Abstract: A solenoid valve has a valve plunger which is guided in a passage bore of a valve housing. The valve plunger with its valve closing element is held in a basic position by a restoring spring. The basic position opens up a valve passage in a valve seat. The valve plunger is arranged between an inlet and an outlet channel in the valve housing. A magnet armature provides actuation of the valve plunger. An inlet chamber is connected to the inlet channel between the passage bore and the valve seat. The valve plunger protrudes into the inlet chamber by way of a step section. As a result of being hydraulically impinged on by the pressure medium of the inlet channel an axial force is generated on the valve plunger that acts oppositely to the closing direction of the valve plunger.

Abstract: A valve arrangement is inserted between a master brake cylinder and a reservoir in a housing of an electrohydraulic motor vehicle brake system which can be activated both by a vehicle driver and independently of the vehicle driver. The valve arrangement can be acted on by a volume flow which can be conveyed by a linear actuator in the direction of a pedal travel simulator, the working chamber of the pedal travel simulator being connected to the master brake cylinder, wherein, for the purpose of simplified construction and actuation, the valve arrangement has a hydraulically actuable non-return valve and a fixed orifice arranged parallel to the non-return valve. The non-return valve is arranged together with the fixed orifice in a valve carrier which is fastened to a closure plug which closes the housing of the motor vehicle brake system.
