Abstract
A magnet valve for anti-lock vehicle brake systems, having a valve inlet for a connection of a pressure source, and a valve outlet for connection of a pressure receiver. A valve member that controls the connection between the valve inlet and outlet. An electromagnet, which is triggerable by a minimum and maximum exciter current for actuating the valve member counter to a force of a restoring spring. A throttle, which is operative between the valve inlet and outlet for delaying a pressure rise at the valve outlet. The throttle is disposed for selective switching in the valve member, and the valve member is embodied such that by triggering of the electromagnet with the minimum exciter current (I.sub.1), the throttle between the valve inlet and the valve outlet is switched on, and upon triggering of the electromagnet by the maximum exciter current (I.sub.2) and in the absence of electromagnet triggering, the valve inlet and outlet are each disconnected from one another or made to communicate with one another, respectively.
