Abstract
A reciprocating compressor capable of producing a steady-state, continuous, non-pulsing outflow at volumes less than 25 gallons per hour. The compressor utilizes at least two pistons driven in a near axial manner with any lateral forces imparted to the compressor subsequently removed. The compressor is useful in a vapor compression distillate system but could also be adapted to pump liquids. A rotating cam is provided which through cam followers drives the pistons such that the compression stroke of one compensates for the vibrational force introduced into the apparatus by another piston caused by change in that piston's direction.
