<p>@ The invention relates to a valve arrangement (10) for supply steam and cooling water under pressure alternately to a compression moulding tool, via respective inlet valves (26,28). Upstream of the inlet valve (28) cooling water taken from the cooling-water circuit is passed to piston arrangements (36,38), which act upon the inlet valves (26,28), and is used both as a working medium for the piston arrangements and as a cooling agent therefor.</p> |
