FIELD: excitation of elastic vibrations or initiation of air-operated wave transducers. SUBSTANCE: the device has a body, working chamber in it, control actuator made, for example, as an electromagnet coupled to a control valve, built-up movable seat of this valve. In addition the gate uses a service chamber, even one duct communicating it with the upper part of the working chamber, complete or partial hermetic overlap on the outer surface of the built-up movable seat. EFFECT: reduced consumption of power for opening the pneumatic gate, reduced overall dimensions of the device. 3 cl, 1 dwg
