PCT No. PCT/DE93/00886 Sec. 371 Date Jun. 15, 1994 Sec. 102(e) Date Jun. 15, 1994 PCT Filed Sep. 18, 1993 PCT Pub. No. WO94/08831 PCT Pub. Date Apr. 28, 1994.A solenoid valve with pressure limitation for motor vehicle brake systems with slip control. The solenoid valve has a seat valve with the valve seat, valve element and restoring spring, which holds the seat valve in an open position. The valve element is fastened on a valve tappet, which is axially displaceable in a valve housing and is transferred into a seat-valve-closed position by an electromagnet when the electromagnet is supplied with current. In the valve-closed position, there acts a pressure-limiting spring, which fixes the valve-opening pressure of the seat valve. To achieve a structurally simple valve design with the advantage of simple and accurate setting and adjustment and also of simplified forward assembly of the solenoid valve, the valve tappet is subdivided into first and second tappet elements which are coaxial to each other and relatively displaceable, of which the first tappet element bears the valve element and the second tappet element can be driven by the electromagnet. The pressure-limiting spring is supported between the first and second tappet elements.
