Abstract
A solenoid distribution valve has a housing, a valve chamber integrated in the housing and a first valve seat bore for connection to a first line, a second valve seat bore as a connection to a second line and a clear opening to a third line, an electromagnet, and a valve lifter that can be moved by the electromagnet. A valve lifter within the valve chamber includes a first sealing surface facing the first valve seat bore and a second sealing surface facing the second valve seat bore that are optionally closable. The valve lifter extends out of the valve chamber through the second valve seat bore to the electromagnet. When the second valve seat bore is closed, the valve lifter is drawn, via a differential pressure ratio, by the pressure in the second line, into the second valve seat bore.
