The valve element (62) of one valve arrangement has a guide section (60) at least partly housed in a guide opening (58) formed in the valve element (72) of the other valve arrangement. The peripheral surface of the guide section and/or the guide opening has at least one recess reducing the contact surface between the guide section and the guide opening.
