<p>The device disclosed comprises a stack of superimposed reaction plates (14) which can be moved selectively and incrementally relative to one another and are provided with incrementally spaced passages (16), each passage forming a reaction chamber (18). Each plate (14) can be selectively moved relative to the rest of the stack by means of a plate adjusting device (56). A pressure element (100) of a clamping device is arranged between a pressure position with sealing intermediate clamping of the plates and a released position permitting free relative movement of the plates. A force-transmitting device in the form of a double-armed lever (80) couples the plate adjusting device with the pressure element (100) so that when the plate adjusting device moves beyond one of the two outer plate adjustment positions into an end position, the pressure element is moved into the pressure position.</p> |
