ABSTRACT:
A valve for simultaneous control of two fluid flows has two control elements linearly movable along parallel axes. The control elements pivotally engage opposite ends of a lever, and the lever is itself pivotally mounted on a part which is linearly movable to lift the control elements. The pivotal interconnection between the lever and the linearly-movable part can be locked by application of an electric control current. Locking can be effected by means of an electro-magnet or by interposing between the lever and the part a liquid whose viscosity is increased by the control current.
