Abstract
An electromagnetically actuated valve has a sleeve which receives magnetically operative elements, such as an armature and a magnet core. The sleeve is provided with a radially outward-oriented, encompassing widened portion in the form of a flange having flat wall portions which extend transversely to the longitudinal axis of the valve and rest on one another essentially without an interstice between them. The flange is braced on a shoulder of a valve block bore and is hydraulically tightly gripped by material positively displaced from the bore circumference. The flange is the sole securing means for the fluid-carrying part of the valve, which part comprises the sleeve, armature and magnet core.
Claims3
An electromagnetically actuated valve (1), in particular for slip-controlled hydraulic brake systems of motor vehicles, comprising a sleeve (8) containing magnetically operative elements including an armature (9) and a magnet core (15), said sleeve having a radially outward-oriented encompassing widened flange (20) for securing the fluid-carrying part (2) of the valve (1) in a bore (4) of a valve block (5), said radially extending flange (20) being braced on a shoulder (23) of the bore (4) and being hydraulically tightly gripped by material positively displaced from the bore circumference,
- said flange (20) being formed by a widened portion of the sleeve (8) having flat wall portions (21, 22), extending transversely to the longitudinal axis of the valve, and which rest on one another essentially without an interstice between them.
