Abstract
PURPOSE: To control relatively the magnetic attraction produced in each coil and give a piston automatic oscillation by connecting a condenser with each of two electromagnetic coils and making up a pair of series resonance circuits.
CONSTITUTION: A piston 3 makes reciprocation in response to change of the magnetic attraction produced by exciting coils 2a, 2b wound on electromagnetic cores 1a, 1b. A series resonance circuit is made up by connecting condensers 6a, 6b respectively in series with the coils 2a, 2b and the circuit is connected in parallel with an AC power source 5. The inductances of the coils 2a, 2b change in response to the elearance lengths Ga, Gb between the centers of coils 2a, 2b and piston 3. If the capacities of each condenser 6a, 6b are established so that resonance state may be produced when the piston lies at the most distant place from the center of either of the coils or shows the greatest clearance length, the average of the effective values and the magnetic attraction forces of ia, ib running through the coils in parallel to the travel of the piston changes by specific characteristics.
