A valve means which comprises a control chamber in a valve housing and into which several fluid duct open. In the control chamber there is at least one pivoting control rocker member serving for the control of at least one of the fluid duct openings and able to be moved between two terminal positions, one pivotal position of such control rocker member being influenced by an electrically activated flexible element. The flexible element may act within the control chamber on an actuating part of the control rocker member. The latter is biased by spring means into a first terminal position, the flexible element engaging the actuating portion of the control rocker member in the electrically non-excited state mechanically free of stress and without any spring bias.
