Patent ID: 8500215

Claim:
A hydraulic unit for slip-controlled braking systems comprising: a parallelepipedic receiving body which receives at right angles to an upper face currentlessly open and currentlessly closed valves in a plurality of valve receiving bores of a first and second valve row; accumulator receiving bores arranged at a distance from and at right angles to the first and second valve rows; a plurality of pumping device receiving bores which are bundled in groups associated with a plurality of hydraulic circuits, the pumping device receiving bores being arranged parallel to the upper face at a distance from one another; a drive shaft with three separate eccentrics (X 1 ,X 2 ,X 3 ) positioned with respect to imaginary horizontal planes (E 1 , E 2 , E 3 ) for driving pumping devices; a plurality of pressure medium channels which connect the pumping device receiving bores to the valve receiving bores in order to establish a hydraulic connection between the pumping devices and wheel connections; and wherein the imaginary horizontal planes (E 1 , E 2 , E 3 ) that are each arranged parallel to the upper face and each receive two pumping device receiving bores arranged in a V-formation with an aperture angle (α) for pumping devices, wherein two pumping device receiving bores of a common hydraulic circuit are arranged perpendicularly to the upper face and congruently in respective planes one above the other in a vertical direction, and wherein one pumping device receiving bore of the same hydraulic circuit is offset by an acute angle (γ) with respect to the two other pumping device receiving bores.
