Abstract
A metering device for a heating appliance has a pump arrangement for the delivery of liquid that is supplied via an inlet region to an outlet region and a valve arrangement by which the pump arrangement is connected with the inlet region to receive liquid or with the outlet device to deliver liquid. The valve arrangement has a valve member that is brought into a first actuating position in which the valve member permits a liquid flow from the inlet region to the pump arrangement and prevents a liquid delivery from the pump arrangement to the outlet region. In a second actuating position the valve member prevents a liquid supply from the inlet region to the pump arrangement and permits a liquid delivery from the pump arrangement to the outlet region.
