FIELD: machine building. ^ SUBSTANCE: magnetic device of valve control is installed on fixed core of valve and includes permanent magnet and non-magnetic body, carriage, axis, return spring, rotary drive actuated externally. Permanent magnet fixed on carriage and arranged in a certain manner towards stop of fixed valve core so that magnetic field magnetises stop to the maximum, moves along trajectory with efficient change of magnetic field effect at stop, by change of permanent magnet flow direction without increase of friction forces in pair of fixed and movable cores sliding. ^ EFFECT: elimination of necessity to use power in valve control, increased reliability and safety in its operation. ^ 11 dwg |
