Patent ID: 6846050

Claim:
A hydraulic unit for an anti-lock vehicle brake system ( 1 ) having a housing block ( 24 ), comprising a first row of valve receiving chambers ( 25 , 26 , 27 , 28 ) for receiving inlet valves ( 10 , 11 , 12 , 13 ), and a second row of valve receiving chambers ( 29 , 30 , 31 , 32 ) for receiving outlet valves ( 14 , 15 , 18 , 19 ); a pump receiving chamber ( 68 ), whose longitudinal axis ( 70 ) extends at least approximately perpendicular to longitudinal axes ( 33 , 34 ) of the valve receiving chambers ( 25 - 32 ) and between the longitudinal axes ( 33 ) of the valve receiving chambers ( 25 , 26 , 27 , 28 ) of the first row and the longitudinal axes ( 34 ) of the valve receiving chambers ( 29 , 30 , 31 , 32 ) of the second row; low-pressure reservoir receiving chambers ( 36 , 37 ), which are disposed on a side, remote from the pump receiving chamber ( 68 ), of the valve receiving chambers ( 29 , 30 , 31 , 32 ) of the second row, and whose longitudinal axes ( 65 ) extend at least approximately perpendicular to the longitudinal axes ( 33 , 34 ) of the valve receiving chambers ( 25 - 32 ) and to the longitudinal axis ( 70 ) of the pump receiving chamber ( 68 ); and a separate, direct connection ( 60 , 61 , 62 , 63 ) between each valve receiving chamber ( 29 , 30 , 31 , 32 ) of an outlet valve ( 14 , 15 , 18 , 19 ) and an associated low-pressure reservoir receiving chamber ( 36 , 37 ).
