Abstract (en)
[origin: EP1420148A2] Liquid module (14) comprises an inlet (19) connected to an outlet (20) via a liquid channel (21), and a valve arranged in the liquid channel. The valve is a pressure-regulating valve (22) connected via an ON/OFF channel and a pressure-regulating channel (33) to the liquid channel. The pressure-regulating valve completely closes the liquid channel in a first position, and partly opens the liquid channel in a second position. In this second position the pressure-regulating valve can be adjusted into all intermediate positions. An Independent claim is also included for the production of constant liquid pressures in the above liquid module. Preferred Features: The pressure-regulating valve has a piston region (28) connected to the ON/OFF channel.
