Abstract

PURPOSE: To increase the power and efficiency of the pump by causing a magnetic field generated in an electromagnetic coil to effectively act upon a permanent magnet of a piston to increase the reciprocating and sliding force of the piston.
CONSTITUTION: When an AC current is flowed to electromagnetic coils 16 and 17, a magnetic field is generated in the magnetic coils 16 and 17. A magnetic field induction plate 23, iron cores 14 and 15, a suction side mouth piece 20 and an outlet side mouth piece 21, a cylinder 8, a piston 11 and a frame 24 are constructed by a magnetic material, and effectively pass a magnetic flux. The piston 11 is attracted and repulsed depending upon the polarities of the permanent magnets 9 and 10, and performs a reciprocating and sliding operation within the cylinder 8. By this operation, a fluid or a gas 25 is sucked up from the side of a suction side mouth piece 20 by the operations of check valves 13 and 22, and the fluid or the gas 25 is exhausted through the exhaustion side mouth piece 21.
