Abstract:
1. In a hydraulic assembly for slip-controlled brake systems of motor vehicles, having a valve block ( 8 ) with receiving bores ( 6 ), each for a hydraulic part ( 2 ) of electromagnetically actuated valves ( 1 ), each of which contains magnetically active elements, such as an armature ( 16 ) and a magnetic core ( 24 ) of a valve dome ( 10 ) that contains the hydraulic part ( 2 ), and a respective electric part ( 4 ), which is slid onto the valve dome ( 10 ) and has an electric coil ( 50 ) encompassing this valve dome ( 10 ), a coil housing ( 52 ), and a washer ( 54 ) that is contained at least indirectly in the coil housing ( 52 ), on the side oriented toward the hydraulic part ( 2 ) which closes a magnet circuit from the magnetic core ( 24 ) to the armature ( 16 ) via the coil housing ( 52 ), the improvement wherein the washers ( 54 ) of at least some of the valves ( 1 ) are interconnected to form a multi-washer component ( 60 ), the washers ( 54 ) being disposed next to one another, essentially in a plane, and connected to one another by means of bridge pieces ( 58 , 58 a , 58 b ), wherein in the assembled state, the bridge pieces ( 58 , 58 a , 58 b ) protrude through radial notches ( 72 ) provided in ends of the coil housings ( 52 ) in such a way that faces ( 68 ) of the washers ( 54 ) oriented toward the hydraulic part ( 2 ) of the valves ( 1 ) are flush with an end surface ( 70 ) of the associated coil housing ( 52 ).
