Electrohydraulic pressure control device for automotive brake systems

[0033] Figure 1 shows a combined ABS / ESP control. The controller 1 , the valve group 2 and the motor unit 23 represent a compact structural unit as installed in a motor vehicle for the control operation of the brakes generally. To this end, the valve block 2 is connected to a hydraulic line (not shown). The electronic control unit 7 on the printed circuit board 6 can engage the wire harness through the engaging plug 9 . Protrusions 21 on the cover push the printed circuit board 6 in the direction of the valve block 2 opposite the electrical contacts of the valve coil 4 .

[0034] The shape of the one-piece controller housing corresponds substantially to that of a thin-walled metal housing that is open at the bottom. Accordingly, the controller housing is composed of a housing volume area 3 and a housing cover area 5 .

[0035] The motor unit 23 is electrically connected through an insulated plastic adapter (motor plug) 38 with metal contained therein, which leads to the pum...
