1. An electromagnetic reciprocating means for use for providing mechanical force for actuation of other means comprising a cylinder means, electromagnetic reciprocating means comprising a motor means, a closure means provided at each end of the said cylinder means, at least a pair of electromagnets operatively associated with said cylinder means, a magnetically responsive piston provided within said cylinder means and capable of longitudinally shifting reciprocally within said cylinder means upon the sequential energization of said electromagnets, an electrical circuitry means connecting with said electromagnets and upon energization charging said electromagnets in progressively timed sequence for inducing the reciprocal shifting of said piston within said cylinder means, said motor means comprising a linear reciprocating motor means, a drive shaft connecting with said piston, there being an aperture provided through a closure means at least at one end of said cylinder means, said drive shaft extending through the closure means aperture and furnishing linear moving force upon the reciprocating movement of said motor means piston, a seal formed between the reciprocating moving drive shaft and the closure means aperture, a spacer means provided between each of the adjacent electromagnets and the closure means, each electromagnet and the said spacer means provided substantially surrounding the internally arranged cylinder means, fastener means tightly securing the closure means, internally arranged cylinder means, spacer means, and electromagnets together, said reciprocating means as secured together being hermetically sealed, and seal provided between the internally arranged cylinder and the closure means to prevent leakage at their areas of contact.
