Abstract

A non-linear, electromagnetic, vibration compression mechanism comprising a non-linear electromagnetic vibration device and a piston-cylinder, plunger-cylinder, or membrance type pump. A reciprocating compression section of the device may be axially arranged at a front or rear portion of the electromagnetic vibration device to form a coaxial compression device. Compression elements may also be installed on the lateral right and left sides or top and bottom of the electromagnetic vibrator to act non-coaxially but in parallel with the vibrator. The electromagnetic vibrator may drive one compression cylinder or several cylinders simultaneously. The reciprocating fluid compression device of the instant invention may be used to compress gas as well as liquid.
