<p>The multi-port valve has two valve seats (24,25) each provided on a corresponding movable valve seat component (26,27) spring-loaded in the direction of the valve's electrically activated flexural actuator (12) and in the center position of the actuator by occupying a closed position lie simultaneously on the actuator so that the port mouths (22,23) are closed. With deflection of the actuator in one direction or the other it displaces the corresponding valve seat component while maintaining its closed position against spring force, and is simultaneously lifted from the other seat, opening the port mouth.</p> |
