Patent ID: 6869152

Claim:
In a hydraulic unit ( 11 ) for an electronically controllable brake system of a vehicle with a housing block ( 10 ), comprising at least one mounting face ( 12 , 14 ) for an electronic control unit, installation chambers ( 20 ) for hydraulic connections for supplying the hydraulic unit ( 11 ) with pressure fluid, installation chambers ( 26 , 24 , 18 i-k , 18 a , 18 b ) for pump elements ( 50 ) and damping devices ( 22 ), disposed downstream of the pump elements ( 50 ) for damping pressure pulsations, and for electrically triggerable pressure buildup values and pressure reduction valves for modulating the brake pressure at least one wheel brake cylinder communicating with the hydraulic unit ( 11 ), the improvement wherein the installation chambers ( 18 i , 18 k ) of the damping devices ( 22 ) and the installation chambers ( 18 a-h ) of the valves extend to the common mounting face ( 12 ) of the housing block ( 10 ) on which the electronic control unit can be mounted; and wherein the damping devices ( 22 ) protrude past this mounting face ( 12 ), further comprising an inlet ( 30 ) and an outlet ( 32 ) of the damping device ( 22 ) discharging into the installation chamber ( 24 ) for one of said pump elements ( 50 ); and wherein the one pump element ( 50 ), in the region between the inlet ( 30 ) and the outlet ( 32 ) of the damping device ( 22 ), forms a sealing point ( 59 ) together with the wall of the installation chamber ( 24 ) of the one pump element ( 50 ).
