ABSTRACT:
A compact hydraulic unit for slip-controlled brake systems with several hydraulically, mechanically and/or electrically operable functional elements (e.g. accumulator, valve elements, pressure generating and driving elements) arranged in an accommodating member, with several pressure fluid channels connecting the functional elements. The pressure fluid channels create a hydraulically operable connection between at least one pressure fluid supply means and one pressure fluid consumer. A control device can be connected with the valve and the driving elements by means of electrical conductors. The valve elements are arranged in several valve accommodating bores of the valve accommodating member in a first and a second row. Pressure fluid bores are provided between the two diametrically extending valve rows which connect the valve elements and location bores containing the pressure generating element and the driving element. Outside the two valve rows, there are further location bores in the valve accommodating member in which pressure accumulator pistons are positioned.
