Abstract
An electromagnetically actuatable double seat valve, has a housing having a housing opening and a throughgoing longitudinal opening, a valve body formed as a cylindrical hollow body slidingly guided in the housing opening, an electromagnet having an armature, a plunger fixedly connecting the armature of the electromagnet with the valve body so as to actuate the valve body and slidingly guided in the throughgoing longitudinal opening. The longitudinal opening has a part which faces away of the electromagnet and forming a consumer connection, a container connection and a pump connection. A pressure spring loads the valve body against the plunger so that a passage leads from the consumer connection to the container connection. The valve body has an end side facing away of the armature and provided with a radially outwardly extending collar. A plate closes the housing opening and supporting the pressure spring. A first flat seat is in the housing and a second opposite flat is on the plate. The collar has one side cooperating with the first flat seat formed in the housing and another side cooperating with the second flat seat formed on the plate.
