Abstract
A solenoid valve having a first seat valve for performing a closing function and a second seat valve, connected in parallel thereto, for a pressure-limiting function. A pressure medium spilled by the second seat valve flows off through a flow-off bore acting as a throttle. Pressure surges are thus largely avoided in the part of the brake system located on the flow-off side. The solenoid valve can be used in controlled-slip hydraulic brake system of motor vehicles.
