Abstract

A housing of a multiway valve contains several inlets and outlets and a chamber containing several valve seats, each of which is allocated to one of the outlets. A closing device can be displaced between the valve seats. A cylinder contains a cylinder chamber having a fluid. A heating device is provided for heating the fluid and a plunger is provided that can be displaced in the cylinder by the pressure of the fluid. By its displacement, the plunger is able to dislodge the closing device from one of the valve seats.
