  • Electromagnetic reciprocating pump and motor means
    Patent number: 4692673
    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.
    Type: Grant
    Filed: July 29, 1985
    Date of Patent: September 8, 1987
    Assignee: Sanford D. DeLong
