The invention proceeds from a hydraulic unit (10) for regulating the brake pressure in a vehicle brake system. Hydraulic units of said type are the core component of an anti-lock vehicle brake system, of a drive slip vehicle brake system or of a vehicle brake system which regulates driving stability. The invention proposes a particularly advantageous arrangement of the required recesses in a housing block (50') of a hydraulic unit. On account of said arrangement, the housing block (50') can be reduced in terms of its dimensions, and can be produced with a lower weight and more simply in terms of production. For this purpose, according to the invention, the second pressure medium connection from one of the ports (74,76) of the master brake cylinder (10) to the suction side of one of the pump elements extends through the valve receptacle (104,106) of the switching valve (USV; 40).
