Abstract:
An electromagnetic valve arrangement, for a pressure medium of a vehicle braking system, comprisingan electromagnet arrangement (12, 15) which is coupled witha valve closing means (18, 22) which can be brought into several positions (I., II., III., IV.);a housing (30) with a first, a second, a third, and a fourth connection (32, 34, 36, 38) of whichin a first position (I.)the first connection (32) and the second connection (34) are in flow connection with each other, andthe third connection (36) and the fourth connection (38) are blocked;in a second position (II.)the first connection (32), the second connection (34), the third connection (36), and the fourth connection (38) are blocked;in a third position (III.)the first connection (32) and the second connection (34) are blocked, andthe third connection (36) and the fourth connection (38) are connected with each other; andin a fourth position (IV.)the first connection (32) and the third connection (36) are connected with each other, andthe second connection (34) and the fourth connection (38) are blocked; characterised in that the valve closing means further comprises a first valve member (18) which is associated with a pressure reducer (52) which reduces the pressure prevailing in the pressure medium between at least two outlets (32,36).
