<p>The machine has valve arrangement (4) with an electric controllable volume flow switching valve (3) arranged with two passage positions in a supply line (1). The valve passes water into the both passage positions, such that lesser water is passed into one of the position than in another passage position. The switching valve comprises two channels, which are connected parallel to each other. A flow resistor i.e. volume flow regulator (18), is arranged in one of the channels, and another channel is locked with a shut-off valve (20). A safety valve (2) is arranged in the switching valve.</p> |
