<p>A flow control valve has a supply line connection, and at least one discharge line connection, and is characterized by at least one fine-control valve whose flow rate is continuously or semicontinuously variable and at least one two-position valve having a minimum flow rate in one stable position and a maximum flow rate in another stable position. The inlet of the or each tow-position valve and the or each fine-control valve is in fluid communication with the supply line connection, and the outlet of the or each two-position valve and the or each fine-control valve is in fluid communication with the or each discharge line connection. In accordance with a further elaboration, the flow control valve may comprise a series of two-position valves, with the maximum flow rate of the successive two-position valves in the series doubling in each case, and the minimum flow rate of each two-position valve being zero.</p> |
