Abstract:
A method for opening a single plate valve (16, 60), separating a flow channel (8, 62) from a working chamber (10, 64) or connecting the flow channel (8, 62) with the working chamber (10, 64), wherein the valve in an open position projects into the working chamber (10, 64), said method comprising the steps of:directly withdrawing energy from a flow flowing out of the working chamber (10, 64) into a flow channel (8, 62) as soon as said plate valve begins to open, said flow resulting from excess pressure within the working chamber (10, 64), wherein said plate valve effectively opens a passage between the working chamber (10, 64) and the flow channel (8, 62) remains completely open;using the withdrawn energy for supporting further opening movement of the valve (16, 60).
