return spring, the second valve closing body is accommodated in an axially movable manner within a guide sleeve fixed in the valve housing; a magnet core in the valve housing against which an end of the return spring oriented away from the assembly bears; a pressure medium inlet which opens into the valve housing and a pressure medium outlet, the first valve closing body being able to open or close the first valve orifice located in the second valve closing body as a function of the electromagnetic excitation of a valve coil, the clear cross section of the first valve orifice is smaller than that of the second valve orifice in the second valve closing body which is openable under the influence of a spring; and a substantially pot-shaped coupling element which is mounted on a magnet armature extension and in which the first valve closing body is received movably relative to the magnet armature, wherein the coupling element contacts zonally an inner wall of the guide sleeve.
