Abstract:
1. A hydraulic unit for regulating the brake pressure in a vehicle brake system, comprising: a housing block; valve receptacles defined by the housing block for receiving electronically triggerable solenoid valves; pump receptacles defined by the housing block, the pump receptacle being oriented transversely with respect to the valve receptacles; pump elements disposed in the pump receptacles and configured to be actuated by a drive; hydraulic connections defined by the housing block, the hydraulic connections including a first master cylinder connection for connecting the housing block to a master cylinder and at least one wheel brake connection for connecting the housing block to at least one wheel brake; pressure fluid connections for carrying brake fluid in the housing block, which put the valve receptacles, the pump receptacles, and the hydraulic connections in hydraulic communication with one another; a first solenoid valve (reversing valve) disposed in a first valve receptacle, the first valve receptacle being fluidly connected to the first master cylinder connection, the first solenoid valve being configured to block a flow of brake fluid from the at least one wheel brake connection to the first master cylinder connection; a second solenoid valve (high-pressure on-off valve) disposed in a second valve receptacle, the second valve receptacle being fluidly connected to a first pump receptacle, the second solenoid valve being configured to control a flow of brake fluid into an intake side of the pump element in the first pump receptacle; and a bore defined in the housing block that fluidly connects the first valve receptacle to the second valve receptacle, wherein the valve receptacles include a row of inlet valve receptacles and a row of outlet valve receptacles, wherein the row of inlet valve receptacles and the first valve receptacle are positioned between the pump receptacles and the top side portion of the housing block, and wherein the row of outlet valve receptacles and the second valve receptacle are positioned between the pump receptacles and the bottom side portion of the housing block.
