Abstract
Very rigorous demands to use less energy stimulate the development of more economic and non-polluting pneumatic valves. A lot of this demands is not possible to realize with the use of classical electromechanical transducers for the valve control and with the use of classical materials for the valve parts. The aim of this research project is to analize the possibilities of use of piezoactuators for the pilot operation of the pneumatic valves. Electrical control of piezoactuators (valves) will be realized directly with computer and PC-Bus. According to this, the use of the electrical energy will be reduced (from 3 to 6 W normally) to 10 to 20 mW. As control elements in pilot valves, the multilayer bending piezoactutors with charging voltage up to 60 V will be used. At the designing and construction of the valves, alternative materials (plastic materials, ceramics) will be used. This will make possible to use non-oiled air. The use of alternative materials and actuators will also make possible to build miniaturized and cheapper pneumatic valves.
