FIELD: mechanical engineering.
SUBSTANCE: valve actuating gear comprises a body with inlet, outlet and communication ports with an actuator, two shutting-off devices kinematically connected through a double-arm lever, two compression springs and a shutting-off device control gear. The control gear comprises two electromagnets with a permanent magnet. Windings of said electromagnets are electrically coupled in such a manner that feed voltage supply involves a sense of magnetic field of one of the electromagnets matching with that of its permanent magnet. For the other electromagnet, the senses are opposite. Each shutting-off device is rigidly connected with an anchor of the coupled electromagnet and connected with the double-arm lever by means of a pin joint. The shutting-off devices are counterbalanced with respect to an axis of rotation of said lever.
EFFECT: improved impact and vibration resistance and provided performance with maintained power consumption, reduced impact blow force.
