Abstract:
PCT No. PCT/DE94/01099 Sec. 371 Date Mar. 25, 1996 Sec. 102(e) Date Mar. 25, 1996 PCT Filed Sep. 21, 1994 PCT Pub. No. WO95/08463 PCT Pub. Date Mar. 30, 1995An electromagnetic valve having a magnet armature which can be moved longitudinally in a valve dome and the valve tappet of which carries a closing member of a first seat valve, which valve is open in the rest position. The first seat valve is situated in a valve chamber, from which first and second pressure-medium passages lead to first and second chambers arranged axially at both ends of the magnet armature. The connection between the first control chamber, which is remote from the closing member, and the second chamber, which is close to the closing member, is controlled by the magnet armature by a second seat valve, which is open in the rest position. When the second seat valve assumes its closed position, the pressure in the first control chamber, which is remote from the closing member, brings about a displacement of the magnet armature counter to the force of a return spring, resulting in a reduction in the cross section of flow of the first seat valve. The aim is to achieve automatic setting-which is effective following a closed position of the valve-of a reduced section of flow. The valve can be used in slip-controlled hydraulic brake systems of motor vehicles.
