PCT No. PCT/DE94/01098 Sec. 371 Date Jun. 12, 1996 Sec. 102(e) Date Jun. 12, 1996 PCT Filed Sep. 21, 1994 PCT Pub. No. WO95/08462 PCT Pub. Date Mar. 30, 1995The object is to reduce the weight of the hydraulic unit. The hydraulic unit (12) has a metal valve block (11) with at least one stepped receiving bore (15) for the hydraulic portion of an electromagnetically actuated valve (10). The hydraulic portion (13) is provided with a securing flange (30), which is inserted into a step (46) of the receiving bore (15) and is positionally secured by a caulking (48) formed from the metal of the valve block (11). A valve dome (16) protruding beyond the boundary plane (17) of the valve block (11) carries the electric portion (14) of the valve (10). The savings in weight is attained by using light metal, such as an aluminum alloy or the like, for the valve block (11). The hydraulic unit is intended for traction-controlled brake systems of motor vehicles.
