ABSTRACT:
An electromagnetic reciprocating motor or pump for use for providing mechanical force for actuation of other fluids or components, and includes a cylinder provided with closures at each end, at least a pair of electromagnets operatively associated with the cylinder, and surrounding the same, a magnetically responsive piston provided within the cylinder and capable of longitudinal shifting reciprocally within the cylinder upon the sequential energization of the electromagnets, and either a mechanical actuator or electronic triggering components cooperating with electrical circuitry and connecting with the electromagnets which upon energization charging the electromagnets in timed sequence for inducing their reciprocal shifting of the piston within the cylinder means. Electrical circuitry includes a power supply, a sequencing circuitry, coil driver circuitry, all of which upon their cooperative functioning provide for a regulating the rate, timing, and quantity of charge delivered to each of the particular electromagnets during operation of the reciprocating device.
