Publication number: 20220373096Abstract: 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.
